Answer
Fossils and living organisms both provide evidence for the process of evolutionary change by documenting the historical and current biodiversity on Earth.
Solution
a
Fossils: Fossils are the preserved remains or traces of organisms from the past. They form a chronological record of past life and can show a progression of form in different species over time
b
Living Organisms: Current biodiversity among living organisms can be studied genetically and morphologically to infer evolutionary relationships. Comparative anatomy and DNA analysis can reveal common ancestors and the mechanisms of evolution
Key Concept
Evolutionary Record
Explanation
Fossils provide a direct record of past life forms and their changes over time, while living organisms allow scientists to reconstruct evolutionary relationships and understand the mechanisms of evolution.
