Humans have only inhabited the earth for a fraction of the time that life has existed. Chemical evolution has produced a primitive self-maintaining chemical system with metabolism capabilities for a primitive cell called a "protocell". The experiment consisted of two types of RNA, termed long and short RNA. Outline the experiments of Miller and Urey into the origin of organic compounds. The driving force behind this theory is that through chemical selection, RNA with special properties was passed on through many generations. Download Natural Selection Worksheets Answer Key PDF 4.

Darwin spent over 20 years traveling around the world and making observations before he fully developed his tural Selection can cause either an increase or a decrease in... Aristotle was the first scientist to articulate a theory of evolutionary change. RNA molecules that replicated imperfectly would produce daughter molecules with slightly different sequences. Although scientists cannot directly address how life on Earth arose, they can formulate and test hypotheses about natural processes that could account for various intermediate steps, consistent with the geological evidence.

Another hypothesis, called Deep Sea Vent hypothesis, proposed by organic chemist Gunter Wachtershauser, states tha geothermal vents were a mechanism through which organic molecules were prebiotically synthesized where the superheated water containing hydrogen sulfide and metal ions mixed with the cold seawater, ultimately created a temperature gradient that allowed prebiotic synthesis and release of organic molecules. The practice questions on the quiz will test you on characteristics of the formation of Earth, as well as scientific hypotheses and experiments related to the Earth's origin.

In this article, the author analyzes systematically the work of several researchers and proposes that origin of life was primarily based on organic molecules prebiotically synthesized to form complex macromolecules as a primitive metabolism network inside cell-like structures.
