infer the process by which early autotrophic prokaryotes produce oxyge What does the picture tell you about understanding evolutionary biology and understanding the concept of time in evolution? What were the first single-celled organisms, and where does the earliest evidence of their origin come from?

The History of Life on Earth; Phylogeny 2/17/22 ▯ Vocab: ▯ Phylogeny: the evolutionary history of a species/group of species ▯ Stromatolites: solid structure created by single-celled microbes called cyanobacteria (blue-green algae). The cyanobacteria form colonies and trap sediment with their sticky surface coatings. The trapped sediment reacts to calcium carbonate in the water to form limestone (fossilized record of early prokaryotes) ▯ Autotrophic prokaryotes: An organism capable of synthesizing its own food from inorganic substances, using light or chemical energy ▯ Serial endosymbiosis theory: the notion that complex living cel
