Evolution
The change in heritable characteristics of biological populations over successive generations.
Also: Darwinian evolution
Definition
Evolution is the process of change in all forms of life across successive generations, driven primarily by natural selection, genetic mutation, genetic drift, and gene flow. Charles Darwin and Alfred Russel Wallace independently proposed the theory of evolution by natural selection in 1858. Over vast timescales, evolution accounts for the diversity of life and the common ancestry of all organisms on Earth.
Example
“The development of antibiotic resistance in bacteria is a rapid, observable example of evolution: bacteria with random mutations that confer resistance survive antibiotic treatment and pass that trait to offspring, eventually dominating the population.”
Usage Examples
- 1
“The team applied evolution best practices to improve their biology outcomes significantly.”
- 2
“Understanding evolution is essential for anyone building a career in STEM.”
When & How to Use
Use 'Evolution' when working in Biology contexts where evolution is the process of change in all forms of life across successive generations, driven primarily by natural selection, genetic mutation, genetic drift, and gene flow.
- ▸Applying evolution principles during a biology project or initiative
- ▸Explaining evolution to a junior team member or stakeholder unfamiliar with STEM
- ▸Evaluating options or proposals using evolution as a decision-making criterion
Etymology & Origin
The term 'Evolution' derives from professional usage and entered STEM professional usage as the field formalised in the 20th century.
History & Evolution
The concept of evolution has evolved alongside STEM. Early practitioners relied on informal methods; structured approaches emerged with the professionalisation of biology in the mid-20th century. Today, evolution is a standard part of STEM practice globally.
