Habitat loss is the leading cause of extinction, as it destroys the homes and resources that species need to survive.

Amphibians are the most vulnerable group of organisms to extinction, due to their sensitivity to changes in their environment.

It is estimated that over 100 million species have gone extinct in the last 100 years, a rate of extinction that is unprecedented in the history of the planet.

Adaptation is the process by which species change over time in order to better survive in their environment.

Speciation is the process by which new species are formed, typically through the process of natural selection.

Extinction is the process by which species disappear from the planet, typically due to changes in their environment.

Extinction studies is the study of the causes, patterns, and consequences of extinction.

The Anthropocene is the current geological epoch, which is characterized by the significant impact of human activity on the planet.

The Human Impact Hypothesis is the idea that humans are responsible for the current mass extinction event.

The Natural Extinction Hypothesis is the idea that the current mass extinction event is a natural occurrence.

The Combined Extinction Hypothesis is the idea that the current mass extinction event is a combination of natural and human-caused factors.

The End of the World Hypothesis is the idea that the current mass extinction event is a sign of the end of the world.

The New Species Hypothesis is the idea that the current mass extinction event is an opportunity for new species to evolve.

The Wake-Up Call Hypothesis is the idea that the current mass extinction event is a wake-up call for humans to change their ways.
