Species Perfection?

Post by Mercury » Thu Jul 11, 2013 9:14 am

Hey guys. Natural Selection really intrigues me. I've actually always been interested in how certain species became the way they are now. And since Natural Selection only allows the best group of members of a species (well, roughly anyway) to survive in their habitat/environment, does that mean that over a very large period of time, in theory that species would become the most perfect on Earth? (If the conditions of every factor involved were to stay the consistent throughout those huge periods of time, that is - like where they live, the atmosphere and climate of that area, no new genes entering pool etc). And if this is possible, does that mean that if they reach the brink of their perfection, Natural Selection wouldn't apply to them since it doesn't have anything to sort out? Forgive me if my grammar is a little goofy. I'm in a hurry since I have exam tomorrow on this. :?

The problem is that the parameters aren't acheivable. There do seem to be species in stable niches that themselves have stabilized, but that's the closest you'll get.

As you know the process of natural selection in most cases takes an extremely long period of time depending on the organism and the environment it is adapting too, in other cases it may be a fairly quick process in evolutionary terms.

The way I see it is if the environment does not change then the evolutionary process stops as there is nothing to adapt to, if this is the case the organism reaches an evolutionary dead end you might say.

Take the Au crocodile for example, they have not changed much at all in the last 150 million years as they are already reached "perfection" in every way shape and form and rule their habitat there is nothing different to adapt to except changes in prey items and a few behavioral changes.

So I suppose you cant perfect the already perfect when it comes to evolution and natural selection, ya gotta admit they are pretty perfect as an ambush predator nothing really matches them.

Where it does chop an change is when you have populations of organisms evolving in an isolated area such as an island and the Galapagos group is a perfect example as Charles Darwin explains in one of his books Origin of Species, anyway probably not much help but I just had to have say as the whole process facinates me also :)

To the webmaster, not sure if there is an error in the page script or not but the page seems to be on a constant load? it is not spyware my end as it is clean on other sites it is if the page is hunting?

I suppose that depends on what you mean by perfection. Survival or reproductive success, survivability, becoming an apex predator, perfection is kind of nebulous concept when it comes to life.
