Evolution Practice part 2

Front

What is genetic drift?

Back

A change in the gene pool due to chance.

Front

Where do adaptations come from?

Back

Both mutations and genetic recombination are sources of adaptation.

Front

What is natural selection?

Back

The process where better adapted organisms survive to pass traits along to offspring.

Front

What is embryology?

Back

The study of embryos of various organisms to show a common ancestor because of similarities in development.

Front

What does variation refer to in biology?

Back

Genetic differences between organisms of the same species.

Front

What is the definition of evolution?

Back

The change in the heritable characteristics of biological populations over successive generations.

Front

What is a mutation?

Back

A change in the DNA sequence that can lead to new traits.

Front

What is the role of environmental factors in evolution?

Back

Environmental factors can influence which traits are advantageous, affecting natural selection.

Front

What is speciation?

Back

The process by which new species arise from existing species.

Front

What is the significance of fossils in understanding evolution?

Back

Fossils provide evidence of past life forms and show how species have changed over time.
