• D. Fossil records showing transitional forms

Answer: (D)

Verified step by step guidance

1. Understand the concept of evolution: Evolution refers to the process by which species change over time through mechanisms like natural selection, genetic drift, and mutation. Evidence for evolution helps us understand how species are related and how they have changed over time.
2. Define direct evidence for evolution: Direct evidence refers to observable, physical, or tangible proof that supports the theory of evolution. Fossil records are a key example of this because they provide physical remains of organisms that lived in the past.
3. Explain fossil records: Fossil records are preserved remains or traces of organisms from earlier geological periods. They show the progression of life forms over time and often include transitional forms, which are species that exhibit traits of both ancestral and derived species.
4. Compare the options: Evaluate each option provided in the question. Similar dietary habits, the presence of chlorophyll, and migration patterns are not direct evidence of evolution because they do not provide physical proof of changes over time. Fossil records, however, directly show the progression and transitional forms of species.
5. Conclude why fossil records are the correct answer: Fossil records showing transitional forms are considered direct evidence for evolution because they provide concrete, physical proof of how species have evolved and adapted over time, supporting the theory of evolution.
