This video segment is from "Beyond Is Genesis History? Vol 2 : Life & Design," where we explore the fascinating fields of biology, genetics, and intelligent design. Check it out on our website: http://bit.ly/2QlPtQV.
Biologist Todd Wood introduces us to the concept of 'created kinds' and then talks about how that explains the origin of species we see in the world today.
Dr. Wood has a BS in Biology from Liberty University in Virginia (1994) and a PhD in Biochemistry from the University of Virginia (Charlottesville, 1999). Immediately following his PhD work at Virginia, Dr. Wood accepted a position as the Director of Bioinformatics at the Clemson University Genomics Institute (Clemson, South Carolina). After working for about two years at Clemson University, Dr. Wood accepted a faculty position at Bryan College (Dayton, Tennessee) in 2002. He is now president of the Core Academy of Science.

so todd what
got you interested in biology oh i've
always been
interested in biology i can't remember a
time when i wasn't i remember you know
three four years old going to the
brookfield zoo in chicago and
the detroit zoo and being pulled around
little red wagon you know
my parents and looking at all the
animals it was amazing and it's just an
amazing thing and i just sort of knew
there was always going to be these kinds
of creatures in my future somehow
todd when we walk around a zoo like this
i mean the first thing is just the
beauty of all of these creatures
but that beauty seems to be
found in that diversity there is just so
much
difference a beautiful difference in all
those creatures
and yet there's something similar about
them
as a biologist what do you see when you
see all of these creatures
yeah when i look at these lions
specifically i'm
seeing cats myself and you know all the
other
cats they have here at the zoo they all
have this
underlying catness to them
that's really apparent it's really
apparent when
they start playing right you're seeing
them lick themselves
and clean themselves or you see them
playing with some sort of ball or
something and they look
they're just like a cat they look like a
cat i mean this is like kittens play
around and they do that sort of thing
and so for those kinds of things the
scientists would put that into a family
called felidae
and i would understand the felids to be
representatives of a single created kind
so the continuity the similarity there
is so significant
that i'd say yeah these guys have all
descended from a single
pair of critters that was on the ark and
that eventually generated all the
different sorts of cats that we have
today
well todd how do we get all of that
diversity the other cats but
they look different yeah they definitely
look different
that's a good question where do we get
all this diversity so
for an evolutionist of course they would
argue that it's natural selection and
many years of mutations and changes
but for creationists i'm looking at this
thinking
these designs are already built into
whatever cat came off the ark
with noah and over time then those
characteristics have been expressed as
the cats have dispersed and spread out
over the world
just like we see in dogs oh kinds of
dogs how does that
dogs are a great analogy i mean in only
a few hundred years we've taken
essentially a wolf-like creature and
turned it into all these crazy breeds
the chihuahua and the saint bernard and
the german shepherd
and i think that's kind of what's going
on here with the cats there's
within that cat that came off the ark
those two cats that came off the ark
they had all the potential necessary to
generate the various
forms of cats that we have today it was
just a matter of breeding it out and
dispersing the
dispersing the cats around the world and
as they went then
then you have the lions and the tigers
showing up
later on so originally the the cat
and the original dog they there was a
lot of potential then within them but
genetic
potential huge genetic potential all
programmed inside of these critters
just waiting to come out so that over
time
in the in the breeding that we've done
with dogs we're basically just kind of
uh separating some of those genes out
yeah yeah so
so there's that all that potential
that's in the dog kind in the dog
genome whatever it is that gets
expressed as we
sort of tease out different parts of
various
genetic traits and combinations you get
dalmatians and whatever
that's the same sort of thing that's
happening here with the lions
so rather than just a a random accident
it appears as if all of these different
species are coming from a really
elaborate design oh absolutely and it's
not just a design like god you know
designed and created the lion it's god
created something that could make a lion
so it's more like you know a multi-tool
or a swiss army knife where you've got
all these pieces that you can just pop
out whenever you need them
but it's all just one thing that's
exactly what i think god created
cats to be like you have these traits
that can come out
when they're needed uh we can see some
of these variations come out
even today so you take a lion here you
cross it with a tiger you'll get a liger
but that thing will be much bigger than
either of its parents
so those are traits that come out and
the beautiful thing is even amidst all
this variety
and variation and generating diversity
you can still
end up with this cat right so you end up
with a liger that's a real cat it works
you know
it's not like these are broken things or
degenerated things
they're the real deal the amount of
design that we're talking about here is
