The difference in that analogy is that life isn't spare parts.

Mammals all look quite similar in early fetus development. The forming cells are dictated what to turn into, based on the species. A small amount of changes in that cycle can produce new genes quite quickly.

Nothing earth shattering from what I read in your post. Genetic drift does seem to be a pervailing part in human evolution over the past little while, and I don't see that changing. Since the gene pool is the world over, there's a big range of genes. Even the next mass extinction may not kill off hu...

Not sure where I made any name calling or insults. Plus, it wasn't just one spelling error in his post. The diseases I mentioned are the result of a beneficial mutation. I'm not as aware of what the heterozygote of the Tay Sachs gene gives, but if you have one Sickle Cell Anemia gene and one normal ...

Wrong. Evolution is the adaptation of a creature to it's environment that ensures it's furthered existance Wrong? Tell that to PhDs. Evolution defined has absolutely NOTHING to do with furthering existence. It also has a cause and effect relationship with a creature's adaptation to environments. An...

To clarify: Evolution- Changes in gene frequencies in a population over time. Adaptation- The ability for an individual to adjust to its surroundings such as enviornment. Plasticity- The range that an individual characteristic can develop in an organism (e.g. height can be different for an individua...

Squall's Girl....'nuff said.

I guess Inspecter Gadget might be the best cartoon for such talks...

It's my Dad's birthday today.

Today is my mother's birthday...

Out of the hand and into the keyhole.

It's Cap'n Crunch! He doesn't like the formality of "captain."

Not cereal killer?

Captain Planet smokes both of them.

Couldn't stand him. Give me Hemmingway any day.
