Evolution occurs as a result of genetic variation like random mutations that happen in single-celled organisms.
Evolution occurs in gametes and during fertilization where genes are being made.
(Crossing over in meiosis)
- Independent assortment
- Movement of genes from one population to another
Evolution can also come from fossils that are remains of imprints of earlier organisms preserved in sedimentary
Older fossils are found deeper in the rock, while younger organisms are toward the top.
Fossils help see the evolution of what an early form of an organism used to looked like from what they are now
Hope that helps :)
