Evidence of evolution from the field of paleontology examines which of the following?

• A. Fossil records that show changes in species over time
• B. Genetic similarities between living organisms
• C. Biogeographical distribution of species
• D. Comparative embryology of different species

Answer: (A)

Verified step by step guidance

1. Understand the field of paleontology: Paleontology is the study of fossils, which are the preserved remains or traces of organisms from the past. It provides direct evidence of organisms that lived in different geological periods.
2. Focus on the evidence paleontology provides: Fossil records are the primary data source in paleontology. These records show the physical structures of ancient organisms and how they have changed over time, offering insights into evolutionary processes.
3. Eliminate unrelated options: Genetic similarities, biogeographical distribution, and comparative embryology are important evidence for evolution, but they are not directly studied in paleontology. These fields fall under molecular biology, biogeography, and developmental biology, respectively.
4. Relate fossil records to evolutionary change: Fossil records allow scientists to trace the gradual changes in species over millions of years, showing transitional forms and common ancestors, which are key to understanding evolution.
5. Conclude that the correct answer is 'Fossil records that show changes in species over time,' as this directly aligns with the focus of paleontology in studying evidence of evolution.
