BY9 Helpful Genes

Evolution is the changes within a species over a long time, like millions of years.

It could be like where there’s two adults and you have a kid and the genes in that child, they’re slightly altered a bit and give the baby of the two adult things, and if the baby … it turns out to help them, that kid will go on to pass on that genetic mutation so the rest of the species will change like that. If it’s not a helpful change, then the child wouldn’t be able to live on long enough to pass on the genes, but if it is helpful, then it will help it to survive where it lives and then it will pass on the genes to its kids and then it will carry on.
