What does the wide variety of different types of animal eyes represent? what does the wide variety of different types of animal eyes represent?

The wide variety of the eye forms in the different types of the animals represents the intermediate forms of the evolution that most probably occurred in the common ancestors of the animals present today. The process natural selection and evolution ensures the survival of the different species. The evolution of the different eye forms must have occurred in the ancestors and have gotten selected over time.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
