I
get the concept that animals with similar features could be related
via a common ancestor. It's not an entirely unreasonable conclusion.
However, we also see similarities in animals that are not closely
related according to evolutionary theory. There's the example of
marsupial moles and placental moles. Marsupial mammals and placental
mammals supposedly split tens of millions of years ago. Marsupial/placental moles are not supposed to be as closely related as humans and chimps
are supposed to be yet I believe the different moles resemble each
other far more than humans and chimps do. If similarity is supposed
to be evidence for common descent, then why are the different moles
(who are far more distantly related) more similar than humans/chimps
(who are supposed to be more closely related)?
When
animals that aren't closely related resemble each other,
evolutionists say that it's the result of convergent evolution. They
say that form-follows-function and since both moles live in similar
environments, over “millions of years” of undirected mutation,
they evolved similar traits. The
Encyclopedia of Science put it this way,
“One
of the reasons that convergence happens is that some body structures
and shapes are simply the best biological solutions to basic problems
in physics.... Convergent animals may look alike but it is easy to
show that they are entirely different creatures with very unlike
ancestors – their resemblance in appearance is not due to close
relationship. The structures which give the resemblance often do not
develop from a common feature in an ancestor.”
That's
interesting. OK, it's not really that interesting; I mean to say
it's revealing. It's an example of evolutionists wanting to have it
both ways. Creationists have attempted to point out to evolutionists
that similarity is not necessarily evidence of common ancestry. To
demonstrate this, we sometimes point to similar created things as
examples. Evolutionists object saying it's not fair analogy to
compare living things with created things. However, in the case of
moles we see two living things that are similar and not closely
related. What's their objection now?
So
let me get this straight: similar features between creatures could be
due to common ancestry (as in humans and chimps) or not due to common
ancestry (as in marsupial/placental moles). Is that right? How
convenient that, either way, evolutionists still see it as evidence
for their theory! It seems to me that evolutionists already know
that similarities between creatures is not de
facto
evidence that they are closely related in an evolutionary sense.
We've been trying to tell them that for years! What I wonder is why
do they keep trotting out similarities between humans and chimps like
it's somehow proof
of something?
What
we're left with is a bifurcation: similarity is either the result of
common ancestry or convergent evolution. They stubbornly leave out
the third option – similarity is the result of design!
