Answer:
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.
The study of a living being is called biology.
The correct answer is 1 and 2.
1- characteristics that remain in the common ancestor and the modern organism.
