How do I answer this rebuttal?
« on: June 13, 2012, 03:45:29 PM »
Talking to a theist/family friend about the evolution of giraffes.  He contends that natural selection doesn't apply to the giraffe neck, because giraffes with taller necks can eat the leaves at the top of the trees and giraffes with shorter necks can eat leaves closer to the ground, thereby occupying different ecological niches.  Can somebody help me here?

Random chance. Taller giraffes bred while the shorter ones didn't. Or maybe the shorter ones were hunted down because they weren't as quick or intimidating.
The truth is absolute. Life forms are specks of specks (...) of specks of dust in the universe.
Why settle for normal, when you can be so much more? Why settle for something, when you can have everything?

Or other species eat the lower branches. The taller the giraffe, the more food they have available that other herbivores can't reach. Otherwise, a short-necked giraffe is competing with reeboks and other species that can stand on their hind legs and reach to that mid-height level.
If we ever travel thousands of light years to a planet inhabited by intelligent life, let's just make patterns in their crops and leave.

Benny;  I might be a dummy because I do not understand the giraffe problem. Of course to hell a short necked one eats leaves from the lower branches. What can that possibly have to do with the ecological or evolutionary propositions?  I mean Shaquille O'neal can eat from the top of the tree if he wants to. Whereas I am a much shorter person and I eat from the more accessable lower branches.  Soooo?

The guys giraffe argument is so sorrowfully feeble that it does not deserve a rebuttal.

BTW, if your family friend's purpose is to "disprove" evolution by showing that one single species out of the hundreds of million that we know of didn't evolve, he's probably better off with sharks.

Ask your friend why aren't there any short-necked giraffes.
Extraordinary claims of the bible don't even have ordinary evidence.

Kids aren't paying attention most of the time in science classes so it seems silly to get worked up over ID being taught in schools.

Another problem is that there's no Law to stop the longer-necked giraffes eating from the lower branches as well.

This should work.  Thanks, guys, and Darwins to you both.
