Threats to Biodiversity

27.8K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Genetic Drift

Natural selection—probably the most well-known evolutionary mechanism—increases the prevalence of traits that enhance survival and reproduction. However, evolution does not merely propagate favorable traits, nor does it always benefit populations.

The Evidence for Evolution

50.2K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Limits to Natural Selection

36.0K
Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.

The Fossil Record02:56

The Fossil Record

28.5K
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...

Area of Science:

  • Evolutionary Biology
  • Paleontology
  • Computational Biology

Background:

  • Extinction events are traditionally viewed as disruptive forces in evolution.
  • Their long-term impact on the evolutionary trajectory and adaptability of life remains a key area of investigation.

Purpose of the Study:

  • To test the hypothesis that extinction events can accelerate evolution by enhancing evolvability.
  • To investigate the indirect selection for rapid expansion into vacated ecological niches following mass extinctions.

Main Methods:

  • Utilized two computational models to simulate evolved behavior under extinction scenarios.
  • Analyzed the impact of simulated indiscriminate extinctions on the evolvability of lineages.

Main Results:

  • Simulated extinction events led to increased evolvability in computational models.
  • Demonstrated a computational link between extinction, niche vacating, and enhanced adaptive potential.

Conclusions:

  • Extinction events, despite short-term destruction, can foster long-term evolutionary acceleration.
  • Increased evolvability is a key outcome, enabling lineages to persist through multiple extinction events and promoting more prolific evolution.
