Evolution and Genetics

What is the theory of evolution?

• An idea that explains several phenomena at once

• A hunch about gene distribution

• A random guess about species diversity

• A hypothesis about natural selection

What is the main evidence for evolution provided by fossils?

• They prove that all species are unrelated

• They demonstrate the randomness of species diversity

• They reveal the changes in gene distribution over time

• They show that organisms from the past were similar to those today

What is the main reason for the high concentration of marsupials in Australia?

• They were isolated there due to continental drift

• They migrated there from other continents

• They were brought there by humans

What is the difference between microevolution and macroevolution?

• The time scale over which they occur

• The size of the organisms involved

• The type of genetic changes that occur

• The geographical location where they take place

What did the study of Darwin's finches on the Galapagos islands confirm?

• They evolved from a common ancestor and adapted to their environments

• They are not affected by geographical barriers

• They evolved from different species on the mainland

• They are not related to each other

What is the main idea behind the theory of evolution?

• Evolution is a debate that cannot be resolved

• Organisms adapt to their environment as it changes

• All species are unrelated and randomly created

• Life originated from multiple sources and evolved independently

What is the significance of the genetic similarity between different species?

• It demonstrates the randomness of genetic variation

• It proves that all species are identical

• It suggests that all species are related and share a common ancestor

• It indicates that species have evolved independently
