Chapter 17, Problem 4CT
Summary Introduction
To determine:
The ways in which the hypothesis saying that some human traits may have arisen by sexual selection can be tested.
Introduction:
Species of all the organisms have evolved themselves from time to time, according to their needs and changing natural environment around them. Different species adopt different modes of evolution. Natural selection is also one of the evolutionary modes that work on a population with a larger size. Sexual selection is one type of natural selection where individuals of a species prefer to mate with a partner of their desire who has certain special characteristics.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
