The "religion" of Chemical Evolution
The evolutionary replacement of one by another in a population.
Relating to phenomena that cannot be described by natural laws, cannot be tested by scientific methodology, and are therefore outside the realm of science.
A relationship of mutual benefit between two organisms that live together.
Speciation via populations with overlapping geographic ranges.
Living in the same geographic region.

Besides finding twice as many scientists as the Discovery Institute, NCSE added a further twist: In order to support the pro-evolution statement, evolutionists not only had to hold a PhD in science. They also had to be named Steve (or Steven, Stephen, Esteban, Stephanie, or some derivative). "Steve" was chosen for two reasons: in honor of the late Stephen Jay Gould, and because people named Steve or some variation comprise roughly 1 percent of the American population. So the Steve list could be multiplied by 100 to get a ballpark figure of how many scientists think evolution is real. Steves armed with PhDs have continued to sign up since February 2003. Steve number 300 was Stephen Hawking. On September 5, 2008, the Steve-o-Meter reached 900. On February 13, 2009, Steven P. Darwin — professor of ecology and evolutionary biology at Tulane University in New Orleans, although no relation to the most famous evolutionist — became Steve number 1,000. As of early November 2009, the Steve-o-Meter sat above 1,100. As of February 13, 2017, it sat above 1,400.

Our own ancestors took a different approach to food, which included eating meat, and even processing food through cooking and/or grinding it before sitting down to dine. In a landmark paper published in 1997, Leslie Aiello laid out the expensive-tissue hypothesis, arguing that digesting meat doesn't take as much intestinal yardage as digesting leaves, so an animal that survives on a meaty diet can get by with a smaller gut. Both the brain and the digestive tract require a lot of energy, so there has been a tradeoff between brain size and gut size, with meat eating facilitating bigger brains.

If a dog has ever snarled at you, you might have noticed its fangs, which can look menacing even in a dainty, purse-sized dog. In most, though not all, species of non-human primates, the males also have big canines. These males often fight with each other for girlfriends by showing their teeth or, worse, using them. Outside of vampire stories, humans have small canines, and one of the early signs of human ancestry is a reduction in canine size. Darwin suggested that human ancestors lost their need for big canines because walking upright freed their hands to carry weapons, and they could clobber each other instead. A more commonly accepted hypothesis today is that those free hands enabled males to bring their sweethearts useful things like food, and the ladies wisely favored the sensible, provisioning males over the hotheads. Either way, smaller canines won the evolutionary battle in hominin teeth.
What is the best evidence for chemical evolution
With degrees in science, divinity, and history, he has taught the history of science at Harvard University and at the Open University in the U.K.
The study of the form, shape, and structure of organisms.
A zoologist and professor whose research aims at understanding microevolutionary forces and macroevolutionary patterns that govern the evolution of organismal interactions, particularly the evolution of mutualisms and the evolution of social conflict and cooperation.

Life and indeed chemical evolution cannot occur on the sun or the inner planets (Venus and Mercury) because the energy is too disruptive to allow complex molecules to form for a significant length of time.
