ABSTRACT

Bacteria Study and Changes along History



Irma Yaneth Castillo Basaldúa


Planet Earth since its formation thousands of millions of years ago, has been the scene of countless processes and changes in both the atmosphere, land and occupy the waters. Despite the extreme conditions that existed on Earth millions of years ago, single-celled life began to develop slowly in the seas following a slow but steady development, leading to the development of numerous microorganisms that have spread with relative ease along around the planet, such as bacteria, due to this largely available nutrients, and the ability of these microorganisms to adapt to the different environmental conditions. That adaptability is observable until today, can find descendants of these microorganisms grow in extreme environments such as high temperature water on the seabed and even outside our planet. The bacteria can be found not only in such extreme environments, we find in almost any habitat known to man, the most widely distributed organisms on the planet. Studies of bacteria have given rise to countless morphological findings and their role in the life of the planet and its possible evolution.
