PPT-Origin and history of life

Origin of Life Darwins theory is based around the idea of a common ancestor that all living organisms can be traced back to This ancestor is called the Last Universal Common Ancestor or LUCA .

Meara. EEB464 Fall . 2015. I place in a glass flask the following liquids or infusions, all very alterable on contact with ordinary air: beer-yeast water, sugar-beer-yeast water, urine, beet juice, and pepper water; then with the aid of a lamp, I draw the necks of the flasks to give different shapes. I then bring the liquid to a boil for a few minutes until the water vapors leave abundantly by the end of the drawn-out neck.... I then let the flasks cool. A strange thing happens that will astonish everyone accustomed to the delicacy of experiments relative to so-called spontaneous generation;... the liquid in the flasks remains indefinitely without alteration.. “…sparked by just the right combination of physical events & chemical processes…”.
