Oh, sure. I was taught that in high school back in the 1950s. But frankly, it doesn’t make sense. Grow an eyeball, with an iris and a lense and all the rest of it?
And when it came to growing wings, I remember our textbook cited flying squirrels as a kind of intermediary stage. Sorry, it still doesn’t compute. Changing your front legs into wings over the course of thousands of years would be incredibly disadvantageous to all those poor intermediary creatures. They never would have survived.
Sorry Cicero. I thought the sarcasm in my post to you would be self-evident. I agree with you.
