Give an Example of Two Groups of Organisms That Share

Question

Examlex · Accepted Answer

The Answer is An example of two groups of organisms that share similarities due to shared ancestry is the similarities between humans and chimpanzees. Both humans and chimpanzees share a common ancestor, and as a result, they have many similarities in their genetic makeup, skeletal structure, and behavior. This shared ancestry has resulted in similarities such as the presence of opposable thumbs, similar facial expressions, and the ability to use tools.

On the other hand, an example of two groups of organisms that share similarities due to natural selection independently fashioning similar traits is the similarities between the Tasmanian wolf (Thylacinus cynocephalus) and the gray wolf (Canis lupus). Despite being from different continents and having different evolutionary histories, both the Tasmanian wolf and the gray wolf have evolved similar physical characteristics, such as a wolf-like body shape and carnivorous teeth, due to their similar ecological roles as top predators in their respective environments.

In the case of shared ancestry, the similarities between humans and chimpanzees are the result of common descent and the inheritance of traits from a shared ancestor. This is known as homology, where traits are similar due to shared ancestry.

In contrast, the similarities between the Tasmanian wolf and the gray wolf are the result of convergent evolution, where natural selection independently favors similar traits in different lineages due to similar environmental pressures. This is known as analogy, where traits are similar due to similar selective pressures rather than shared ancestry.
