16 Questions
What did paleontologists collect as evidence to show a slow process of change in organisms that inhabited the Earth in the past?
Fossils
What do scientists suspect gave rise to all species as early as the 1900s?
Some kind of change
How did organisms evolve through time?
By changing their morphological appearances due to environmental factors, interactions, and adaptations
What is the basis of the present system of classification of organisms?
Evolutionary relationships
What was believed to have happened to modern organisms according to the evidence collected by paleontologists?
Descended from early organisms through evolution
Why did animals and plants change their morphological appearances according to the text?
Due to their environment, interactions, and adaptations made to survive
What did Charles Darwin articulate as the tenets of the Theory of Evolution?
Descent with modification from a common ancestor and natural selection as the mechanism for descent with modification
What provides evidence of when organisms lived on Earth, how species have evolved, and how some species have gone extinct?
Fossil record
What do fossils mainly consist of?
Mineralized or hardened traces of dead organisms
What do transitional species in the fossil record demonstrate?
Evolutionary change from ancestral organisms to present-day ones
What does the comparison of how organisms are put together provide evidence for?
Evolution
What is the role of genetic drift in evolution?
Creating new variations within a population
What does the concept of descent with modification refer to?
Changes in species over generations due to heritable variations
What is the main mechanism for descent with modification according to Charles Darwin's theory?
Natural selection acting on heritable traits
How do fossils provide evidence for evolution?
Documenting the patterns of evolution from ancestral to present-day organisms
What is the purpose of comparative anatomy in understanding evolution?
Providing important evidence for evolutionary relationships among different species
Test your knowledge on the process of evolution, focusing on the evidence for evolution, the origin and extinction of species, and the classification of organisms. This quiz will assess your understanding of natural selection, descent with modification, and the present system of classification of organisms.
