If even the splitting of mammalian germ cells is not certain… maybe the 21st century would be better suited to questions in science than answers. It’s easier to get good answers when we have enough knowledge to get the questions right.
Maybe you didn’t even know they were out there but the hidden camera catches them.

Now, will those remains bolster textbook Darwinism or help sink it? Or in-between? We shall see.
