Question

Place the following events in chronological order to show how speciation can occur.

1 Populations of the same species become geographically isolated from one another.
2 Populations experience adaptation, accumulating significant differences in their genetic material over time.
3 Populations are no longer able to successfully breed with one another.
4 Populations face different selective pressures in their unique environments.
write them in number like Ex: 2431

Answer 1

The correct answer would be 1423.

Speciation refers to the natural process by which the population evolved into different species.

It occurs due to several factors such as geographic isolation, reproductive isolation, genetic drift, mutation, et cetera.

In geographic isolation, the organisms of the same population are isolated into two different geographical areas.

• The different areas push different selective pressure on populations due to a different environment, resources, and biological interactions.
• Different populations accumulate different different adaptation, genetic variations et cetera.
• After several generations, the genetic variations become so severe that the two populations can not reproduce with each other.
• Thus, the new species have been formed.

Answer 2

The answer is;

1 Populations of the same species become geographically isolated from one another.
4 Populations face different selective pressures in their unique environments
2 Populations experience adaptation, accumulating significant differences in their genetic material over time.
3 Populations are no longer able to successfully breed with one another.
