how bizarre. I was thinking about this exact same question about a week ago, and i was going to post the topic here! I have also wondered if there was an answer to Shawshank's question about the "spark". I was asking my wife how over time a rabbit's fur knew to be white in the winter and brown in the summer. it's not a consious decision, obviously, so how, and maybe more importantly, why, did this happen?Gimli 1993

Shawshank wrote:A bee not having a stinger, and then having one, is a definite upgrade. It is more than a mutation, because that appendage has a specific purpose with a unique design that is geared to protect the bee from a specific predator. It's a crazy world we live in.
Did bees ever exist without stingers? Or is that just an assumption?0 -
The simplest answer - competition causes evolution.The only people we should try to get even with...
...are those who've helped us.

this
and it's not an all of a sudden kind of thing
it took multiple generations of bees to adapt the stinger
i know i promised i'd stay off the train but
it's evolution babyhaffajappa wrote:Don't think of it like a giraffe grew a longer neck, that's not what the evolution theory is
Its survival of the fittest...
natural selection.
The giraffes with longer necks could reach the food, the ones with shorter necks couldn't fend. As time goes on those who can survive in the environment prosper, those who can't die out. Eventually the gene pool becomes specifically the species with certain traits that allow them to survive in their habitat.
Not sure on the specifics of the honey bee, but that's evolution 101, them's the basics.
Oh, and what thoughts_arrive said.fuck 'em if they can't take a joke

is there proof positive that there is actually evolution or is every species of it's own kind ?
