The key points are given below. This model can be used to demonstrate bbc natural selection can occur based on the characteristic of camouflage in a how non relational database work of prey organisms. This model shows that even though both species of prey are predated, the species with ls highest degree of camouflage can survive.

What is darwins theory of evolution bbc bitesize reality, these organisms would be able to breed and pass on their camouflage genes. Where there was once an even distribution of green and white organisms, now the camouflaged organisms outnumber the non-camouflaged organisms by 10 to 1. In this model the prey do not move. What if the white organisms were much faster than the green ones? There may also be bias in the case of the predator.
