What are adaptations?

Back

Adaptations are traits that enhance an organism's ability to survive and reproduce in its environment.

Front

Where do adaptations come from?

Back

Adaptations come from mutations and genetic recombination.

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 role do mutations play in evolution?

Back

Mutations introduce genetic variation, which is essential for a population to evolve.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals within a population.

Front

What is embryological development?

Back

Embryological development is the process by which embryos develop, providing evidence for evolutionary relationships among species.

Front

What is the significance of vertebrate embryos?

Back

All vertebrate embryos pass through similar stages of development, indicating a common ancestry.

Front

What are variations in a species?

Back

Variations are the differences among individuals in a species, such as different beak shapes in birds.

Front

What is selective breeding?

Back

Selective breeding is the process of breeding plants and animals for specific traits.

Front

What is the difference between genotype and phenotype?

Back

Genotype is the genetic makeup of an organism, while phenotype is the observable characteristics.
