An Evolution-Related Event is an event represented by an Evolutionary theory.
- Context:
- It can (typically) involve significant changes in a population due to natural selection, genetic drift, or other evolutionary mechanisms.
- It can (often) be documented through fossil records or observed in living organisms.
- It can include phenomena such as speciation, where new species arise from existing ones.
- It can involve adaptation events where species develop new traits to survive in changing environments.
- It can cover extinction events that significantly alter the course of evolution by removing certain species.
- It can be studied across various timescales, from rapid changes over a few generations to gradual changes over millions of years.
- It can provide insight into evolutionary processes and help in understanding the history of life on Earth.

- Example(s):
- a Host Switching Event that demonstrates how parasites adapt to new hosts, leading to new evolutionary paths.
- an Egg-Sperm Evolutionary Event that highlights the evolutionary changes in reproductive strategies and mechanisms.
- a Mass Extinction Event like the one that led to the demise of the dinosaurs, paving the way for the rise of mammals.
- a Speciation Event where a population splits into two distinct species due to geographical isolation.
- an Adaptive Radiation Event where a single species rapidly evolves into multiple new species to fill various ecological niches.
- a Bottleneck Event where a population's genetic diversity is drastically reduced due to a significant drop in numbers.
- a Founder Effect Event where a new population is established by a small number of individuals, leading to reduced genetic variation.
- an Artificial Selection Event where humans selectively breed plants or animals for desired traits.
- a Sympatric Speciation Event where new species evolve from a single ancestral species while inhabiting the same geographic region.
- a Coevolution Event where two or more species influence each other's evolutionary paths through close ecological interactions.
- a Darwin's Finches Event where the beak shapes of finches evolved on the Galápagos Islands to exploit different food sources.
- a Peppered Moth Evolution Event where the coloration of peppered moths shifted due to industrial pollution and natural selection.
- a Horizontal Gene Transfer Event where genetic material is transferred between different species, enhancing genetic diversity.
- a Gene Duplication Event where duplications in the genome lead to new genetic material that can evolve new functions.
- a Complex Molecule Creation Event where simple organic compounds undergo chemical reactions leading to more complex molecules, essential for the origin of life.
- a Miller-Urey Experiment where simulated early Earth conditions produced organic compounds from inorganic precursors.

- Counter-Example(s):
- a Random Catastrophic Event that impacts life but is not driven by evolutionary mechanisms, such as a volcanic eruption.
- a Cultural Evolution Event which pertains to changes in human societies and cultures rather than biological evolution.
