Question

What is evolution? Write two evidences of evolution.

Hint:

Recall the fossil record and homologous-organ evidence as classic proofs of evolution.

Answer 1

Step 1: Definition:
Evolution is the gradual, heritable change in the characteristics of a population of organisms over successive generations, through which new species arise from pre-existing ones (descent with modification).

Step 2: Evidence 1 — Fossil Record:
The fossil record, when arranged by geological age, shows a progressive sequence from simpler to more complex organisms and displays transitional forms (e.g., the fossil sequence in horse evolution), directly documenting change over time.
