Precisely. All that stuff factors into evolution, regardless of whether it's genetic or not. The non-genetic nature of the "dino-killer" asteroid does not make the ascendance of small mammals any less of an evolutionary event.Shroom Man 777 wrote:But those advantages don't have anything to do at all with the genetic characteristics of the particular organisms. It's more like how creature A happened to be inhabiting a land rich in food sources, while creature B happened to get wiped out by an asteroid. I guess they can influence evolution because they are more like extrinsic environmental factors, but these are hardly hereditary genetic attributes that get passed down from generation after generation. So they're part of evolution, but just a different part from what Night_stalker thinks?
Night_stalker has a eugenicist's view of evolution, whereby it must always select for "superior" genetics.
Let's use an example: let's rewind the clock to my 20th birthday and assume I've been drafted along with some other guy; let's just call him Joe. Now let's say G.I. Joe is bigger than me, stronger than me, faster than me, and speaks three languages. He gets selected for Special Forces training, and assigned to very dangerous missions. Meanwhile, although I'm a reasonably fit physical specimen in most ways, I am near-sighted and flat-footed, but I'm good with math. My combination of strengths and weaknesses means that I get assigned to artillery. Which one of us is most likely to survive the war, go home, get married, and have kids? Does that mean I had superior genetics?
