Evidence of Evolution Through Natural Selection and the Contributions of Darwin and Wallace

Mr. Andersen discusses the evidence of evolution, focusing on Charles Darwin and Alfred Wallace's contributions. He explains natural selection, biogeography, fossil records, homology, and the role of DNA in evolution. The video highlights Darwin's observations and the compelling evidence supporting the theory of evolution.

Who is the lesser-known scientist who independently conceived the theory of evolution by natural selection alongside Charles Darwin?

• Thomas Huxley

• Jean-Baptiste Lamarck

• Alfred Wallace

• Gregor Mendel

What example did Darwin use to explain artificial selection?

• Pigeons

• Cats

• Horses

• Dogs

What is biogeography?

• The study of animal behavior

• The study of fossils

• The study of genetic mutations

• The study of the distribution of life forms over geographical areas

What did Darwin observe about the tortoises on the Galapagos Islands?

• They were all herbivores

• They could fly

• They had different shell shapes depending on their island

• They were all the same species

What was the main selective pressure for tortoises on Pinta Island?

• Temperature

• Vegetation height

• Predators

• Availability of water

Which animal's evolutionary history was used as an example of fossil evidence?

• Horse

• Elephant

• Dinosaur

• Whale

What is homology?

• The study of animal behavior

• The study of human evolution

• The similarity in characteristics due to shared ancestry

• The process of natural selection

What is considered the 'trump card' in evidence for evolution?

• Fossils

• Homology

• Biogeography

• DNA

How does DNA provide evidence for evolution?

• It determines the lifespan of organisms

• It records the history of mutations over generations

• It predicts future evolutionary changes

• It shows the physical traits of organisms

What analogy is used to explain the transmission of DNA mutations over generations?

• A game of telephone

• A treasure hunt
