Evolution

Front

What are mutations and why are they important in evolution?

Back

Mutations are changes in the DNA sequence of an organism. They are important because they introduce genetic variation, which is essential for a population to evolve.

Front

What trait did Magda most likely inherit?

Back

Magda most likely inherited her height, as it is a genetic trait.

Front

What is a vestigial structure?

Back

A vestigial structure is a body part that has lost its original function through evolution. It likely had a function in an early ancestor.

What process is responsible for the changes in horse size and strength over millions of years?

Back

Evolution by natural selection is responsible for the changes in horse size, strength, and speed.

Front

What does 'survival of the fittest' refer to?

Back

'Survival of the fittest' refers to natural selection, where individuals with favorable adaptations reproduce more successfully.

Front

Define evolution.

Back

Evolution is the process through which species change over time through genetic variation and 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.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals within a population, which is crucial for evolution.

Front

What is the significance of fossil records in understanding evolution?

Back

Fossil records provide evidence of how species have changed over time and can show the progression of evolutionary traits.

Front

What is adaptation in the context of evolution?

Back

Adaptation is a trait that enhances an organism's ability to survive and reproduce in its environment.
