If there is no reason to change (constant climate), then change won't occur. For example, a desert is basically always dry and hot with sand and few clouds. If a creature is fit for the climate, it will continue to exist until a severe enough climate change. For a real world example, in pre-industrial Europe, the birch trees were white. This permitted white moths to survive and not get eaten by the owls that hunt them, until the industrial revolution. Ash got on the birch trees, changing the color of the trees to a darker black. The white moths stood out, and therefore got eaten, permitting the black variant of the moths to thrive, where they were close to complete eradication before the revolution.
Answer:
Antipsychotic drugs have been developed to target both the positive symptoms AND the negative symptoms of schizophrenia by targeting both dopamine and serotonin receptors in the brain.
Explanation:
Schizophrenia is a disorder that affects the ability of a person to feel things, think and behave accordingly. There are several symptoms of schizophrenia like hallucinations, social isolation, responding inappropriately to surroundings and stimulus, being emotionally vulnerable, in severe cases an individual may try to harm themselves and become extremely aggressive. Dopamine and serotonin both play vital roles in schizophrenia. It was detected that dopamine levels were low in patients suffering from schizophrenia. Thus, antipsychotic drugs were developed which affected the receptors of dopamine and serotonin, sequentially reducing symptoms and effects of schizophrenia.

A high level of gene flow into a population increases genetic diversity in a population. A high level of gene flow out of a population decreases genetic diversity in a population. Genetic drift is the change in allele frequencies due to "sampling error" factors. Typically, genetic drift has the biggest impact on small populations.
Gene flow (or gene migration) is a mechanism of evolution (change the allele frequencies) which transfers genetic variation among populations due to migration. High level of gene flow decreases the genetic differentiation between the two populations.
Genetic drift is a mechanism of evolution that acts by chance (“sampling error”) often when a population is reduced in size by a natural disaster (bottleneck effect) or when a small group leaves the main population and forms a colony (founder effect).
