The Miller-Urey Experiment Harold Urey proposed a series of conditions, which, if present on prebiotic Earth, would have been conducive to the origins of life on Earth. Stanley Miller later proved that these conditions were favorable for the synthesis of simple amino acids, which was the beginning of a series of experiments, modeled on this notion of prebiotic Earth, that created other more complex molecules needed to support life. Using the hypothesis set up by Urey and tested by Miller, this
“Watch your thoughts, for they become words; watch your words, for they become actions; watch your actions, for they become habits; watch your habits, for they become your character; and watch your character for it becomes your destiny” (Donyes np). The simplest things such as our thoughts and words can impact who we become. Throughout life we become a product of our experiences. Kanakuk was one of those experiences that has changed my destiny. I could never imagine how this two-week long summer
to evolve not the few days that were described in the bible. Therefore the story of creation according to genesis is widely discredited by scientists. Personally as a scientist I believe that life was created by chemical means as proven by Miller. However I do not believe that this was a totally scientific process I think that it was someway controlled or perfectly arranged by a divine influence. So overall I would place myself in the theistic evolution category.
long been debated about. In result to that there are many hypotheses that each claim that’s how life started. Some of them claim life came from space, others from clay and even hydrothermal vents. However, they’re only theories which is why many experiments and research going into proving them. Many great minds such as Alexander Oparin, Gunter Wachtershauser, Robert Vrijenhoek and Louis Pasteur are the brains behind the hypotheses which is what makes them even more interesting to test out. The hypotheses
that life on Earth began in the water. Jack Corliss’ big discovery changed his, and other scientist’ thoughts about where life on Earth might have begun, because it proved possible that in the hydrothermal vents, is where life could have begun. The experiment conducted by Jay A. Brands and the Carnegie Institution of Washington, D.C., put minerals and water into capsules with a bomb. This allowed it to disperse when it was at the bottom of the ocean. Brandes was trying to figure out if chemical reactions

form amino acids to form the first life forms. Later, in 1953, Stanley Miller and Harold Urey tested the hypothesis with an experiment known as the Miller-Urey experiment, which included gases from a reducing atmosphere, a simulation of an ocean, and lightning strikes to cause the organic compounds to form. This experiment did show that the compounds formed in this environment. Scientists later found flaws with the experiment, such as they simulated constant strikes of lightning, but lightning strikes

molecule was born in the atmosphere. The molecule was energized with lightning and rain making “organic soup”. The first organisms would have to be simple heterotrophs in order to survive. To test this theory Chemist Stanley Miller and Physicist Harold Urey did a famous experiment in 1950. Mixing Methane, Ammonia, Water, and Hydrogen. Then the sparked the mixture to signify lightning. The result was amino acids. The Panspermia Theory The Panspermia theory suggests life seeds came from outer space
Allison Yi 1/19/17 AP BIO Section number 132 Theories for the Origin of Life on Earth 1. The Panspermia theory is a theory that suggests that life on Earth started due to a meteorite colliding to Earth and that life did not start on Earth. The theory explains that life was existent in space and that there was a bacteria that was able to travel in space in a meteorite. 2. A. The Chemical evolution theory states that early
The Absurdity of Scientific Creationism We humans have always thought of ourselves as being unique, whether by divine sanction or by a self-established belief in superiority. For some, this understanding is intimately tied to the traditional tenets that have long been held as fact, having only recently been challenged. For modern Christians, the literal interpretation of the Bible=s account of creation has come under attack by the development and widespread acceptance of Darwinian evolution
