Question

Which stage is the last stage of speciation? question 5 options: the populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring. The populations successfully interbreed. The populations become totally separated from one another. The populations are isolated and thus do not interbreed

Answer 1

D) The population become adapted to different environments and eventually becomes so different that they cannot interbreed to produce fertile offspring.

Step-by-step explanation:

Speciation is divided into three stages:

a) Separation.

b) Adaptation.

c) Reproductive Isolation.

Stage 1: Separation.

A part of the population separates and adapts to a new environment. Natural events such as tsunamis, tidal waves can cause organisms to separate from their initial habitat to a new environment.

Stage 2: Adaptation.

At this stage, the organisms evolve new traits that enable them to a new environment. They possess certain characteristics that enable them to fit into the new environment. Example The great white skin's color makes it difficult for it to be seen in the dark.

Stage 3: Reproductive Isolation.

At this stage, organisms of the same species reunite and do not interbreed. Here, species are isolated into new ones so they have the best adaptations for their new habitat.
