Extinction rates have varied throughout history, with some periods experiencing increased rates due to factors like natural events and changes in climate. However, human activity in recent times has accelerated extinction rates significantly, leading to a current global crisis of biodiversity loss. Efforts are being made to combat this trend and protect endangered species.

How do biologists estimate extinction rates?
Biologists estimate extinction rates by monitoring population sizes, habitat loss, and factors affecting species survival such as climate change and human activities. They use mathematical models to predict future extinction probabilities based on current trends. Additionally, researchers collect data on species declines and the rate of biodiversity loss over time to assess and quantify extinction rates at a global scale.
What occurred when large numbers of species die out over a short period of time?
Mass Extinction

What caused the last mass extinction?
The Permian mass extinction occurred about 248 million years ago and was the greatest mass extinction ever recorded in earth history exterminating more than 95% of all life on EarthTwo theories have been proposed - the impact of a huge meteorite or comet over 10 kilometres in diameter, or a massive and prolonged volcanic eruption. The volcanic theory appears to be taking the lead at the present time.

What can scientists learn by studying fossils I. how the Earth's surface has changed over time II. the appearance of an organism and its structures III. how species have changed over time IV. how the?
By studying fossils, scientists can learn how species have changed over time (III), providing insights into evolution and extinction events. Fossils also reveal the appearance and structures of ancient organisms (II), which helps reconstruct past ecosystems. Additionally, they can indicate how the Earth's surface has changed over time (I), such as shifts in climate and geography, by showing where different organisms lived in relation to environmental conditions.
