and wholphins?
What next?
Crazy
mixed-up animals
what do they tell us?
They seem to defy man-made classification systems
but what about the created kinds in Genesis?

Creation Ex Nihilo 22(3):2833
If we can cross-breed a zebra and a horse (to produce
a zorse), a lion and a tiger (a liger or tigon), or
a (false) killer whale and a dolphin (a wholphin), what does this
tell us about the original kinds of animals that God created?
The Bible tells us in Genesis chapter 1 that God created
plants to produce seed after their kind
(vv. 11, 12). God also created the animals to reproduce after
their kind (vv. 20, 24, 25). After
their/its kind is repeated
ten times in Genesis 1, giving emphasis to the principle. And we
take it for granted. When we plant a tomato seed, we dont
expect to see a geranium pop up out of the ground. Nor do we expect
that our dog will give birth to kittens or that Aunt Betty, who
is expecting, will bring home a chimpanzee baby from hospital! Our
everyday experience confirms the truth of the Bible that things
produce offspring true to their kind.
But what is a created kind? And what organisms
today represent the kinds God created in the beginning? The creationist
scientist, Carolus Linnaeus (17071778), the founder of the
science of taxonomy, tried to determine the created kinds.
He defined a species as a group of organisms that could
interbreed among themselves, but not with another group, akin to
the Genesis concept (see the box about Linnaeus below).
Finding
the created kinds
From Genesis 1, the ability to produce offspring,
i.e. to breed with one another, defines the original created kinds.
Linnaeus recognised this, but named many species without
any breeding experiments, on the basis of such things as flower
characteristics. In his mature years he did extensive hybridization
(cross-breeding) experiments and realised that his species
concept was too narrow for the species to be considered as created
kinds; he thought that the genus perhaps corresponded better with
the created kind.
Box
A: Linnaeus and the classification system
Linnaeus established the two-part naming
system of genus and species. For example, he called wheat
Triticum aestivum, which means in Latin, summer
wheat. Such scientific names are normally
italicised, with the genus beginning with a capital. When
used in scientific works, the names are followed by the
abbreviated name of the scientist responsible for the name.
When L. follows a name, this shows that Linnaeus
first applied the name. For example, the name for maize
or corn is Zea mays L. Linnaeus named
many plants and animals.
There can be one or many species in a genus,
so genus is a higher level of classification. Linnaeus also
developed the idea of grouping genera (plural of genus)
within higher groupings he called orders, and the orders
within classes. Linnaeus opposed the pre-Darwin evolutionary
ideas of his day, pointing out that life was not a continuum,
or a great chain of being, an ancient pagan
Greek idea. He could classify things, usually into neat
groups, because of the lack of transitional forms.
Later, other levels of classification were
added so that today we have species, genus, family, order,
class, phylum and kingdom (see the diagram below). Sometimes
other levels are added, such as subfamily and subphylum.
|
Even today, creationists are often misrepresented
as believing that God created all the species we have today,
just like they are today, in the beginning. This is called fixity
of species. The Bible does not teach this. Nevertheless, university
professors often show students that a new species has
arisen in ferment flies, for example, and then claim that this disproves
the Genesis account of creation. Darwin made this very mistake when
he studied the finches and tortoises on the Galápagos islands
(He also erred in assuming that creation implied that each
organism was made where it is now found; but from the Bible it is
clear that todays land-dwelling vertebrates migrated to their
present locations after the Flood.)
If two animals or two plants can hybridize (at least
enough to produce a truly fertilized egg), then they must belong
to (i.e. have descended from) the same original created kind. If
the hybridizing species are from different genera in a family, it
suggests that the whole family might have come from the one created
kind. If the genera are in different families within an order, it
suggests that maybe the whole order may have derived from the original
created kind.
On the other hand, if two species will not hybridize,
it does not necessarily prove that they are not originally from
the same kind. We all know of couples who cannot have children,
but this does not mean they are separate species!
In the case of three species, A, B and C, if A and
B can each hybridize with C, then it suggests that all three are
of the same created kind whether or not A and B can hybridize
with each other. Breeding barriers can arise through such things
as mutations. For example, two forms of ferment flies (Drosophila)
produced offspring that could not breed with the parent species.
That is, they were a new biological species. This was
due to a slight chromosomal rearrangement, not any new genetic information.
The new species was indistinguishable from the parents
and obviously the same kind as the parents, since it came from them.
Following are some examples of hybrids that show that
the created kind is often at a higher level than the species, or
even the genus, named by taxonomists.
Mules,
zeedonks and zorses
Crossing a male ass (donkey Equus asinus)
and a horse (Equus caballus) produces a mule (the reverse
is called a hinny). Hybrids between zebras and horses (zorse) and
zebras and donkeys (zeedonk, zonkey, zebrass) also readily occur.

