I'll have a go.
Evolution is defined as
change in the genetic material of a population of organisms from one generation to the next.
First you have to acknowledge there are random genetic mutations, which i'm sure you do, otherwise how do you explain the existence of people with Down Syndrome? Genetic mutation, 47 chromosones instead of the regular 48.
Next you have to accept that there can be random genetic mutations which are benfeicial to the organism and can be passed amongst the population from generation to generation. For that see this link

In short there was a random genetic mutation which was of benfit to the organism which was then spread throughout the population from generation to generation. Natural selection at it's best.
What you have a problem with, and most ceationists do, is the concept of speciation. Speciation is the evolutionary process by which new organisms occur.
Gotta play some chess.
