Peanut Butter Disproves Evolution!!

Somebody with the relevant information needs to steer laptoppop to one of those species where there is no loss of fitness accompanying resistance.

Yes, please.

 

[hithesh]

Note the qualifier.

I see.

 

[hithesh]

Yes, please.

Well the entire transition from single cell, to multi-cell organisms, is the product of positive mutation.

Your current ability to see, you ability to hear is a product of "positive" mutations.

 

[random_guy]

Yes, please.

Well, I gave examples. Gene amplification, it's not the "growing a new arm" type mutation, but increased protein production is still a valid mutation.

This whole "beneficial mutation" thing seems quite a fair bit overrated to me. Hithesh's example of multicellularity is instructive. Scientists have uncovered possible mutations that cause unicellular organisms to clump together and aggregate. But is that a beneficial mutation? From the point of view of the organism, yes. From the point of view of the gene, maybe. But in terms of the cells, multicellularity is pretty much the end of the road for most of them. Look at our human body. Of the trillions of cells in the body, only a thousand of them will get remotely any chance to pass their genes on to the next generation of humans. From an evolutionary perspective it sucks to be a somatic cell. And yet multicellularity has given us all kinds of exotic and interesting lifeforms - out of a mutation that, in the wrong context, sounds more like a death warrant than anything else.
