On an evolutionary tree view available hint(s) on an evolutionary tree homologous characteristics form a nested pattern scientists are sure of the correct placement and relationships of all organisms organisms that are positioned close to each other are closely related the concept of descent with modification is not well-represented none of the listed responses is correct.

a. Homologous characteristics form a nested pattern

True

Homologous characteristics are used as a basis for building phylogenetic trees. They are similar characteristics among living beings because they were inherited from a common ancestor.

Explanation:

b. False

The evolutionary tree is ever-changing as new discoveries such as fossils and advances in genetic engineering research bring new lineages and new evolutionary relationships that can alter the tree.

c. False

Being close to each other in the tree does not necessarily mean that they are closely related

d. False

An evolutionary tree is built from the evolutionary history of species. Species are positioned in different branches that evolved from a common ancestor (branch point) through a series of modification events. At each branch point of the tree is the most recent common ancestor shared by all descendant species. When "new" features arise in organisms we can build their path of descent from their common ancestor.

hello there the answer is d
