Exploring Evidence of Evolution

What did Charles Darwin argue against, which was a common belief at his time?

• Species evolve based on need

• Species do not evolve

• Species evolve towards perfection

• Species evolve towards complexity

What does Darwin's theory of natural selection imply about species?

• They evolve to become perfect

• They evolve to adapt to their environment

• They do not change over time

• They become simpler over generations

Which of the following is NOT one of the four key pieces of evidence for evolution presented by Darwin?

• Genetic mutations

• Geographic distribution

• Homologous structures

• Fossil record

What does the geographic distribution of species suggest about evolution?

• Climate has no impact on evolution

• Similar environments lead to similar evolutionary traits

• Species do not migrate

• All species originate from the same location

What characteristic does the Archaeopteryx fossil display?

• Amphibian-like skin and scales

• Feathers and bony tail like dinosaurs

• Mammalian teeth and claws

• Feathers and beak like birds

What is the significance of the Tiktaalik fossil?

• It shows a transition from aquatic to terrestrial life

• It represents the first bird

• It is the oldest known fossil

• It disproves evolutionary theory

Which example illustrates the concept of vestigial structures?

• Human tailbone

• Insect wings

• Shark fins

• Bird feathers

Why are goosebumps considered a vestigial structure in humans?

• They have no function in modern humans

• They help in modern temperature regulation

• They are remnants of a primitive heating system

• They are remnants of a primitive cooling system

What modern discovery confirmed Darwin's theories?

• The classification of elements

• The invention of the microscope

• The discovery of DNA

• The structure of proteins

How has the discovery of DNA impacted our understanding of evolution?

• It has provided a mechanism for inheritance

• It has shown that evolution does not occur

• It has disproved all of Darwin's theories

• It has no relevance to evolutionary biology