B: Zonkeys and Zorses'.. new animals but not new
kinds
|
Zonkeys are the result of a cross
between a Zebra and a Donkey' Tigger,
belongs to Camilla Muluotoga, from New Mexico in the
USA, and is the name she gave to a cross between a
Horse and a Zebra, known as a Zorse.

Some creationists have reasoned that because these
hybrids are sterile, the horse, ass and zebra must be separate created
kinds. However, not only does this go beyond the biblical text,
it is overwhelmingly likely that horses, asses and zebras (six species
of Equus) are the descendants of the one created kind
which left the Ark. Hybridization itself suggests this, not whether
the offspring are fertile or not. Infertility in offspring can be
due to rearrangements of chromosomes in the different species
changes such that the various species have the same DNA information
but the chromosomes of the different species no longer match up
properly to allow the offspring to be fertile. Such (non-evolutionary)
changes within a kind can cause sterility in hybrids.
Ligers
A male African lion (Panthera leo) and a female
tiger (Panthera tigris) can mate to produce a liger. The
reverse cross produces a tigon. Such crossing does not normally
happen in the wild because most lions live in Africa and most tigers
live in Asia. Also, lions and tigers just dont mix; they are
enemies in the wild. However, the Institute of Greatly Endangered
and Rare Species, Myrtle Beach, South Carolina (USA), raised
a lion and a tigress together. Arthur, the lion, and Ayla, the tigress,
became good friends and bred to produce Samson and Sudan, two huge
male ligers. Samson (pictured at top) stands 3.7 m (12 feet) tall
on his hind legs, weighs 500 kg (1,100 lbs) and can run at 80 km/hr
(50 mph).
Lions and tigers belong to the same genus, Panthera,
along with the jaguar, leopard and snow leopard, in the subfamily
Felinae. This subfamily also contains the genus Felis, which
includes the mountain lion and numerous species of smaller cats,
including the domestic cat. The cheetah, genus Acinonyx,
belongs to a different subfamily. Thus the genera
Panthera, Felis and Acinonyx may represent descendants
of three original created cat kinds, or maybe two: Panthera-Felis
and Acinonyx, or even one cat kind. The extinct sabre-tooth
tiger may have been a different created kind (see diagram below).

THE
CREATED CAT KIND
|
| Possible history of cats
since creation. Speciation (based on pre-existing created
genetic information) probably occurred faster after
the Flood due to greater environmental pressures, isolation
due to migration of small populations, and many unoccupied
ecological niches. |
|
The Panthera cats lack a hyoid bone at the
back of the tongue, compared to Felis. Acinonyx has
the hyoid, but lacks the ability to retract its claws. So the differences
between the cats could have arisen through loss of genetic information
due to mutations (loss of the bone; loss of claw retraction). Note
that this has nothing to do with molecules-to-man evolution, which
requires the addition of new information, not loss
of information (which is to be expected in a fallen world as things
tend to fall apart).
Kekaimalu
the wholphin
In 1985, Hawaiis Sea Life Park reported the
birth of a baby from the mating of a male false killer whale (Pseudorca
crassidens) and a female bottlenose dolphin (Tursiops truncatus).
The birth surprised the park staff, as the parents are rather different
in appearance. Here we have a hybrid between different genera in
the same family, Delphinidae (dolphins and killer whales).
Since the offspring in this case are fertile (Kekaimalu has since
given birth to a baby wholphin), these two genera are really, by
definition, a single polytypic biological species.2 Other
genera in the group are much more alike than the two that produced
the offspring in Hawaii, which suggests that the 12 living genera
might have all descended from the original created kind.
Sea Life Park (Hawaii) The worlds only
wholphin
false killer whale/dolphin cross
False killer whales (pseudorcas) and bottlenose
dolphins are each from a different genus. Man-made classification
systems were thrown into confusion when these two creatures
mated and produced a live offspring' The wholphin,
named Kekaimalu.She now swims with her (smaller) mother,
a bottlenose dolphin.
This suggests that all killer whales and
dolphins, which are all in the same family, are the one
created kind.
This wholphins size, shape and colour
are right in between those of her parents. She has 66 teeth
an average between pseudorcas (44 teeth)
and bottlenose dolphins (88).
Kekaimalu has since mated with a dolphin
to produce a live baby.

