-Theory that eukaryotic cells evolved from symbiotic theory between 2 or more prokaryotic cells. Larger cell engulfed a smaller cell, engulfed cell (endosymbiont) became an internal part of engulfing cell (host cell). Mitochondria and chloroplast originated from bacteria.
+Theory that eukaryotic cells evolved from symbiotic theory between 2 or more prokaryotic cells. Larger cell engulfed a smaller cell, engulfed cell (endosymbiont) became an internal part of engulfing cell (host cell). MAC[^1] originated from bacteria.

 Ancestral prokaryote engulfed aerobic bacterium. Lived symbiotically.
 Other ancestral prokaryotes engulfed photosynthetic bacterium. Lived symbiotically.

 Evidence:
-* Mitochondria and chloroplast have a outer and inner membrane, theorized one from new, one from when it was independent.
-* M and C have their own DNA.
-* M and C can divide on their own independent of host cell.

+Species is a group in organism that interbreed in nature and produce fertile offspring. Gaps though, bacteria don't sexually reproduce, and there are separate species that are able to mate and create fertile children. 
+
+Three types of species.
+* Morphological Species:
+	* Studies shape, size, physics, structural features.
+	* Simple, quick.
+	* Most populations have variation.
+* Biological Species:
+	* Ability to reproduce in nature and produce fertile offspring.
+	* Most commonly accepted definition, objective.
+	* Can't test on asexually reproducing, extinct, and/or physically separated organisms.
+* Phylogenetic:
+	* Studies evolutionary history and relationships among organisms.
+	* Can be applied to extinct species.
+	* Not all evolutionary histories are known.
