The late Farrell Till said that the koala has a very narrow diet; infact some are so specialized that they not only can't eat anything but eucalyptus leaves but they also cannot eat from eucalyptus trees outside their local eucalyptus woods (or something like that).

Could a bunch of random DNA mutations explain the koala diet. I'm asking if the "neo-Darwinian" theory (using Gregor Mendel theory to supplement Darmin's theory) really does best explain this situation. Wouldn't the data suggest that the most logical conclusion is that this narrow diet was acquired by behavior of a koala during his/her life and somehow (by say epigenetic means?) this trait got passed down into succeeding offspring and it got locked into the animals DNA later down the generational tree?
Humans used to not be able to digest cow milk until around 6,000 to 10,000 years ago. Now 96% of Sweedish people can digest cow milk. Random DNA mutations brought this about?
Perhaps Lamark might have been onto something. Or no?
Edited by Admin, : Change title from "Does the narrow quala diet back up Lamark's 1809 theory?" and fix spelling.

Changing the Title
Hi LamarkNewAge,
Before I promote your topic (your other topic was promoted to the Coffee House forum and can be found at RationalWiki.org site and Operation Northwoods) I'm going to change the title so that it mentions epigenetics.
