Document Summary

With many functions, too much emphasis on one function causes others to suffer: the colony, a solution -- one day you (a single cell organism) are crawling around and run into another (an amoeba). You like to crawl around, it likes to ingest. So, the two of you team up, form cells or societies and make use of each other"s skills. You compensate for its shortcomings and it compensates for yours. Together, you are far more efficient, productive, and thus, more likely to survive and reproduce: specialization -- soon, specialization begins occurring (some movement, some sensitivity to environmental stimuli, others to irritation from environment, other secretion) This means a reduction in flexibility of individual cells. All of this leads to advancements in cell organization and development. Now, multi-celled organisms begin to evolve and adapt to their environments. Now we can take a closer look at the individual cells (neurons) and their components.
