Evolution Quiz

The video tutorial covers key concepts in evolution, starting with fossils suggesting commonality among animals. It discusses Charles Lyell's proposal on Earth's age, Darwin's contributions to natural selection, and the collaborative work of Darwin and Wallace. The tutorial explains overproduction, competition, variation, and adaptation in organisms, and how natural selection determines survival and reproduction. Finally, it addresses the evolution of new species from a single species.

What do certain fossils suggest about animals?

• They are unrelated.

• They evolved independently.

• They are all identical.

• They have common ancestors.

Who proposed that Earth is much older than previously thought?

• Charles Lyell

• Alfred Wallace

• Charles Darwin

• Gregor Mendel

What is the main idea behind the theory developed by Darwin and Wallace?

• Inheritance of acquired traits

• Catastrophism

• Natural selection

• Spontaneous generation

What does the concept of overproduction in natural selection refer to?

• Producing more offspring than can survive

• Producing offspring with no variation

• Producing fewer offspring

• Producing identical offspring

What is the result of natural selection in terms of species evolution?

• Extinction of all species

• Reversion to ancestral species

• Evolution of one or more new species

• No change in species
