correct me if I am wrong, but didn't Darwin believe that learned
behavior added to evolution? certain instincts come from DNA who is to say that learned behavior could not be added to the DNA in sperm and eggs? -- Dale |

In article , Dale wrote: correct me if I am wrong, but didn't Darwin believe that learned behavior added to evolution? Sigh. I really should not be responding to an off-topic post, but... Darwin wrote about natural selection of inherited characteristics. (Actually, he wrote about a lot of things, including the succession process by which bare rock eventually becomes soil bearing vegetation. Back then, a "naturalist" studied everything.) The concept of "evolution" was already being batted around in both the natural sciences and in the popular imagination long before Darwin. What Darwin did was propose a mechanism by which it might happen, backed up by tons of observational data of speciation in currently living fauna. certain instincts come from DNA Which would make them inheritable traits, and therefore subject to natural selection. who is to say that learned behavior could not be added to the DNA in sperm and eggs? You have evidence of a workable "write to DNA" mechanism? That is an extraordinary claim requiring extraordinary proof. The teaching of young by parents is a more demonstratable method for transfering learned behavior from one generation to the next, at least for those species that have "parenting". In this case, the inheritable trait that might be favored by natural selection is a tendency for parents to spend time showing their young how to do things, and/or a tendency for young to imitate what they see their parents doing. More time consuming that simply inheriting skills, but much more flexible. For example, bears in Yellowstone have been observed teaching their cubs preferred methods for tearing open different models of cars; these skills cannot be more than a few decades old, and it would have taken thousands of generations for them to evolve genetically. -- Please reply to: | "Evolution is a theory that accounts pciszek at panix dot com | for variety, not superiority."
