Natural Selection

Front

What is Natural Selection?

Back

Natural Selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring. It is a key mechanism of evolution.

What is the HMS Beagle?

Back

The HMS Beagle was the ship that Charles Darwin traveled on during his voyage around the world, which contributed to his theory of evolution.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, indicating divergent evolution.

Front

What is variation in the context of evolution?

Back

Variation refers to the differences in traits among individuals of the same species, which can lead to natural selection.

Front

What is the significance of glycolysis in evolutionary biology?

Back

Glycolysis is a universal metabolic pathway that supports the theory that all life originated from prokaryotic cells.

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships among various biological species based on shared characteristics.

Front

What is divergent evolution?

Back

Divergent evolution is the process by which two or more related species become more dissimilar over time, often due to different environmental pressures.

Front

What is convergent evolution?

Back

Convergent evolution is the process where unrelated species develop similar traits due to similar environmental pressures.

Front

What is the role of DNA replication in evolution?

Back

DNA replication is a fundamental process that ensures genetic information is passed on to offspring, allowing for variation and evolution.

Front

What is extinction?

Back

Extinction is the end of an organism or a group of organisms, often due to environmental changes or loss of habitat.
