Well since many camels have had the bad design of having rough and skinny legs they begin to die out slowly and many other camels with good cell and physical mutaion like having good, Strong legs and smooth hoofs they live and carrie on their mutaion.
How does natural selection lead to adaption in population ?
For instance this helps the organism because Since the floor is hot it is very difficult for a animal to walk over it especially when walking for miles these hoofs help them walk long distances without having pain and without there feet burning.
The first camels have strong feet they also have rough feet which doesn't help them move around
The struggle for existance where the camel skinny and rough feet that did not let them walk around
Camels couldn't of existed if this mutation would have not accrued the wide foot lt the camels feet no burn from the hot sand
The gene pool in camels would change because of that one mutation and now there is no camels with the bad mutation design of the skinny legs and rough feet although there may be on or two the gene is rarely carried now
