It is possible to find a crossbreed between a lion and a tiger, they are called Ligers or Tigons. I bullsh*t thee not - http://www.lairweb.org.nz/tiger/ligers.html

If the same were to happen with cats and dogs, would they be called dats or cogs? And would the babies be called cuppies or dittens (awww how cute!)

Would you feed them tins of cuppy cog or ditten dat (as opposed to kitty kat for cats)?

I understand how mutation happens, what I don't understand is how it's propagated to the next generation. Let's say I have a gamma particle that hits a base pair in one of the genes in a skin cell. The cell mechanics repair the gene with a mistake (a mutation). How does that cell mutation get passed to my offspring? Wouldn't the mutation have to happen in the fertilized egg, before it splits, for it to be passed to my offspring?

I mean, they are always at it, it seems that if you put a breeding pair together you'll get hundreds within a few months, so if you seperated newly born rabbits, and brought them back together, will they know that they are related and not mate with each other, or will theu be incestious?

"Intelligent Design is dead. It just hasn't fallen over yet." The overwhelming majority of scientists support the massive evidence that is evolution . . and to skeptics inability to disprove the theory.

Why do people continue to persist with Intelligent Design? WHY?!?
