Answer:The contrast of the difference between what is called "microevolution", and "macroevolution".
Microevolution concerns the transformation of traits in a population of a given species.
Macroevolution concerns evolution above the species level: it includes the diversification of high level taxa, (mass) extinctions, origin and diversification of clades, etc.
Speciation – the arising of new species, and the main processes likely to produce it stands at the boundary between those evolutions.
Notably, when people of the term "evolution" they typically think of macroevolution (think of Darwin's focus on species their origins and transformation).
Darwin's focused on species their origins and transformation.
Darwin on evolution proposed natural selection as the mechanism of evolution
- Note these important points he outlined:
• Individuals do not evolve: populations evolve
• Natural selection can amplify or diminish only heritable traits; acquired characteristics cannot be passed on to offspring
• Evolution is not goal directed and does not lead to perfection; favorable traits vary as environments change.
Explanation:
If a drug slows down central nervous system activity while increasing the activity of the main inhibitory neurotransmitter in the brain, then it is most likely to be a Depressant.
<h3>
How do neurotransmitters work and what are they?</h3>
Chemical messengers are called neurotransmitters to facilitate communication between nerve cells. Serotonin, dopamine, glutamate, and acetylcholine are a few of them. Numerous processes are controlled by neurotransmitters, including mood, sleep-wake cycles, and appetite.
<h3>
DEPRESSANTS</h3>
These medications, which are sometimes known as "downers," are available as liquid or colored pills and capsules. As they are intended to lessen the symptoms of mental illness, some medications in this class, including Zyprexa, Seroquel, and Haldol, are referred to as "major tranquilizers" or "antipsychotics." Xanax, Klonopin, Halcion, and Librium are examples of depressants that are frequently referred to as "benzos" (short for benzodiazepines).
