Evolution is the idea that creatures who have unhelpful traits will die and creatures with helpful traits live and pass on that trait to the DNA of the next generation. Charles Darwin came up with it.
How Darwin Did It
Charles Darwin was studying finches when he noticed that they all had different beaks! So, he thought that they all evolved differently to get those different beaks.
The Bible And Evolution
Many Christians believe that evolution is not real and instead believe in Creation. There is much debate about this. The truth is still undecided.
