Which best describes the two types of shared characteristics?

1 - characteristics that remain in the common ancestor and the modern organism

2 - characteristics that are new and have been modified from what was found in the common ancestor

1 - characteristics that are new in the common ancestor and the modern organism

2 - characteristics that have been modified from what was found in the common ancestor

1 - characteristics that have been modified in the common ancestor but not in the modern organism

2 - characteristics that are new in both the common ancestor and the modern organism

1 - characteristics that remain in the common ancestor and the modern organism

2 - characteristics that are new in both the common ancestor and the modern organism

The first option which is:

1 - characteristics that remain in the common ancestor and the modern organism

2 - characteristics that are new and have been modified from what was found in the common ancestor

Explanation:

Shared characteristics are divided into 2 namely;

Shared Ancestral Characteristic

If a characteristic is found in all of the members of a group, it

is a shared ancestral character because there has been no

change in the trait during the descent of each of the members

of the clade. Although these traits appear interesting because

they unify the clade, in cladistics they are considered not

helpful when we are trying to determine the relationships of the

members of the clade because every member is the same.

And the Shared derived Characteristics

It is called a shared derived character because:

character derived from the ancestor is new and has been modified.
