Question

Do all variations in a species have equal chances of surviving in the environment in which they find themselves? Explain.

Answer 1

No, all variations in a species do not have an equal chance of surviving in the environment in which they find themselves.

1. Variations refer to differences among individuals within a species, such as differences in size, colour, strength, or any other traits.
2. These variations arise due to genetic differences and mutations.
3. In a given environment, some variations may provide advantages for survival and reproduction. For example, a moth with colouration that blends into the environment will be less likely to be seen and eaten by predators.
4. Individuals with advantageous variations are more likely to survive, reproduce, and pass those traits to their offspring. This process is called natural selection.
5. Variations that are less suited to the environment have a lower chance of survival.
