Adaptive radiation is demonstrated by Darwin's finches, where species evolved from a common ancestor to adapt to different ecological niches.

Adaptive radiation is not convergent evolution; it refers to the diversification of species from a common ancestor.

Hardy-Weinberg equilibrium describes the stability of allele frequencies in the absence of evolutionary forces.

Genetic drift has a greater impact on small populations, not large ones.

Transitional fossils provide evidence of the evolutionary link between fish and amphibians.

Panspermia suggests that life came from outer space, not from non-living organic molecules on Earth.
Ref: NCERT Class 12 Biology Chapter 6: Evolution Adaptive Radiation and Biological Evolution
The Hardy-Weinberg Principle states that allele frequencies remain constant in a population unless disturbed by evolutionary forces.

Mutations can be beneficial, harmful, or neutral depending on the environmental context and genetic impact.

The Founder Effect describes how a small isolated population can give rise to a new species due to genetic drift.
