Change Over Time (Evolution)

What is evolution?

• Evolution is the process through which species change over time through variations and natural selection.

• Evolution is the study of ancient fossils and their habitats.

• Evolution is the belief that species were created in their current form and do not change.

• Evolution is a method of improving agricultural crops through selective breeding.

What is the significance of adaptations?

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

• Adaptations are changes that occur in an organism's physical appearance only.

• Adaptations are behaviors that organisms learn from their parents.

• Adaptations are temporary changes that do not affect reproduction.

Why are variations important for evolution?

• They are necessary for the survival of all species.

• Variations can lead to the development of new species over time.

• Variations have no impact on evolution.

• They help in maintaining the genetic diversity of a population.

What is the fossil record?

• A historical sequence of life on Earth, as documented by fossils.

• A collection of ancient artifacts from human civilizations.

• A geological layer that contains only dinosaur bones.

• A record of all the species that have ever existed on Earth.

What is natural selection?

• Natural selection is the process where organisms with traits better suited to their environment are more likely to survive and reproduce.

• Natural selection is the method by which humans breed plants and animals for specific traits.

• Natural selection is the phenomenon where all organisms have an equal chance of survival regardless of their traits.

• Natural selection is the process of creating new species through genetic engineering.

What is a fossil?

• A type of rock formed from volcanic activity.

• The preserved remains or traces of an organism that lived in the past.

• A living organism that has not yet been discovered.

• A mineral that is found in sedimentary layers.

How does environmental change affect evolution?

• Environmental changes have no impact on evolution.

• Environmental changes can create new challenges and opportunities, influencing which traits are favorable.

• Environmental changes only affect the physical characteristics of organisms.

• Environmental changes lead to immediate extinction of species.

What does 'common ancestor' mean?

• A species that has no relation to any other species.

• A species from which two or more different species have evolved.

• A species that is the most recent in a lineage.

• A species that is extinct and has no descendants.

What is the role of competition in evolution?

• Competition leads to extinction of all but the strongest species.

• Competition can drive natural selection, as organisms compete for limited resources.

• Competition has no significant impact on evolution.

• Competition encourages genetic diversity among species.

What is extinction?

• Extinction is the end of an organism or a species, often due to environmental changes or competition.

• Extinction is the process of an organism adapting to its environment over time.

• Extinction refers to the increase in population of a species.

• Extinction is the migration of species to new habitats.
