Explanation: These are key facts
y points:
Phylogenetic trees represent hypotheses about the evolutionary relationships among a group of organisms.
A phylogenetic tree may be built using morphological (body shape), biochemical, behavioral, or molecular features of species or other groups.
In building a tree, we organize species into nested groups based on shared derived traits (traits different from those of the group's ancestor).
The sequences of genes or proteins can be compared among species and used to build phylogenetic trees. Closely related species typically have few sequence differences, while less related species tend to have more.

N the brain<span>, dopamine functions as a </span>neurotransmitter<span>—a chemical released by </span>neurons<span> (nerve cells) to send signals to other nerve cells. The brain includes several distinct </span>dopamine pathways<span>, one of which plays a major role in </span>reward-motivated behavior<span>. Most types of rewards increase the level of dopamine in the brain, and many </span>addictive<span> drugs increase dopamine neuronal activity. Other brain dopamine pathways are involved in </span>motor control<span> and in controlling the release of various hormones. These pathways and </span>cell groups<span> form a dopamine system which is </span>neuromodulatory<span>.</span>
