Explain the Concept of Monophyly as It Applies to the Animals.How

Question

Examlex · Accepted Answer

The Answer is Monophyly refers to a group of organisms that includes a common ancestor and all of its descendants. In the context of animals, monophyly refers to a group that includes all animals that share a common ancestor and excludes any other organisms. This concept is important in understanding the evolutionary relationships and classification of animals.

The relationships of placozoans and poriferans contribute to our understanding of the base of the animal tree shown on the inside cover of the book because they help to determine the earliest branching events in animal evolution. Placozoans and poriferans are considered to be some of the simplest and most primitive animals, and their placement in the animal tree can provide insights into the early diversification of animal life.

By studying the relationships of placozoans and poriferans, scientists can gain a better understanding of the common ancestor of all animals and the evolutionary processes that led to the diversity of animal life we see today. This information can help to refine and improve the accuracy of the animal tree and our understanding of the evolutionary history of animals. Overall, the relationships of placozoans and poriferans contribute to our understanding of the base of the animal tree by providing important insights into the early stages of animal evolution.
