why should they become faster? this does not make sense.[/quote]

how can it pass this information? via twitter? .. .
a dead organisms only influence on the system is, that it cant alter it anymore, by not being able to reprodude. but since the premise was, that it already has descendants, this point does not matter. the young zebra will not become faster, because its dead parent told it to outrun the lion. the biological premise is still the same.[/quote]
have to ask a genoligist about evolution stuff.. I was just say'n that's what that poster meant, hence the ?[/quote]
and thats why i wrote, that it does not make sense.
well my laymans opinion is that other future zebra learn through experience and that is somehow transmitted genetics through decendents the urge to run faster to survive. It's a situation where you have to look at the long haul, over generations not just one example of one Lion vs Zebra. LIke dogs can paddle instinctually when in water. The don't have to learn to swim, it's an automatic response.
I've read that human babies can swim at birth, but later sink like a rock, instinctual but not fully 'learned', or adaptation?
hows that?[/quote]

End of Quote.... I messed up the quoting there.. apparently.
The evolutionaly implications on a Zebra would be that Zebras who run faster will outrun the predators or prove to be harder to catch than their slower family members. This in turn meen that the lions will eat the slower zebras first and only the faster zebras will have progeny sharing the genetic profile of it's parrents who were fast enough to avoid getting eaten by the lions.
Evolution favors genetic benefits that allowws individuals to survive long enough to have ofspring and any abilities that helps them survive their early years so that that ofspring in turn can continue the cycle. Presumably it will be two "fast enough" individuals that will reproduce.
On the other hand evolution rarely cares about things that affect health or other problems beyonf the need to survive long enough to have ofspring or the ability to raise new copies of themselves. So in otherwords there is no benefit to lifing several years after your fertile lifespan, meening agediabetes, cancer and other problems arn't removed from the genetic pool since the individuals usualy manage to carry ofspring before those diseases kill you or criple you, leading to your death.
In otherwords, evolution favors reproductive capability but doesn't nessesarily perfect genetic herritage in other ways. It's usualy the most apparent physical attributes that are affected and considered.
