Question

How does cladistics help us understand phylogeny?

Answer 1

Answer: C.) Cladistics is based purely on the shared characters between organisms and their ranking in evolutionary history.

 

Explanation:

Phylogeny is the evolutionary science which derives a relationship among the ancient species with their descendants based upon common genetic, physiological and morphological characteristics. Cladistics represent the study of a group of organisms which exhibit a common ancestor. A clade includes organisms having a common ancestors and exhibit similar traits in them. A clade is sufficient to include the organisms in a phylogenic tree based upon their evolutionary history.

Answer 2

Answer:

The correct answer will be option-C

Explanation:

Cladistics is the approach used to classify the organism based on their shared characters on the basis of which the closely related organisms are grouped together.

The evolutionary biologist studies the physiological, genealogical, molecular and morphological characters on the basis of which the phylogenetic trees are constructed. In phylogenetic trees, the organisms are arranged according to their evolutionary history.

Thus, Option-C is the correct answer
