1. Describe two scientific theories relating to the evolution of the chemicals of life
A scientific theory is an explanation based on observations, reasoning and experimentations, especially one that has been tested and confirmed as a general principle helping to understand, explain and predict natural phenomena. A scientific theory must be based on careful and rational examinations of the facts. There are 5 major theories that account to the evolution and origins of chemicals of life. However two of these major theories are:
• Spontaneous Generation
• Biochemical Evolution or Chemosynthetic Theory
Spontaneous Generation Theory
Spontaneous Generation is an incorrect theory introduced by Aristotle, a Greek philosopher between 384 – 322 BC. Spontaneous Generation is a hypothetical process in which living organisms develop from non-living matter, suggesting life arose spontaneously i.e. Maggots from rotting meat. The theory further assumes that specific ‘particles’ of matter contained an ‘active agent’, which produced a living organism when conditions were suitable for this particular ‘active agent’.
Aristotle had influenced many to believe that …show more content…
The theory also implies that all life on earth evolved from a mutual cellular ancestor. There are a number of molecular similarities between all life forms, which indicate that all life evolved from one singular ancestor. The molecules of living organisms, which are rich in hydrogen-containing carbon, compounds, indicating there was no free oxygen on primitive earth, support this. Another proof is that DNA and RNA are the genetic bases of all life forms of earth and that ATP is energy used by all living organisms, suggesting a common origin of metabolism. These ‘proofs’ help support the Biological Evolution theory, making it a widely accepted scientific theory for the evolution and origins of the chemicals of
