Quote from: Solomon Zorn on June 22, 2014, 07:15:50 AMI saw this report on CBS News the other day, and I thought of posting it. Possibly a beneficial human mutation, found in a group of Amish, that's giving us insight into heart disease.http://www.cbsnews.com/videos/preventing-heart-attacks-new-study-says-gene-mutation-can-ward-off-threat/It got me to wondering just how often such positive mutations take place.
Quote from: Solomon Zorn on June 22, 2014, 09:36:54 AMForgive me for being an uneducated hick, but is it possible that evolution on a macro scale takes a similar growth curve to an individual life form, going from the simple to the complex, until a maturity point is reached?I would define a maturity point as when further changes become detrimental, simply by being random changes in something that has already become a complex system. Mutation would therefore no longer be as strong a positive force for change as it might once have been to a lower life form, because almost any change, at this point, is going to be bad.
Quote from: Solomon Zorn on June 22, 2014, 09:36:54 AMEvolution of life on Earth must be taking some kind of predictable curve, and it seems to me that we are at a leveling off point for random genetic mutation. The way I see it, human evolution is now external, taking an obvious form in how humans interact with with their environment through technological advances, and taking a more subtle path in the growth of human interaction with each other.
QuoteNot really as that would imply evolution has a direction and an ultimate endpoint.
Quote from: Solomon Zorn on June 22, 2014, 10:44:54 AMNot any kind of intentional endpoint am I suggesting, just a slowing down of the more rapid change that may have taken place in ages past. A relative leveling off. Perhaps most of the potentially beneficial mutations have already occurred, like developing limbs. Beneficial changes may have slowed down because the system is already so complex that only subtle changes can be beneficial. I mean, how often do we see beneficial mutation occurring today in higher life forms? I think it's more frequent in simpler forms. To say it's predictable curve may be taking it too far.But like I said, I'm an uneducated hick just tossing out an idea.
Quote from: stromboli on June 22, 2014, 10:47:07 AMQuestion; is this diet based or some other factor that could cause this? The Amish live a life centered around a very specific food supply and have done so for generations. So is the diet the driver or some other factor? I would think their lifestyle would tend to preclude heart attacks, being active people.
