Evolution and Natural Selection Concepts

The video tutorial explains evolution and natural selection, using rabbits as an example. It covers the diversity of life, genetic variation, and how species adapt to their environment. The concept of speciation is introduced, showing how populations can evolve into separate species. The video aims to help viewers understand the process of evolution and its impact on species over time.

What is the estimated percentage of species that have ever lived on Earth and are now extinct?

• 10%

• 1%

• 50%

• 99%

How long ago do scientists believe life first developed on Earth?

• 10 billion years ago

• 1 million years ago

• 3 billion years ago

• 500 million years ago

What is the process called where organisms better adapted to their environment tend to survive and produce more offspring?

• Mutation

• Genetic Drift

• Natural Selection

• Artificial Selection

In the rabbit example, which trait would likely increase in frequency if the environment became colder?

• Thicker fur

• Longer ears

• Shorter legs

• Brighter fur color

What advantage do rabbits with better eyesight or hearing have in a predator-prey scenario?

• They can camouflage better

• They can detect predators earlier

• They can dig deeper burrows

• They can run faster

What is the main factor that drives natural selection?

• Human intervention

• Genetic engineering

• Random chance

• Environmental pressures

What is the term for the formation of new and distinct species in the course of evolution?

• Natural Selection

• Adaptation

• Speciation

• Mutation

Why can't pygmy rabbits breed successfully with normal-sized rabbits?

• They live in different habitats

• They have different diets

• They have different mating seasons

• They are different species

Which of the following is NOT a result of natural selection?

• Extinction of less adapted species

• Adaptation to the environment

• Formation of new species

• Increased genetic variation

What is the primary cause of the change in inherited characteristics of a population over time?

• Natural Selection

• Migration

• Human Activity

• Climate Change