just
way more than just god making one
critter fit for one place it's making a
critter that can make other critters
that are fit for
places that we've maybe maybe not even
encountered before
and it's just an amazing design it's so
much bigger than what we used to think
of as design
okay so we have cats and dogs as kinds
what are some other examples
oh there's lots there's the sea lions
that we looked at this morning
we've got grizzly and polar bear they're
members of the bear kind
duck swans and geese the members of the
duck kind
and now the dogs are really interesting
so in russia they did this experiment
where they tried to breed
foxes to be more tame right they ended
up with these
foxes that looked like little dogs the
ears started to droop
and they started to bark which is really
weird and so just by
breeding for a single trait you can end
up making all sorts of other weird
changes
in the the appearance of these dogs
which i think is another great example
of how
you know the traits that we think of as
defining a species or really
they're all embedded into different
members of a single created kind
so those foxes actually were still
carrying that
dog kind within them oh yeah that's
that's the amazing thing
how does this happen that's a good
question how does it happen we
we don't really know one of the things
that we can tell is when we're looking
at the various genomes of dogs
we see that their chromosomes are all
scrambled around and changed up
quite a bit it's really amazing and so
then you might think well maybe that has
something to do with how
they change and how they differentiate
but then
the camel and llama which are all
members of a camel kind
their genomes are almost exactly the
same so even when you think oh that must
be this the genomes get scrambled
nope there are other kinds which are
really different and they don't have
scrambled genomes at all so it's really
it's a baffling mystery how how these
various
traits end up coming out of an organism
it's
just really weird well todd that's kind
of fascinating now to think
about what god was doing when he was
bringing
two of every kind what do you think was
going on there oh yeah
he doesn't have to bring every little
variety
onto the ark so you've automatically got
room to spare
basically when you actually do the
calculations and okay so we don't know
exactly how many creative kinds there
were on the ark but maybe a couple
thousands
and they're small most animals are quite
small so you have
room to spare literally room to spare on
the ark
with for all the provisions and and noah
and his family
and all of that diversity that we have
today
is built into those two of every kind so
they get off the arc
they start spreading out encountering
new environments so you get
and the rabbit kind you know some
rabbits move up into the arctic and of
course
then you get your arctic hares with
their beautiful white fur
other rabbits are going out west uh in
the u.s where you have
grasslands in the plains and they're
getting really long legs so they can run
really fast because there's not a lot of
places to hide
they're also getting coloration that
matches their environment
it's an amazing amazing thing that's all
sort of built into that
whatever that rabbit was that got off
the yard so that also then uh
gives kind of a neat uh picture of when
god told the animals and human beings to
fill the earth it's
it's not just phil it's really it's
exploding isn't it you are
it's not just you know becoming more of
you you know go make more of what you
are
it's a matter of actually filling all
the little habitats and niches and
environments that we have on the planet
and it makes sense then when we go out
and scientists continue to be surprised
when we find
you know bacteria living you know miles
underground or you know we find
these weird environments where you'd
think hot springs
at yellowstone you'd think there's no
way any critter could live in there and
yet they do
so filling the earth yeah we filled the
earth
pretty effectively but we're talking
about
kinds uh that were on the ark yeah
people sometimes equate that with
species can you
help us get those species has a really
weird history and and trying to
understand exactly
where the species idea came from when
you look into the history of it you
realize it's really coming
out of people studying reproduction
people used to think that if you left a
piece of meat out to rot
it would turn into flies right and so
this guy named francesco reddy
he started doing experiments and
realized no no it's because flies lay
eggs on the meat
and then the baby flies come from the
same kind of fly that laid the eggs on
the meat
and so he called those things species
and that led to the idea well
you know if species always produce more
of the same species then
you go back far enough you come to
creation right it wasn't until later in
the 18th century that people began to
realize
it's not really clear what these species
are and it's pretty clear that sometimes
they can be really variable
and sometimes they can even change and
so people
began to think there must be another
category here that's not
the species that god was the original
creator of
because species can really change in
pretty dramatic ways
todd i think a lot of people think that
uh
the animals that came off the ark were
all the animals that we see
they came off the ark and then they just
they stayed that way but you're telling
us that's not the case oh yeah
the ark the ark pictures and the
cartoons with all the lions and the
tigers and the
