Question

Read the following questions and formulate an opinion using the concepts you've learned in this lesson.

1. Do you think evolution is still taking place in the Galapagos finches? Why or why not?
2. Discuss whether or not human activities lead to speciation. Explain your reasoning.

Answer 1

1. Yes, the evolution is still occurring as evolution never halts at any time period. Galapagos finches are famous for their diversity, which is witnessed by the way their beaks are formed and the functions they performed.

2. Yes, human activities can result in speciation. Speciation is illustrated as the procedure of evolution via which the population develops and turns into species. Human activities can result in speciation by influencing biodiversity at species, genetic, ecosystem, and community levels.

Answer 2

The main idea of evolution dictates that organisms will develop special traits to adapt to their environment and will ultimately pass these traits on to future generations; leading to a different organism than what existed in the past. The environment is constantly changing; it is dynamic. Once there is a change in the environment species will change to adapt so it is a fact that evolution is still taking place in the Galapagos finches because the environmental conditions does not remain the same indefinitely.
Speciation arises when one population gets split by some factor. Both groups can end up in regions with different envi
