Two points: Evolution is directionless, not “upward”, and if there is a change in allele frequency due to environmental stresses, evolution has taken place. The author is wrong.

if there is a change in allele frequency due to environmental stresses, evolution has taken place.

That is the convenient definition of evolution, chosen specifically so that Evos can say "evolution happens all the time".

The important question is: can one species turn into another species? And so far, there is only speculation about that. There have been no observed cases.

When a definition doesn’t fit the evidence then change the defintion. It is always easy to prove “evolution” as long as the definition is always changing. Too bad Newton was so rigid as to define Force as a function of mass and momentum

[Hacklehead]

Considering that the classic definition of species is based on the inability to crossbreed, doing the test on organisms that reproduce asexually (by binary fission) makes no sense.

No fair, using actual science and logic in an argument on a "cretin" thread!/sarc



To mistrust science and deny the validity of the scientific method is to resign your job as a human. You'd better go look for work as a plant or wild animal.

Evolution is directionless, not “upward”

I think a more correct statement would be that science cannot see 'direction' or be used teleologically - since this can only be done outside science's necessary limitations.

Second, using the only example we have, our earth, evolution IS upward - matter, life, mind, intelligence, consciousness.
