Natural selection/survival of the fittest/adaptation is a fact. It can be observed within a few generations of a species. Evolution on the other hand, the idea that through adaptation a species can become an entirely different species, seems rather weak to me. Where is the solid evidence? Where are the missing links in the fossil records? What about fittness factors? If we separate adaptation and evolution into 2 theories how solid is evolution? Does proof of adaptation audomatically prove evolution?

Ok...suppose that people could get superpowers by altering their DNA structure before birth....but what about already born people (i.e. you and me) ?

Is it possible to rewrite an already written strand of DNA?

Is this the 'canary in a coal mine', potentially?
It strikes me a very, very strange, that the media abandoned this story as a headline issue.
I saw a story on how it is far, far worse in Malaysia, and now I can't find it.
Is this true?

I know how the Biology behind getting brown eyes works, but here's what Im trying to figure out, how far down the lines can blue eyes be passed down. Heres the story, I have brown eyes my husband is green - and our baby is crystal blue. I will give you some background info and tell me if you can find this at all to be possible..

Myself brown
My mother brown
My father brown
Maternal Grandparents brown
Paternal Grandparents brown
Great maternal Grandparents unknown
Great paternal Grandparents male:brown female: blue


Husband carries a blue gene ( father mother both blue, he's green)

How can I have given my son a blue gene - can it be carred down from my father grandmother ( my great grandmother) and what are the odds?

Thanks!
