However, in some organisms terrestrial evolution allows the loss of exoskeleton and formed a more mobile endoskeleton,
The four reasons are
1) There is an over population.
2) There is a genetic variation in certain offspring that is helpful to survival.
3) The species struggle for survival.
4) The ones that lives will reproduce and pass on their genetic variation.
