Extinction (GCSE Biology)

Which human activity is a major direct cause of modern extinctions by destroying or fragmenting habitats?

Which evidence from the fossil record supports the idea of evolution by natural selection?

A sudden large reduction in the size of a population due to an environmental event can reduce genetic variation. What is this event called in evolutionary terms?

Which practice by humans is an example of artificial selection that can reduce genetic diversity and potentially increase extinction risk for a domesticated breed?

Which type of speciation occurs when geographic isolation (e.g., a mountain range or river) separates populations leading to reproductive isolation?

What is adaptive radiation and how can it relate to extinction events?

Which term describes the complete disappearance of all members of a species from Earth?

Why is genetic variation within a species important for preventing extinction?

Which genetic mechanism can reduce the adaptive potential of a population and increase its extinction risk after inbreeding?

How does reduced population size due to human hunting or collection make extinction more likely?

What role do mutations play in evolution and extinction?
