Evolution

iirc the experiment was going on about 20 years before it happened.

The experiment could have been running for 16 centuries before the mutation trigger occurred (or never of course).

It was a few of mutations that added up not just one.

Apparently it took an extra 10k generations before it could do it from the original mutation.

you're right though is lucky as hell

That was painful to read there isn't an 'end' to evolution. We can observe it happening in bacteria because they have such a short lifespan and quick breeding.

He posted it already.

Still a very interesting read.

ah lol

Even if it it took 5000 years it would make perfect sense, that's nothing on a cosmic timescale.

Yeah I thought that was the one. Same original sample, separated and then allowed to run generational cycles to see if the samples began to deviate give the same environmental conditions.

And using macro-biology to explain the concept of evolution is never a good idea.

I was thinking more along the lines of them not needing to evolve anymore.
.

As their environment changes they will make lots of little changes still they will never stop evolving.

Idiot example for you. Say over the next 20 years, trees suddenly started to be twice as high as they are now. Giraffes could not evolve a longer neck in time and would lose one of their major food sources. Silly example I know but you get the point.

that's not necessarily true ,you never know that giraffes would die out, because essentially the reason giraffes have a longer neck is because of mutation. If all the trees were to suddenly become taller, there is a chance that there could be a gene mutation and a giraffe would be born with a much longer neck. This giraffe would be able to reach the food and thus survive. It would then pass this longer neck on to its children, and so other giraffes may die out, but the ones remaining would be from this giraffe which had a gene mutation and was born with a longer neck

I think he knows that but the fact that it is such a short space of time makes the right mutation so unlikely that it might as well be impossible
