The answer of that qeustion is natural selection of which animals produce offspring.
natural selection
If a population exists in an environment that changes very little, then natural selection may not provide any pressure to change. However, even under these conditions genetic driftoccurs, introducing random change within the parameters set by natural selection.
The environment is the '' natural selector. ''
natural selection
The growth or shrinkage of populations has nothing to do with natural selection, but with the availability of resources, and the ability of organisms to utilize those resources. This is also known as 'carrying capacity'. The natural tendency is for organisms to produce more offspring than the environment can support. So if the environment supports more individuals, then the population will automatically grow. If conditions change and the environment supports less individuals, then some individuals will starve or be otherwise unable to reproduce. Natural selection, in this case, "determines" which individuals pass, and which do not.

Natural Selection
According to natural selection the individuals can be rare from the enviroment
To the environment.
the theory of natural selection
Natural selection a theory by Charles Darwin
Natural Selection is a process which individuals are better adapted to their enviorment are more likely to survive and reproduce. Say there are turtles barely hatching and there are hungry seagul waiting to be fed, the fastest ones will make it to the water safely while the slow ones are being eaten. so eventually all the turtles in the sea will become faster to get away from predators. hopefully that answered your question.
