A period in Earth's history where many species disappear at the same time.

The formation of new and distinct species in the course of evolution.

A group of organisms capable of interbreeding and producing fertile offspring.

The process of bringing back extinct species using modern genetic techniques.

Genetic material from extinct hominins, like Neanderthals, that persists in the DNA of modern humans.

Various ways in which new species arise, like geographic isolation.

Rapid development and diversification of many new species.

Various factors, such as environmental shifts or catastrophes.

Large animals, especially mammals, that lived during a particular geological period.

The current geological epoch, marked by significant human impact on the Earth's ecosystems.

The ongoing mass extinction event, driven by human activities.

An extinct genus of giant horned turtles that lived on Pacific Islands and Australia.

An extinct giant lizard, also known as Megalania, that lived in Australia.

An extinct species of wolf that lived in North America during the Pleistocene.

An extinct species of mammoth that lived in the Pleistocene.

Human hunting, climate change, disease, and second-order predation contributed to the extinction of megafauna.

The rising levels of oxygen in the Earth's atmosphere, reaching a critical point, are believed to have played a crucial role in the emergence of larger, complex life forms.

A theory suggesting that Earth experienced periods of intense glaciation, with the entire surface covered in ice, before 650 million years ago. These extreme conditions could have altered the environment, potentially triggering evolutionary change.

HOX genes are master control genes that regulate the development of body segments in animals. Changes in these genes could have contributed to the emergence of new body plans and species.

The development of eyes, allowing for sight and visual hunting, triggered a cascade of evolutionary adaptations in animals. This led to a predator-prey arms race, driving diversification and complexity in the animal kingdom.

In a dynamic interplay, predators evolve to become more efficient hunters, while prey develop defenses and strategies to escape. This continuous back-and-forth drives rapid evolution in both groups.
