Life of today has come into existence through?
Correct answer: B. Phyletic lineage
- A. Biodiversity
- B. Phyletic lineage
- C. Science
- D. Fossil
Explanation
The correct answer is 'phyletic lineage.' This term refers to the evolutionary history and development of a species or group of organisms. It explains how life has evolved from simple to more complex forms over time through a continuous sequence of ancestral and descendant species. The other options are incorrect because 'Biodiversity' relates to the variety of life forms, 'Science' is a method of acquiring knowledge, and 'Fossil' refers to remains of past organisms without explaining the process of evolution.
