Dear Panda’s Thumb crew:
I’m not a scientist, I’m a retired history teacher with a masters in
that field.
I’m not writing because I have any agendas. I’m trying to get my
questions answered and I’m having trouble doing it since I don’t know
any evolutionary biologists whom I could ask. Those I have written to
do not reply. I’m asking for the perspective of an evolutionary
biologist who might answer a student with questions who is not hostile
to evolutionary biology.
If you don’t have the time to reply, or don’t want to, please write me
and tell me that.
Here are my questions about macroevolution. My goal is to understand
how scientists explain how macro-evolution works in a real life
situation, in this case between reptiles evolving into birds, since this
is postulated as occurring:
*Reptiles Birds*
Lay eggs lay eggs
fly fly
have feathers? have feathers
cold blooded? warm blooded
Would being cold blooded show up in the fossil record? If not, how and
why would a reptile adapt over millions of years into warm-blooded? How
would anyone know whether a feathered reptile was now a bird if one
is/may be cold blooded and one is warm blooded? Where is the proof?
Same topic different question: We know that horses and donkeys can
interbreed to produce a mule, which is sterile. Using this explanation
for cross breeding, how does that fit with macroevolution? In other
words, could a flying, feathered semi-reptile mate with a full bird (or
any other combination), and not be sterile? Even over millions of years,
since there would be no progeny and the variant would die.
Third question: If a reptile/bird evolved, wouldn’t it also need a
reptile/bird to mate with to carry on the new species? If one, a male,
for instance evolved, and no female evolved at the same time and in the
same place, wouldn’t that end the cycle of macroevolution?
Thank you for your time.
Sincerely,
