Question

Describe the emergence of biological organisms in all their complexity from basic material origins to the world we see today. In your description, be careful not to use skyhooks and base your descriptions on evidence, not just proposition.This means that you should be highlighting how science has come to understand what you’re saying rather than relying solely on philosophy. Remember to be careful in your logic as we spoke about in class. It is not science to search for examples, but to search for evidence against. Single examples can be support but are not what we ‘search for’. Include at least the following elements in your description:

1.Emergence of functions that contributed to selection toward eukaryotes (make sure to explain the process not only components)

2. Emergence of functions that contributed to selection toward multicellularity.

3. Evolution of Sight

Explanation / Answer

Earth's atmosphere was violent and reducing in the beginning and it might have led to rise of simple organic compounds as shown my Stanley and miller experiment. (Murchison meteorite, a 4.5-billion year- old rock that landed in Australia in 1969, contains more than 80 amino acids, some in large amounts. These amino acids cannot be contaminants from Earth because they consist of an equal mix of d and l isomers thus hinting at a similar process on earth) These compounds must have polymerized to form proteins and nucleic acids which must have membraned into protocells(evidence shows vesicles are capable of duplication) developing into simple prokaryotes (fossil evidence of bacteria). Infolding of the membrane would have led to eukaryotism. This eukaryote must have engulfed an aerobic bacteria to develop mitochondria ( ribosomal evidence and fact the mitochondria has its own DNA) and then a photosynthetic bacteria to develop chloroplast ( chloroplasts have their own DNA). Multicellularity evolved with evolutionary advantage of specialization. Sight allowed procurement for food around 600 mya
