So how did you get to be a human? You weren't just magically made. Well if you're Christian then believe in God but for the people who believe in evolution, they'll understand how awesome evolution is. Evolution occurs when a species has a disadvantage and keeps dying. So that almost means evolution is a change in genes in a species to suit their needs. Evolution doesn't occur when a species doesn't need a change in a certain way. So if a giraffe needed to eat leaves, but the trees got taller, evolution would kick in and help the giraffes be able to eat the grass. Don't forget that evolution is a theory made by Charles Darwin that animals changed over time!
One of evolution's main purposes is to keep a species alive. Evolution doesn't just happen only when a species is dying or starving, it also changes the way males and females think of each other. There are three types of evolution: natural selection (where you have something because your nature told you that you needed it, example: hedgehogs having spikes to defend it self), sexual selection (what the opposite gender likes about you, example: female lions are attracted to a male lions' manes), and selective breeding (what a plant or animal got because of humans, example: plants have more vitamin and chickens cannot fly and have more meat). Those are the three main things that cause evolution. You may not notice it, but if you look through the past, you'll see that evolution has changed fishes, amphibians, cats, and even us! That's why evolution is so great and fun!

Oh and this is a clip of two giraffes fighting to get a mate. This is also evolution (sexual selection).
