Evolution of Species

What causes the evolution of new species?

A. When there is no competition

B. When there are plenty of resources

C. When there is genetic variation

D. When there is isolation and genetic changes

Answer:

D

Explanation:

When there is isolation and genetic changes, new species can evolve. Isolation leads to separate gene pools and genetic changes can accumulate over time, resulting in the formation of distinct species.

The evolution of new species is a fascinating process that occurs over a long period of time. It involves various factors such as isolation, genetic variation, and natural selection. When a population of organisms becomes isolated from others of its kind, whether due to geographical barriers or other reasons, they can start to evolve separately.

Genetic changes within the isolated population, such as mutations and genetic drift, can accumulate over generations. These changes can lead to the development of new traits and characteristics that differentiate the isolated population from its original species. Eventually, if enough genetic changes accumulate, a new species may emerge.

Natural selection also plays a crucial role in the evolution of new species. It favors the survival and reproduction of individuals with traits that are better suited to their environment. Over time, these advantageous traits become more common in the population, driving the evolution of new species.

In conclusion, the evolution of new species is a complex process involving genetic changes, isolation, and natural selection. It demonstrates the incredible diversity and adaptability of life on Earth.
