Question

Write two differences between ontogeny and phylogeny.

Hint:

Ontogeny refers to the growth of an individual, while phylogeny is concerned with the broader evolutionary context of species.

Answer 1

Ontogeny and phylogeny refer to different aspects of biological development and evolutionary history. Step 1: Difference in definition.
- Ontogeny refers to the development of an organism from the fertilized egg to its mature form. - Phylogeny refers to the evolutionary history and relationships among species or groups of organisms.
Step 2: Difference in focus.
- Ontogeny focuses on individual development within a single organism. - Phylogeny focuses on the history and diversification of species over time.
Final Answer: 1. Ontogeny deals with the development of an individual organism, while phylogeny deals with the evolutionary history of species. 2. Ontogeny is specific to one organism, whereas phylogeny is concerned with the relationships between species.
