Evolution & Natural Selection Flashcard

Front

What is the purpose of selective breeding?

Back

The purpose of selective breeding is to create animals with desirable traits.

Front

According to the principle of superposition, how do the ages of fossils in rock layers compare?

Back

Fossils found in the lower layer of rocks are older than those found in higher layers.

Front

Is artificial selection the same as survival of the fittest?

Back

False, artificial selection is not the same as survival of the fittest.

Front

What are the evidences for evolution?

Back

Fossil records, embryology, and similar body structures are all evidences for evolution.

Front

What happens to individuals in a population with advantageous variations?

Back

They are more likely to survive and reproduce.

Front

Define evolution.

Back

Evolution is the process by which different kinds of living organisms develop and diversify from earlier forms during the history of the earth.

Front

What is 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 fossil records in understanding evolution?

Back

Fossil records provide evidence of the historical changes in species and their development over time.

Front

What is the role of embryology in supporting the theory of evolution?

Back

Embryology shows that different species exhibit similar stages of development, indicating common ancestry.

Front

What does 'survival of the fittest' mean?

Back

'Survival of the fittest' refers to the idea that individuals best adapted to their environment are more likely to survive and reproduce.
