Ok ...I didin´t think you would agree so here is another question:
Darwins theory states that a species is not infuenced by its environment in evolution (because this would include some "intention" behind evolution)
but rather the mutation gives the species an advantage in its environemnt and be superior to other species because of this.
So ..penguins can only stand on ice because they developed a system in which their arteiries and veins are entangled and thus cooling/warmig blood
coming from the heart/leading away from the heart so their feet/legs won´t freeze.
According to Darwin they must have developed this system per coincidence in a environment where they could survive without it and then have traveled
to the south pole afterwards because they were - by coincidence - able to survive there?
Wouldn´t it be much more logical if they had evolved there with this ability as response to their environment ?
I can think chain of events that would cause penguins.
Some species of bird, perhaps a duck, lived into a time of severe seasons. Lots to eat in the warm summer, living off fat alone in the frozen winter.
Only the ducks who put on alot of fat would make it through the winter.
After a while the climate became milder and there were lots more fat ducks, but there were also more predators. The new predators used to be omnivore
scavangers but fat ducks are easy to catch. The ducks who moved to colder parts of their neighborhood encounter fewer predators and continue to
Over the ages and Ice Ages the ducks who are born with advantages to the cold will have more offspring and also move to even colder climates until the
sum of all mutations has made them penguins.
I'm trying to impart that penguins weren't a target that DNA shot for, they are just the end result of many factors.
Evolution is more like a game than a puzzle. With a puzzle the end is fixed, with a game the end depends on what has preceded it.
