Answer:

Founder effect

Explanation:

In founder effect , a small population get separated from the larger ancestral population which undergo strong genetic drift in order to diverge the founder population from the ancestral population through combination of allele or rare alleles at a very high frequency.

There is a lack of genetic diversity and hence the genetic variation as the mating population size is small.

Two of the main systems that control almost every action in our body are our nervous system and endocrine system which have to have inner communications and communication with our brain.

As stated in the question, nervous system uses neurotransmitters for communication which are chemicals released by neurons to generate electrical signals that make the communication possible.

The main mean of communication that our endocrine system uses is substances that are called "Hormones" which are produced by certain glands and organs in our body and are usually released into our bloodstream to effect the functions of other organs and our body. Hormones can be used for both communication of the endocrine system itself and for the communication of other organs and our brain.
