What is evolution?

Evolution is the process through which living organisms undergo gradual changes over successive generations, resulting in the diversity of life forms ...

Who first articulated the theory of natural selection?

Charles Darwin first articulated the theory of natural selection.

What are homologous structures?

Homologous structures are anatomical features in different species that share a common origin but may have different functions.

Define genetic drift.

Genetic drift is the random change in allele frequencies in a population over time due to chance events, especially in small populations.

What is adaptive radiation?

Adaptive radiation occurs when a single species rapidly evolves into multiple species to exploit different ecological niches.

What is the significance of vestigial organs?

Vestigial organs are remnants of structures that were functional in ancestors but have lost most or all of their original function, providing evidence...

Explain convergent evolution.

Convergent evolution occurs when unrelated species evolve similar traits independently, often as a result of adapting to similar environments or ecolo...

What role does mutation play in evolution?

Mutation introduces new genetic variation, providing the raw material for evolution and contributing to adaptation.

How does biogeography provide evidence for evolution?

Biogeography studies the geographic distribution of species, showing how species evolved in response to geographic isolation and environmental pressur...

What is the Modern Synthesis of evolutionary biology?

The Modern Synthesis combines Darwin's theory of natural selection with modern genetics, forming a comprehensive framework for understanding evolution...
