Your claim evolution only happens on an individual basis is false.Quote from jcl:
Well, I suggest that you then google for the words "punctuated equilibrium".
This is not how evolution works. Evolution is indeed driven by competitive advantage, but among individuals, not among species. You would have evolution even if only one single species existed. Evolution causes optimal adaption to the environment, until a point where the overall fitness has reached a local maximum. Then you have equilibrium. It's a rather simple, but highly successful concept, and works in many different areas, even in engineering.
Quote from jcl:
Those species have reached an equilibrium with their environment. Put them in a different environment and they will change.
Quote from peilthetraveler:
Explain this. The coelacanth is a fish that according to science has not changed in 400 million years. 300 million years ago the supercontinent Pangea was starting to break up. Obviously the worlds environment changed in the time that fish has been around in every corner of the world, so your argument doesnt hold water.
If you want to ignore that, then answer this. How does Adenine, Thymine, Cytosine and Guanine (DNA) "know" they need to start rearranging themselves to suit their environment. Or better yet...why does that DNA know it needs to create a host? Does it believe living longer is better than dying young? You are going into the realm of conscious thought now...
Quote from jem:
I thought there was little debate. I thought everyone acknowledged there are gaps in the genealogies accept a few born agains.

I said that evolution is driven by individual competition, not competition between species. The lion does not compete with the antelope, it competes with other lions. Evolution generates new species when a population becomes separated in different environments or different ecological niches.Quote from Mercor:
Your claim evolution only happens on an individual basis is false.
This is the Madagascar effect. Individual or localize evolution is really one basis for new species.
It is not a theory against, it is a supplement of Darwinâs evolution theory. Darwin had not the information that we have now; he described evolution without knowing anything of its mechanism. We only know the evolution mechanism since the 1960s, when DNA based reproduction was discovered.Quote from Mercor:
Punctuated equilibrium theory has more to do with evolution rate of change as a species, it is a theory against Darwinâs gradual evolution theory.
The undersea environment has not changed much in the past 400 million years. That's why sea animals evolve much slower than land animals. Chondrichthyes, the group where sharks belong to, also exists since about 400 million years.Quote from peilthetraveler:

Evolution does not require consciously thinking DNA. It only requires frequent changes in the base pair arrangement, called mutations. If the change causes better adaption, it becomes permanent due to the higher reproduction rate of the individual. That's evolution in a nutshell.Quote from peilthetraveler:
