On an evolutionary tree .
A) None of the listed responses are correct.
B) the concept of descent with modification is not well-represented
C) homologous characteristics form a nested pattern
D) scientists are sure of the correct placement and relationships of all organisms
E) organisms that are positioned close to each other are closely related

The correct answer is: C) homologous characteristics form a nested pattern.

Explanation:

Evolutionary trees (also called phylogenetic trees) are diagrams used to represent the evolutionary relationship between different species based upon their characteristic and in order to show common ancestry between them.

The characteristics that are homologous to the species in the tree form the pattern of a nest, as they show the similarities between them.

C) homologous characteristics form a nested pattern

Explanation:

Homologous characteristics are similar characteristics shared by two different organisms because they were inherited from a common ancestor.

Evolutionary tree is basically a reconstruction of biological history which is based on similarities and differences among homologous attributeds (charactars) of the entities under scrutiny. These are basically the hypotheses about the relationships among different groups.

Homologies form nested patterns in evolutionary trees.Evolutionary trees can be made using different types of data , for example, anatomical and DNA sequence Data.
