Natural Selection. Definition: From among chance variations,
nature selects the traits that best enable an organism to survive and reproduce in a particular environment
. Example: According to natural selection, in a population of a certain organism, the one most suited to survive proliferates its genome.
What does natural selection have to do with psychology?
Evolutionary psychology is inspired by the work of Charles Darwin and applies his ideas of natural selection to the mind. Darwin’s theory
argues that all living species, including humans, arrived at their current biological form through a historical process involving random inheritable changes
.
What is an example of natural selection in psychology?
Examples of natural selection
When
exposed to antibiotics
, most bacteria die quickly, but some may have mutations that make them slightly less susceptible. If the exposure to antibiotics is short, these individuals will survive the treatment.
What is natural selection in psychology quizlet?
Natural Selection. process
by which individuals that are better suited to their environment survive and reproduce most successfully
; also called survival of the fittest. Variability (Requirements for natural selection) differences among organisms in terms of traits and genes.
What is natural selection example?
Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example,
treefrogs are sometimes eaten by snakes and birds
.
How do you explain natural selection?
Natural selection is the
process through which populations of living organisms adapt and change
. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

What are the 5 theories of evolution?
The five theories were:
(1) evolution as such, (2) common descent, (3) gradualism, (4) multiplication of species
, and (5) natural selection.
Is evolution an psychology?
Evolutionary psychology is
a theoretical approach to psychology that attempts to explain useful mental and psychological traits
—such as memory, perception, or language—as adaptations, i.e., as the functional products of natural selection.
What is the study of how natural selection influences behavior?
sociopolitical
, biological, psychosocial. Psychologists who study how natural selection influences behavior tendencies are working from the. evolutionary perspective.
Is natural selection random?
The genetic variation on which natural selection acts may occur randomly, but
natural selection itself is not random at all
. The survival and reproductive success of an individual is directly related to the ways its inherited traits function in the context of its local environment.
What does the theory of natural selection mean to you quizlet?
natural selection.
The process by which organisms best adapted to their environment survive & reproduce to pass on favorable traits to their offspring
. offspring.
What is the process of natural selection quizlet?
Natural selection is the
process by which random evolutionary changes are selected for by nature in a consistent, orderly, non-random way
. Selective pressure is any phenomena which alters the behavior and fitness of living organisms within a given environment.
What are disadvantages of natural selection?
- involves a lot of chance.
- environment of animal can become underemployed of resources in boom times, or over-employed in lean times.
- less control over breeding of animals at specific times can lead to overpopulated or underpopulated areas of a species.
How do diseases affect natural selection?
From an evolutionary perspective,
infectious diseases
have probably been the primary agent of natural selection over the past 5000 years, eliminating human hosts who were more susceptible to disease and sparing those who were more resistant.
What are the 4 components of natural selection?
There are four principles at work in evolution—
variation, inheritance, selection and time
. These are considered the components of the evolutionary mechanism of natural selection.