and the and the zebras and the horses
that is really unrealistic really
unrealistic
plus noah looks like us i mean he's a
white guy that's very unrealistic too
uh yeah the the ark you might not have
even recognized it but the cool thing
about it is you would have recognized
things you would have said hey that
looks like a horse
hey that looks like a cat hey that looks
like a dog even though you might not
have
known exactly what kind of cat or dog or
horse it was but you could have at least
recognized yeah i know what that is i
can see
that that is a member of that creative
kind that's the amazing part
so if we have uh the horse kind
or the dog kind coming off the ark
how can we get so many so rapidly is
that possible
that's that's a good question and when
you look at the history of dog breeds
and you can see only in a few hundred
years
we can generate all this diversity i'm
not really that worried
about generating the diversity that we
see in created kinds i think it's
possible
it's just a matter of keep hammering
away at it and trying to understand
exactly what's going on there
because we're just at the beginning now
of understanding genomes i mean when i
was in
when i started grad school we kind of
had a
idea of how genomes and genes worked i
mean
basically the year after i started grad
school was the first
genome sequence published it was a
bacterium
so i was there as the genome revolution
was happening it was pretty amazing to
watch
right up close and we're just beginning
to understand it we're barely beginning
to understand it by the time i got
out of grad school we discovered an
entirely new class of
small rna genes that we didn't even know
existed that turned out to be really
important for epigenetics and control of
gene expression
so you know people want to know well how
do you generate all this diversity so
fast
and i think how do you generate
diversity at all how do you even make
features of an organism we're barely
able to answer those kinds of questions
right now and so
how do you make it different well i
don't think it's going to be that hard
so all you're talking about is there's
some environmental things and other
factors we don't really know exactly how
but it's possible
for all that diversity to happen rather
quickly absolutely it's totally possible
to have it happen really fast now you
mentioned the term epigenetics what is
that
epigenetic so yeah so you have your
genes
which are the things that make physical
parts
of your cells epigenetics
is the stuff that controls how the genes
make the physical parts of your cells
because you don't want all your genes on
all at once that'll give you cancer
that's bad
so you've got to have some sort of
control some sort of way of making sure
that the right things get made at the
right time
that's what epigenetics is all about so
it's kind of like a super
controlling factor over all of this
potential we were talking and it
controls
as much maybe even more of inheritance
from one organism to another when they
have babies
as the actual genes themselves there's
already a cell there that we call the
zygote once the egg has been fertilized
that has a bunch of epigenetic stuff
already in it
that's going to guide and direct how the
genes are expressed to build a new
organism
it seems like this whole genetic thing
is like we're just
touching the surface of something
amazingly deep and powerful
underneath is that that's exactly right
we are we're
on the brink and i love the idea of more
christians
becoming involved in this kind of
research and learning more about
the genome because to be on the cutting
edge of understanding
where all these traits and features are
coming from that's going to be
you know next generation creationism
right there it's a level of
complexity that's just much bigger than
just the simplistic ideas that we have
we think
we're the ones that are breeding all
these things you know and making all
these different dogs
no no we're expressing things that have
been built into that
system from the start yeah how far can
we go with that todd
that is an excellent question and to
really understand that we got to go look
that at the cat that isn't really a cat
the meerkat
is right around the corner here yeah
that's not a cat let's go check him out
i have to hate to lead you guys
so the cats that aren't cats the most
popular part of the zoo right
so they don't even look like cats they
look more like little weasels or
something
and i've made a work effort over the
years doing a lot of research
trying to understand the similarity of
these things to cats and i can show
quantitatively using all sorts of fancy
mathematics that these things are
very distinct from cats and i would
interpret
that as something i call discontinuity
there's a there's a difference between
cats on the one hand and meerkats on the
other hand
um so they are not the members of the
same created kind
they're not really related at all
they're separate creations that god made
in their own separate sort of kind so
are you saying that we couldn't take a
meer cat and breed it with a real cat
and get something in between no you
could not make them cat meerkat hybrid
no they're definitely is that that
discontinuity you're talking about that
is the discontinuity that i'm talking
about they are separate created kinds
you're not going to cross them you're
not going to you know
breed meerkats to look more like lions
it's not going to happen
they're different does that happen
across all kinds in
absolutely kinds are separate kinds are
distinct
they're cute and they're adorable