Rama
the cama
Veterinarians in the United Arab Emirates successfully
cross-bred a camel and a llama. The cama, named Rama,
has the cloven hooves of a llama and the short ears and tail of
a camel. The scientists hope to combine the best qualities of both
into the one animal the superior fleece and calmer temperament
of the llama with the larger size of the camel.
Genae
the hybrid snake
Genae resulted from a cross between an
albino corn snake (Elaphe guttata) and an albino king
snake (Lampropeltis triangulum) in a reptile park
in California. Apparently, this particular intergeneric
hybrid is fertile. Genae is almost four years old and already 1.4
m (4½ ft) long. The parent snakes belong to the same snake
family, Colubridae; the success of this hybrid suggests that the
many species and genera of snakes in this family today could have
all originally come from the same created kind.
Other
hybrids
With the cattle kind, seven species of the genus Bos
hybridize, but so also does the North American buffalo, Bison
bison, with Bos, to produce a cattalo. Here
the whole family of cattle-type creatures, Bovidae, probably
came from an original created cattle kind which was on the Ark.
Plant breeders have bred some agriculturally important
plants by hybridizing different species and even genera. For example,
triticale, a grain crop, came from a cross of wheat (Triticum)
and barley (Secale), another fertile hybrid between genera.
During my years as a research scientist for the government
in Australia, I helped create a hybrid of the delicious fruit species
lychee (Litchi chinensis) and longan (Dimocarpus longana),
which both belong to the same family. I also studied
the hybrids of six species of the custard apple family, Annonaceae.
Each of these two family groupings, recognised by botanists today,
probably represents the original created kinds.
God created all kinds, or basic types, of creatures
and plants with the ability to produce variety in their offspring.
These varieties come from recombinations of the existing genetic
information created in the beginning, through the marvellous reproductive
method created by God. Since the Fall (Genesis 3), some variations
also occurred through degenerative changes caused by mutations (e.g.
loss of wing size in the cormorants of the Galápagos Islands).
The variations allow for the descendants of the created
kinds to adapt to different environments and fill the earth,
as God commanded. If genera represent the created kinds, then Noah
took less than 20,000 land animals on the Ark; far fewer if kinds
occasionally gave rise to families. From these kinds came many daughter
species, which generally each have less information (and are
thus more specialized) than the parent population on the Ark. Properly
understood, adaptation by natural selection (which gets rid of information)
does not involve the addition of new complex DNA information. Thus,
students should not be taught that it demonstrates evolution
happening, as if it showed the process by which fish could
eventually turn into people.
Understanding what God has told us in Genesis provides
a sound foundation for thinking about the classification of living
things, as Linnaeus found, and how the great diversity we see today
has come about.
A geep?
No a chimera
Despite the fact that the geep has
both sheep and goat in its parentage, and shares the characteristics
of both species, it is not a hybrid. It is a chimera,
formed by mixing the (fertilized) embryo cells of two different
species.
The DNA in each adult cell (including sex
cells) is thus either fully sheep or fully goat hence
the patches of either thin white goat fur or thick sheeps
wool. Thus also, any offspring will either be all sheep
or all goat. This artificial manipulation is very different
from the situation where two animals of the same kind (but
different species) mate producing live offspring.

Biological species is often used today
to refer to a group of organisms that can interbreed to produce
fertile offspring. It does not always correlate with the taxonomic
species. Note that the kinds would originally
have met the criterion for each being a separate biological
species, since they did not interbreed with any other kind.
