Carl Edward Sagan, Ph.D. (1934-1996) was an American astronomer, astrochemist, author, and highly successful popularizer of astronomy, astrophysics and other natural sciences. He pioneered exobiology and promoted the Search for Extra-Terrestrial Intelligence (SETI).

He is world-famous for writing popular science books and for co-writing and presenting the award-winning 1980 television series "Cosmos: A Personal Voyage", which has been seen by more than 600 million people in over 60 countries, making it the most widely watched PBS program in history.

A book to accompany the program was also published. He also wrote the novel "Contact", the basis for the 1997 Robert Zemecki's film of the same name starring Jodie Foster.

During his lifetime, Sagan published more than 600 scientific papers and popular articles and was author, co-author, or editor of more than 20 books. In his works, he frequently advocated skeptical inquiry, secular humanism, and the scientific method.

The Origin of Life - Abiogenesis - Dr. Jack Szostak

This has been CONFIRMED in Dr. Jack Szostak's LAB. 2009 Nobel Laurette in medicine for his work on telomerase.

It's been 55 years since the Miller-Urey Experiment, and science has made enormous progress on solving the origin of life. This video summarizes one of the best leading models. Yes there are others. Science may never know exactly how life DID start, but we will know many ways how life COULD start. Don't be fooled by creationist arguments as even a minimal understanding of biology and chemistry is enough to realize they have no clue what they are talking about.



Note on how competition works. Water will flow across a membrane to try to equalize the ion concentration. If there is a lot of polymer in a vesicle it will be surrounded by many ions, thus causing water to flow into the vesicle, increasing the internal pressure and stretching the membrane. Fatty acids are in equilibrium between the vesicle and solution. If 2 vesicles are near one another they will gradually swap fatty acids. If one membrane is under tension, the fatty acid "on rate" will be greater than the "off rate" (move to a lower energy state by relaxing the pressure). It will suck up fatty acids from solution. The other vesicle will still give them off, but they will disappear (sucked up by neighbor) and not return. Therefore, the vesicle with high internal pressure will grow and the neighbor will shrink.
