Question
Changes caused by the environment in the phenotype are not significant in the process of evolution of new species because:
- The environment keeps changing
- They cannot be inherited
- They can be inherited
- They are genetic changes
Hint:
They are not genotypic changes.
The correct answer is: They cannot be inherited
Environmental factors such as diet, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens can all impact which of an animal's genes are expressed, which ultimately affects the animal's phenotype.
