Perform the following tasks:
describe the conditions on earth billions of years ago.
summarize theories of how life began on earth.
describe the relationship between organic compounds, nucleotides, rna, and a universal genetic code.
explain the connection between the beginning of life and the universal genetic code of almost all organisms.

The conditions on early Earth, some three to four billion years ago, are thought to be much different from what they are today. To begin with, the astronomical phenomenon called “the big bang” is defined by a theory proposing that the earth was one of the larger particles that coalesced after the initial universe explosion, or big bang, that spewed all the particles in the universe away from a central point and destined them to slowly revolve around that point.
