After a mass extinction event many niches are left empty. New species eventually evolve and fill the niches where competition would otherwise have prevented such evolution.

Why mass extinctions occur and why they often mark divisions of geologic times?

Mass extinctions occur when extreme temperatures happen.https://science.howstuffworks.com/life/evolution/extinction3.htm


Characteristics of past mass extinctions?

Past mass extinctions are characterized by significant and rapid loss of biodiversity across various taxa, often resulting in the extinction of a large percentage of species within a relatively short geological timeframe. Common causes include dramatic environmental changes, such as volcanic eruptions, climate shifts, asteroid impacts, and ocean acidification. These events often disrupt ecosystems and food chains, leading to long-lasting impacts on the planet's biological diversity. Notably, the five major mass extinctions, including the Permian-Triassic and Cretaceous-Paleogene extinctions, have reshaped the course of evolution and the structure of life on Earth.


What are some of the causes of background and mass extinctions?

Background extinctions are typically caused by natural events such as climate change, volcanic eruptions, or asteroid impacts. Mass extinctions are often attributed to catastrophic events like major asteroid impacts, volcanic eruptions, or significant climate change, which cause widespread disruption to ecosystems and species. Human activities, such as habitat destruction, pollution, and overexploitation of resources, can also contribute to both background and mass extinctions.


How often does a Volcano affect the earth?

Volcanoes can errput unpredictably and cause radiations of heat over a very wide spectrum of land.


Is rapid diversification into new species that occupy novel niches?

Adaptive radiation is the rapid diversification of a common ancestor into a variety of different species that occupy different ecological niches. This process is often driven by the availability of new ecological opportunities.

What is spurts of rapid evolutionary change called?

Spurts of rapid evolutionary change are called adaptive radiations. This phenomenon occurs when a single ancestral species rapidly diversifies into a variety of forms that are adapted to different ecological niches. Adaptive radiations often occur in response to new environmental opportunities, leading to the rapid speciation and diversification of a lineage.

Is it true that extinctions only occur in the past?

Every single extinction has happened in the past. If an extinction is happening this instant we will not know about it until it is in the past. As and when any future extinctions happen we will not know about it until it is in the past.
