Extinction Training During the Reconsolidation Window Prevents Recovery of Fear
Published on: August 24, 2012
Summary
Charles Darwin viewed extinction as essential for evolution, a concept rarely discussed today. Our modern perception of extinction has shifted due to evolving scientific understanding and societal values.
Area of Science:
- Evolutionary Biology
- History of Science
Background:
- Charles Darwin's theory of evolution by natural selection.
- The historical context of 19th-century scientific thought.
Observation:
- Darwin considered extinction an ordinary and necessary component of evolutionary change.
- Contemporary views often regard extinction with dismay or horror, contrasting with Darwin's perspective.
- The essay investigates the linkage between Darwin's concept of "improvement" and natural selection.
Findings:
- The essay traces the reasons behind the changed valuation of extinction over time.
- It highlights how scientific information and ideological preferences have reshaped the concept of extinction.
- Darwin's own understanding of extinction evolved from "On the Origin of Species" to his later writings.
Implications:
- Challenges current assumptions about the role and perception of extinction in evolutionary processes.
- Encourages a re-evaluation of extinction within the broader framework of evolutionary theory.
- Provides insights into the dynamic interplay between scientific concepts and societal values.

Limits to Natural Selection
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.For one, natural selection can only act upon existing genetic variation. Hypothetically, redtusks may enhance elephant survival by deterring ivory-seeking poachers. However, if there are no gene variants—or alleles—for redtusks, natural selection cannot increase the prevalence of...
Evolutionary Psychology
Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the human psyche...
Conservation of Declining Populations
Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.
The Evidence for Evolution
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.The collection of fossils within sedimentary rocks give a record of common ancestry and often depicts the history of evolution.
Generalization, Discrimination, and Extinction
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

What is Natural Selection?
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.The Theory of Natural...
