Learning Evolution

In this thread I learn evolution. Remember. For me and the reader in general, best to keep it brief; concise.

I'll start with a question. What exactly is evolution?

Edited To Add: All off topic posts will be deleted in this thread. Stick to the subject of Evolution.

Evolution is the biological process by which organisms adapt to their environments over multiple generations. If part of a species' population has an allele that makes it more likely to survive to reproduction, then it will reproduce at a higher rate than the population as a whole until the allele in question dominates completely. New alleles form through mutation, and the process repeats itself over and over again.

@BlueVeins Thank you for your response. I've addressed adaptation in my response to @basilfawlty89 below if you're interested. As to your response specifically: Quote from below is from: https://www.genome.gov/genetics-glossary/Allele

[quote]An allele is one of two or more versions of DNA sequence (a single base or a segment of bases) at a given genomic location. An individual inherits two alleles, one from each parent, for any given genomic location where such variation exists. If the two alleles are the same, the individual is homozygous for that allele.[/quote]

Allele: having two identical alleles of a particular gene or genes. "homozygous embryos" (Oxford)

[c=A69800]EDIT[/c]: I have to stop this and finish it (this post) tomorrow. In my research I'm having some difficulty with what exactly DNA is. I'll get back to this.
