Chapter 55.2, Problem 2SB
Summary Introduction
To review:
The extinction rate today compared with the background extinction rate event in the fossil record.
Introduction:
Biodiversity is under a constant threat and there are various factors for extinction, such as habitat fragmentation, biological magnification of pollutants, and the threat of invasive species through competition, predation, and

What are some of the hypothesized causes of Earth’s biggest mass extinctions?
What are the five mass extinctions of the past and the current theory of the sixth mass extinction? For each extinctions, what caused the extinction and how was ecosystem stability impacted? Was there any speciation that occurred afterward?
If a sixth extinction event is occurring, how is it similar or different from the previous five mass extinctions? What sort of evidence do you think scientists look for to determine whether we are living through a mass extinction?
