Dr Charles Darwin s Theory Of Evolution - amusing

Darwin's theory of evolution should be expanded to include consideration of a DNA stability "energy code" - so-called "molecular Darwinism" - to further account for the long-term survival of species' characteristics on Earth, according to Rutgers scientists. The iconic genetic code can be viewed as an "energy code" that evolved by following the laws of thermodynamics flow of energy , causing its evolution to culminate in a nearly singular code for all living species, according to the Rutgers co-authored study in the journal Quarterly Reviews of Biophysics. Breslauer, Linus C. The origins of the evolution of the DNA genetic code and the evolution of all living species are embedded in the different energy profiles of their molecular DNA blueprints. Under the influence of the laws of thermodynamics, this energy code evolved, out of an astronomical number of alternative possibilities, into a nearly singular code across all living species.

Theory of Evolution: How did Darwin come up with it? - BBC News

Nearly years ago, Charles Darwin wrote a personal letter to a friend and laid out the scaffolding of what would later be called primordial soup theory : Basically, Earth's original blend of gases produced a broth of organic molecules when exposed to light and heat, eventually forming the building blocks of life in amino acids. Now, research scientists are lining up more and more evidence that he was probably right. So do we. Let's nerd out over it together. Not only did Darwin suggest an overall primordial soup—he identified some nuanced ways that a smaller, closed body of water would make a better mix.

In an letter to a friend, Darwin wrote :. With enough amino acid pieces swirling in the same body of water, scientists believe, almost all combinations will end up occurring. The million read more have turned to stirring the soup. There are some key factors here that scientists now believe are critical to a successful primordial soup. And, honestly, you can think of it like a regular soup. Imagine throwing one bouillon cube into an entire stockpot versus a small saucepan full of water. Not only will your stockpot full have very little flavor, it will take forever for the water to heat enough for the bouillon cube to dissolve all the way.

It will even be more difficult to pin down remaining pieces to break up with a wooden spoon. That means a primordial soup with all the same ingredients like different amino acids and Preventing Teenage Pregnancy will respond very differently to sunlight on a small pond versus a large ocean. And, as Dr Charles Darwin s Theory Of Evolution BBC points outeven the size of a small pond varies from day to night and from season to season, making a kind of running experiment that iterates the same materials at every possible concentration and condition:.

One incredible thing is that, as with his understanding of even basic concepts about heredity and evolution, Darwin did a pretty good job reverse engineering hugely complex ideas without almost any of the scientific Evolutuon blocks we know about now. If they ever do, that technology will join existing synthetic biology Charlrs human-made viruses and bacteria, opening up a new world of artificial lifeforms and the ethical questions that follow.

For now, researchers will keep gently agitating mixtures of aminos and other chemicals. And forget Nosferatu—the forward-looking work of icons like Leonardo da Vinci and Charles Darwin is spooky enough sometimes.

Recreating the soup requires sophisticated chemistry as well as chemical history. Darwin made an incredible educated guess considering the body of knowledge he was working with.
