A chicken is an egg's way of making another egg. I guess I’m just being dense here, Darby, and I apologise. That just seems to border on existentialism and I never understood that either. It's not an infinite grab-bag of possibilities that would allow a sponge to be a pear tree if only certain ones...

Well, I'd give you seven out of ten for the only question you've ventured an answer for. An allopolyploid is a hybrid with its sets of chromosomes being derived from different species. An autopolyploid derives its chromosome set from a single parent species. So, with more to work with, the chances o...

I was hoping to get some reply; in particular a blistering paragraph or two that would tear my hy...

Flawed theory?

Evolution is a process measured in millions of years; just how many new species were you expecting to have popped up in the few hundred years of science notation? However, you need go no further than pathogens that have evolved resistance to antibiotics and insects to insecticides and weeds to weedi...

A Monkey's Uncle

It has been reported recently that the time-difference between the chimpanzee and us splitting from a common ancestor is closer by a few million years than previously thought. Other apes, gorilla and the Orang, went their separate way several millions of years earlier still. The chimpanzee is, we ar...
