Unit 10: Evolution Test Review

Front

What is the term used to describe the human-guided process of manipulating the genetic makeup of species to produce desired traits?

Back

Selective breeding.

Front

What do homologous structures in different species suggest about their evolutionary relationship?

Back

These species likely evolved from a common ancestor.

Front

What scientific evidence supports evolutionary changes?

Back

The fossil record of ancient life forms.

Front

What can be inferred about the evolutionary relationship between birds and dinosaurs based on Archaeopteryx?

Back

Birds may have evolved from dinosaur ancestors, as indicated by shared physical traits.

Front

Which principle of biology explains the survival and reproduction of organisms best adapted to their environment?

Back

Natural Selection.

Front

Define evolution in biological terms.

Back

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

Front

What is genetic drift?

Back

Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles in a population.

Front

Explain the concept of natural selection.

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is the significance of the fossil record in understanding evolution?

Back

The fossil record provides evidence of the history of life on Earth and shows how species have changed over time.

Front

What are vestigial structures?

Back

Vestigial structures are body parts that have lost their original function through evolution.
