ecological exclusion
A genetic mutation within the population.
Changes in the frequency of a gene within a population can lead to genetic variation. This can impact the traits expressed in individuals and influence the population's overall genetic diversity. Over time, changes in gene frequency can result in evolution and adaptation within a population.
Education-now everyone knows what recycling is as a result
natural selection or genetic drift
Mutation can create new alleles, therfore can change allele frequencies in a population.
Populations can change through birth (increasing population), death (decreasing population), immigration (increasing population), and emigration (decreasing population). Changes in these factors can result in population growth or decline over time.
maybe its because many people went to battle and they died so that decreased the population of Europe.
No, organisms die.Evolution is the change in allele frequency over time in a population of organisms.
Genetic Drift
When you do positive work on an object, the object's energy increases and its motion or position may change as a result of your efforts.
competition between the organisms
