Hows does evolution take place? I understand that its an accumulation of changes to adapt to an environment, but how does it change generation to generation? Is the set of traits that will be passed down to an offspring predetermined or does it change depending on how my environment is? Its seems too fascinating that my environment may change the set of dna that is passed down, or is that not the case?
In: Biology
They start as random mutations in the DNA. The process of copying DNA isn’t perfect, so occasionally mistakes make it in. A lot of these mutations are bad or don’t affect anything, but some them help you survive and make babies. If you get one of these mutations, you’re more likely to pass it down to your children, and they’ll pass it to their children and so on.
