This could be anything, from earthquakes to migration to floods to disease, and so on, and so forth. In nature, population sizes naturally fluctuate even without such events, due to changes in the availability of resources, predation, and so on.

What must be true for hardy equilibrium to occur?

mating must happen randomly


What must occur for a population to grow?

For a population to grow, the birth rate must exceed the death rate, there must be enough resources available to support the increase in population, and factors that limit growth such as disease or predation must be controlled.


What are the four things that must happen for natural selection to occur?

For natural selection to occur, there must be genetic variation present in a population, some of which is heritable. This variation must lead to differences in survival and reproduction (differential fitness). Individuals with advantageous traits must pass those traits on to their offspring. Over time, these advantageous traits become more common in the population.


In order for evolution to occur in a population individuals with a trait that is naturally selected for must?

Individuals with the beneficial trait must survive and reproduce at a higher rate than those without the trait. This differential reproductive success leads to an increase in the frequency of the advantageous trait in the population over time, allowing for evolution to occur.


What condition is necessary for genetic drift to have a significant effect on a population A natural disaster must occur. The population needs to be small. Gene flow must occur. A portion of the p?

The condition necessary for genetic drift to have a significant effect on a population is when the population size is small. In smaller populations, genetic drift can lead to random changes in allele frequencies, impacting the overall genetic diversity of the population.
