Evolution

What is Variation in the context of evolution?

Back

Variation refers to the genetic differences among individuals within the same species, which can lead to different traits.

Front

Why are advantageous traits more likely to be passed onto offspring?

Back

Advantageous traits are more likely to be passed onto offspring because individuals with these traits are more likely to survive and reproduce.

Front

What are mutations?

Back

Mutations are changes in the DNA sequence that can be helpful, harmful, or neutral, leading to new traits in organisms.

Front

What does the fossil record tell us about the age of fossils?

Back

The fossil record shows that fossils found in deeper rock layers are generally older than those found in higher layers.

Front

What is a Mutation?

Back

A mutation is an error in DNA copying that results in a new trait, which can affect an organism's survival.

Front

Define 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 Adaptation?

Back

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

Front

Explain the concept of Selective Breeding.

Back

Selective breeding is the process of breeding plants and animals for specific traits, often used in agriculture.

Front

What is the significance of genetic variation in a population?

Back

Genetic variation is crucial for a population's ability to adapt to changing environments and survive.

Front

What is the role of the environment in evolution?

Back

The environment influences which traits are advantageous, shaping the process of natural selection.
