For those who believe in evolution. explanation please!

What is evolution? Um, yeah, that is a huge question. I'm not sure if you want a cookie-cutter definition, or a more personal one...
Evolution is, for the most part, defined as a process by which species adapt to their environments over time. Its about development, diversification and adaptation in order to survive and pass on genetic material.

Do I believe everything about it? LOLz. If I believed everything about it, I would believe a lot of contradictions. We don't know all there is to know about the world, so we don't know exactly how evolution works in all instances. Therefore, there are many contradicting theories within the umbrella theory of "evolution". I believe in the core of evolution, as I described in the first part of my answer. And I believe in that science not just because scientists tell me to, but because I can see evolutionary theory at work both historically and in modern times. It makes to me in terms of the world that I experience everyday. So the science coupled with my life experience leads to me to conclude that evolutionary theory, while flawed, is the best explanation that I have at hand for the existance of the universe, should I choose to even pretend I have enough knowledge about any of it to even think about such things.

I answer the clarified question you posed to caramelmilk, what makes evolution more believable to me is, as I said, my own life experience, seeing what I consider to be evolution in action. But as well as that, scientific evidence does play a part. Fossils for sure are good evidence, despite people denying fossils for reasons that escape me completely. Evidence is pretty clear that the development of fossils are dependent on so many factors, so the length of time it takes for a fossil to be made is highly variable. No one ever denied that. Never understood the whole 'fossils aren't real' argument... Anyway, there is other evidence relating to

I think it would be best if you read a book about it :) That can probably explain everything better than we ever could.
Evolution is quite complex, so if you really want to understand it, it takes more than a few sentences.
Basically it's about mutations, genetic drift and natural selection.

I'm no expert, but the basic concept of evolution is "survival of the fittest."

If you have two dogs, and one dog is really wimpy and doesn't fight for food while the other is strong and smart and takes all the food, the stronger one will survive to mate with girl dogs and pass one his genes. Therefore his children will likely be strong as well.

Super condensed and super basic...but like everyone else said, it's a vast topic and you should probably read a book or an article.

I do politely recommend Wikipedia's articles on evolution for a beginner, they're fairly well researched and anti-vandalism security quite high, most important, there's consistent effort to maintain neutrality. On the other hand there's "The Greatest Show on Earth" by Professor emeritus Richard Dawkins FRS FRSL, but that book isn't very neutral.

evolution by the dictionary is defined as: "any process of formation or growth; development"

basically it means that something(an animal, or cell, or a plant, ect.) changes over hundreds of years to change according to its environment.

As Darwin said "survival of the fittest". That is true. If there is more than one creature wanting a place to live, who ever is the most strongest, fittest, and best set to live there will survive.

if you want a better explanation I suggest Darwin, or just a science textbook.

I believe in all of it!!!

This is one definition of it:

"Evolution (also known as biological or organic evolution) is the change over time in one or more inherited traits found in populations of organisms.[1] Inherited traits are particular distinguishing characteristics, including anatomical, biochemical or behavioural characteristics, that are passed on from one generation to the next. Phenotypic expressions of these traits can be influenced by gene–environment interactions. Evolution may occur when there is variation of inherited traits within a population. The major sources of such variation are mutation, genetic recombination and gene flow. Evolution has led to the diversification of all living organisms, which are described by Charles Darwin as "endless forms most beautiful and most wonderful""


Why do I believe it? Well there's LOTS of proof of evolution, I mean, skeletons and such that have supported the theory have been dug up, and scientists have done LOTS of research on it.
I highly doubt that it would be taught in schools, or such a widely known, popularized, and researched theory if people weren't fairly certain of it.

I don't just believe things on faith, like you Christians do, I believe evolution because I've seen, heard of, and read about tons of proof of it.

And there's a REASON religion isn't taught in schools, but evolution IS, you know....
