CONCLUSIONS:

By the first, a type of bacteria lover of carbon dioxide and heat, called Archaean anaerobic (or thermo acidophilus), merged with a swimming bacteria. Together, the two integrated components of the merger became the nucleocitoplasma, the base substance of the ancestors of the animal, plant and fungal cells. This protist early swimmer was, like their descendants today, an anaerobic organism. Poisoned by oxygen, he lived in sands and muds where abundant organic matter in rock crevices, in puddles and ponds where this element was absent or minimal.

After mitosis evolved in protists swimmers, other free-living organism was incorporated into the merger: a bacterium that breathed oxygen. They came even bigger, more complex cells. The triple complex oxygen respirator (lover of heat and acid, swimmer and oxygen respirator) became able to swallow food in the form of particles. These cells with nuclei, complex and amazing creatures swimming and breathing oxygen, first appeared on Earth perhaps as early as 2,000 million years ago. This second fusion, in which the anaerobic swimmer acquired oxygen respirator, led to cells with three components increasingly prepared to support dioxide levels Free Carbano that accumulated in the air. Together, the delicate swimmer, Archaean tolerant to heat and acid and oxygen respirator, now formed a unique and prolific individual who produced offspring clouds.

In the final acquisition of the generating series of complex cells, oxygen respirators swallowed, ingested, but could not digest photosynthetic bacteria bright green. Literal 'incorporation' came after a struggle in which undigested green bacteria survive and complete fusion prevailed. Eventually green bacteria became chloroplasts. The fourth member, these productive sunbathers were integrated with other previously independent partners. This final merger resulted in green algae swimmers. These ancient green algae swimmers are not only the ancestors of the current plant cells; All individual components are still alive and in good shape, swimming, fermenting, breathing oxygen.
