| Quote | Wow. You really don't know shit about evolution do you. And that's a common creationist tactic known as a 'strawman'. You can't attack the argument that your opponent makes, so you make up an argument and attack that instead.
Now, listen very carefully. Individuals don't evolve. Say it with me. Individuals don't evolve.
POPULATIONS evolve. |
OK....Individuals don't evolve...individuals don't evolve...but I have a question:
How do populations evolve without the individuals within it ALSO evolving???? |
Well, yet another proof that you don't know what evolution means.
Individuals don't evolve. They develop according to the genetic material they inherited from their parents. If their own genetic material happens to experience a mutation during their lifetime - too late for them, although not too late for their children. If that mutation is harmless or beneficial given the environment at that time, it has a good chance to survive in and with the descendants.
In fact this is a verrrry much simplified explanation, I hope my learned friends will correct me if I made mistakes. |
OK, so please riddle me this.......a population speciates (that means evolves)....yet, I can choose to pick an individual within that population, examine that individual and it would NOT have speciated? Then if I examine every individual within that population and none have speciated, how can it be said that the population speciated?
LOL...You guys simply aren't making sense.... |
Because you aren't listening...
speciation does not equal evolution.
Sigh, let's try again.
When I was born, the human race evolved. This occurred because (among other things), the number of B blood type alleles increased by one and the number of A blood type alleles increased by one in the entire human population.
The frequency of the A allele and the B allele changed in the population.
That's evolution.
When I die, the frequency of alleles will change again (minus 1 A and minus 1 B). When my child was born, the frequency of B alleles and the frequency of O alleles changed as well. That is what evolution is in the strictest sense.
O is the most common blood type allele. But let's say that you have a small population of people, who, for whatever reason, leave the Earth to setup a new population of humans. Now, because of the difficulty of spaceflight, from now until some future time, we have two SEPARATE populations of humans. But the colony population was a little weird. For whatever reason, that population has no type "O" blood alleles. Call it random chance, call it bias against "O" blood types, whatever.
This is called the founder effect. The type "O" allele doesn't exist in the new population of humans.
Now, on the Earth, "O" becomes more and more common. Over time, the A and B blood types disappear entirely. Statistically unlikely, but I'm trying to teach you things here. So, we have a population of humans with only type O blood and another population without type O alleles.
Now, let's say that there is some difficulty in mating between O people and A or B people. Something similar to the RH factor (which can be treated medically now, but caused a lot of infant (and others) deaths before SCIENCE figured it out).
So, we have these two populations that, because of biochemical incompatibility, cannot interbreed anymore. NOW, we have another species of human.
Evolution does not determine that new species arise. Evolution is not dependent on new species arising. However, new species is an artifact of changes in the allele frequency in the population, especially when you get two populations of the same species that (for whatever reason) have breeding issues.
What I just described is allopatric speciation. There are other forms of speciation.
