Question

Evolutionary history of an organism is known as-

• A. Phylogeny
• B. Ancestry
• C. Paleontology
• D. Ontogeny

Answer 1

The Correct Option is A

The question asks about the term that describes the evolutionary history of an organism. Let's analyze the options:

1. Phylogeny: This term refers to the evolutionary history and relationship of an organism or a group of organisms. Phylogeny is a key concept in biology used to construct phylogenetic trees, which depict the evolutionary pathways and relationships between different species over time.
2. Ancestry: This is a more general term, often used to describe an individual's familial lineage. It does not specifically address the evolutionary history in a biological context.
3. Paleontology: This is the scientific study of the history of life on Earth as reflected in the fossil record. While related, it focuses more on studying fossils rather than directly describing evolutionary histories.
4. Ontogeny: This term refers to the development and growth of an individual organism from a single cell to its mature form. It is not directly related to the evolutionary history of an organism.

After evaluating the options, Phylogeny is the most appropriate choice, as it specifically addresses the evolutionary aspect of how organisms have developed and are related to each other over time.

Therefore, the correct answer is Phylogeny.
