The forearm of birds, reptiles, and humans illustrates a homologous body structure.
- Similar physical characteristics found in species with a shared origin are known as homologous structures, although these characteristics have entirely different biological purposes.
- The limbs of humans, cats, whales, and bats are examples of homologous structures.
- All of these structures—arm, leg, flipper, and wing—are supported by the same type of bone structure.
- The arms of a person and the wings of a bat are excellent examples of homologous structures. Because both bats and people are mammals, they have a common ancestor.
- Even though they appear considerably different from one another from the outside, a bat's wing and a human arm have remarkably comparable internal bone structures.
- Wings help bats fly, whereas arms enable human interaction with their environment. The wing and the arm also have various purposes.

Answer:
the diagram shows the body structures that are similar though in different species due to common ancestry, this evidence is comparative anatomy.
This shows that recessive alleles are not always eliminated by natural selection.
<h3>Natural selection: what is it?</h3>
- One method of evolution is natural selection.
- More environment-adapted organisms are more likely to survive and pass on the genes that contributed to their success. Over time, species change and diverge as a result of this process.
- Natural selection, which occurs over time as heritable features that aid organisms in surviving and reproducing grow more prevalent in a population, was another process Darwin proposed for evolution.
<h3>What variables influence natural selection?</h3>
Reproduction, heredity, variation in organism fitness, and diversity in individual traits among population members are the four prerequisites for natural selection to take place.
