He did in the first edition.
You mean, in the first public incarnation of the idea of evolution, centuries ago?
Owkay. Even if he did, or even if he did in the 25th version - it doesn't really matter as it's a teeny weeny outdated by now.
It's not stability in the number of individuals that lead to change. It is near extinctions where few individuals survive.
No.
For example, the e-colli in lenski's experiment that evolved the ability to metabolize citrate, most definatly weren't under threat of extinction. At all.
This is exactly how we breed plants and animals; selection of a few individuals.
Ha. That's called
artificial selection and it is why in breeding programs, accomplishing evolutionary changes goes (or can go) much faster then in nature. Nature doesn't care about change. Nature cares about reproduction and survival. In artificial selection, we focus on a single trait, or a handfull of traits, and we completely zoom in on that - regardless of consequences.
This is why plenty of fruits and dogs are actually no longer able of natural reproduction - because of our selection for specific traits with no regards to other things which in nature wouldn't happen.
When we select on the basis of behavior then the species changes.
And the exact same happens when selection is done on the basis of survival and reproduction - which includes behavior and anatomical traits. You seem to forget that the environment in which species must survive is also ever-changing. Today it's for example, on average, cold in places where it used to be hot and vice versa.
Species living in those area's must necessarily adapt to such environmental changes. Another option for them is to migrate to places with similar climate - but at that point, they'll STILL be confronted with a change in environment... they'll move into territories with new natural enemies (or lack of them!), new pathogens, new insects, new diets,........
I have no clue how you can understand that (artificial) selection drives changes, but (natural) selection for some reason doesn't?
Why does it matter what the parameters of selection are? As long as there is selection, there is selection.... regardless of humans deciding the parameters of the "fitness test", or if it is the environment that does it.
The "theory" of evolution is approaching the reality and it is much different than Darwin already.
There's a lot that Darwin didn't know, sure. There are things he got wrong, sure.
But to say that what we know today is "much different" - that is just wrong.
The core of the matter is still pretty much identical: reproduction with modification followed by natural selection. Pretty much the entire field of inquiry can be summed up and simplified to those 7 words.
Darwin realised the core of the idea, smack on.
Genes drive behavior just like everything else in the individual. Life is conscious and individual just like change in species. Yet we can't even define consciousness and now days reality is determined by committee.
That made no sense to me at all.
No theory is without anomalies.
What anomaly is there in evolution theory, in your opinion?
The fact is that except in the lowest species no experiment has ever shown a gradual change in species as a result of "survival of the fittest".
