Evolution - Pros and Cons.


No, this is not another "religion against science, and vice versa" thread. I'm tired of those. I want this thread to be only scientific info about evolution - so I'm going to posts articles about new discoveries connected about evolution when I can find them.

Here one to start with

Abundant ammonia aids life's origins
"...An important discovery has been made with respect to the possible inventory of molecules available to the early Earth. Scientists led by Sandra Pizzarello, a research professor at Arizona State University, found large amounts of ammonia in a primitive Antarctic asteroid. This high concentration of ammonia could account for a sustained source of reduced nitrogen essential to the chemistry of life..."

This is a portion of the asteroidal meteorite CR2 Grave Nunataks (GRA) 95229. A study published this week in the Proceedings of the National Academy of Sciences shows that researcher Sandra Pizzarello of Arizona State has discovered a high concentration of ammonia in this meteorite that could account for a sustained source of reduced nitrogen essential to the chemistry of life

Good idea, Anna. This'll be great for people doing projects on the topic. Here's an article for you dealing with cooperation among early humans.

I don't get it. What do you mean by cons of evolution? How do you determine that sort of a thing?

And while we are at it, what are the pros of evolution? This world is the only one we know, the species as we see them (or the older extinct ones that we know of), that's all there is/was. How do you look at that in terms of pros and cons? As opposed to what?

Agreed, Rosi. Maybe I'm slow or something....

But anyway: the cons of evolution? Humanity!

I chose this name because in this thread http://www.historum.com/religion/204...tml#post507000 certain forum-ites expressed the opinion that the theory of evolution is "unscientific", and whoever take it "don't think". I was always an advocate for mutual respect and discussing the both sides of any problem; so, I want to give here a place where everyone can post links to articles that deal with evolution and it's problems.

In my view:
1. "Pros" are the scientific researches, info and proofs that prove the validity and the viability of the theory.
2. "Cons" are any scientific researches, info and proofs that the theory is unvalid and unviable.

A mean scientific info, not religious or atheistic testimonies. For example, I don't want here the enddless repetitions of the type "I believe that I'm created, and whoever doesn't is a sinner", or "To be a creationist is dumb", and the useless verbal fights come out of such statements. I'm interested in articles that deal with real, provable, show-able problems and researches that support or disprove the Theory of Evolution, not only the evolution of humans, but evolution at all. So, I will put here dinos and all, origin of life, paleontology, prehistoric climate, etc.

Good one, Black Dog Fits right your signature, and my sentiments.
On a second though, I probably should have called the thread "Theory of Evolution - Pros and Cons", but I didn't think about that. This is my Bulgarian mind speaking, and it doesn't always make sense in English. And now I can't change the title, so....

I think the current title is better, Anna. After you just explained what you mean with "cons" of evolution, i think that definition would change again if you renamed the thread, no? What's a con of the theory of evolution?
