Epigenetics - the ability to switch certain genes on and off without changing the genetic information (like commenting out certain lines of code) based on environmental cues.
- zasdffaa 4y agoI'm aware of epigenetics via methylation
- pazimzadeh 4y agoWell there's your mechanism. I don't understand "Why pick the former when the latter works." No one is picking anything, it's all happening simultaneously. An epigenetic solution would reduce selective pressure for a genetic solution, theoretically.
- zasdffaa 4y agoBecause the former mechanism, for lamarkism, wasn't given, and Some kind of "genetic intelligence" is just a vacuous proposition, so why raise it. Your mention of epigenetics was a sensible suggestion in that at least it's known to happen (although whether it can control skin colouring is another matter)
- pazimzadeh 4y agoI would think so. https://en.wikipedia.org/wiki/Epigenetics_and_melanoma https://en.wikipedia.org/wiki/Epigenetics_and_melanoma Maybe the black frogs are at higher risk of melanoma. Nothing is ever free..
- zasdffaa 4y agoJaysus! Is there anything wikipedia doesn't have a detailed article on. (checks page history, nope it's been around a while, I guess you didn't just write it to win this one) Good catch anyway!
