- Slide: 9
- This is becuase a long time ago the very first plant herbavours where born with a mutation that shifted thier eyes more to the side of thier heads and that helped them be able to see predetors coming from the sides and so they could survive longer and eventually be able t pass on that mutation to thier children.
- This doesnt mean that mutations are inherantly bad however as mutations led to the evolution of every animal and person to ever live.
- Slide: 10
- To recap: mutations are errors that happen when DNA gets copyed, prey animals mutated to have eyes on the side of thier head while predators mutated to have eyes on the front of thier head, some mutations arent helpfull or harmful and others arent notacable but most are harmful, but mutations led every animal and human alive.
