I know that there are many people debating if there is such thing as a "positive mutation." I have been researching this topic for only an hour for a class, and I have been able to learn only a few things, which seem to be opinions...
1.Mutations may have favorable traits but are there are never any completely positive mutations.
2.The traits of mutations may be favorable or unfavorable depending on the environment that the mutations have occurred in.
I was wondering if anyone would be willing to help me out by giving your opinions here. I would also love any examples of "positive mutations" if you believe there is such a thing, or if you don't tell me why there aren't pos. mutations!
So far I have gotten very vague information about sickle cell, Lactose tolerance, and Resistance to atherosclerosis.
I just started biology 3 weeks ago, so try to keep it simple for now!!
THANKS!!!!!!!
