Question

A taxon such as the class Reptilia, which does not include its relatives, the birds is..... A. really an order. B. a clade. C. monophyletic. D. polyphyletic. E. paraphyletic.

Answer 1

Answer:

c . monophyletic

Explanation:

In taxonomy, a group is paraphyletic if it consists of the group's last common ancestor and all descendants of that ancestor excluding a few—typically only one or two—monophyletic subgroups. The group is said to be paraphyletic with respect to the excluded subgroups. The arrangement of the members of a paraphyletic group is called a paraphyly. The term is commonly used in phylogenetics (a subfield of biology) and in linguistics.

Answer 2

=> A taxon such as the class Reptilia, which does not include its relatives, the birds is paraphyletic.

=> This is a paraphyletic group because it excludes the mammals (“Mammalia”) and the birds (“Aves”). Both of these groups are descendants of the first animals with amniotic development, the “Amniota”.
