What are Darwin's 5 key ideas?
1.Present-day species have evolved from ancestral species.
2.Organisms produce more offspring than the number which survive.
3.Offspring which are produced sexually show variation in their traits. Some are more suited to the prevailing environment.
4.Favorable traits allow an organism to survive longer and pass on those traits.
5.Over time, successive generations are modified. This gradually leads to the development of a new species.
