Hypothesis and options are used in the description of beliefs.

When and the wiped out nearly everything, long years of evolution on separate continents came to an end when one supercontinent formed and became Earth’s dominant land animal for a brief time. The was another example of merging continents spelling the extinction of less adaptable species. Some have argued that the biological effect of Europe’s conquest of the world was like continents merging,

This is just a brief example of scientific method.

The study of the flow of real fluids through tubes is of considerable interest in physics and chemistry as well as in biomedical science (flow of blood in arteries) and in engineering. Engineers have to keep water moving in pipes to supply cities with drinking water, and to take waste water away. They know that the speed of the water depends on the viscosity, the diameter of the pipe, the length of the pipe and the pressure difference. Poiseuille's Law quantifies these quantities in the formula: Q = πR4ΔP / 8ηL. You can look this up to find out what the symbols mean.

Another key set of tensions are those between theorists, empiricists, and inventors. Theorists attempt to account for scientific data and ideally predict data yet to be adduced, which tests the validity of their hypotheses and theories. often produce that scientific data. Inventors create new technologies and techniques. Albert Einstein is the quintessential example of a theorist, who never performed experiments relating to his theories but accounted for experimental results and predicted them. , who performed the experiment that produced results that various scientists wrestled with for a generation before Einstein proposed his , never suspected that their experiment would lead to the theories that it did. The most important experiments in science’s history were often those producing unexpected results and were usually called failures. Einstein’s had no experimental evidence when he proposed it (it , but that was the only evidence for it when the theory was proposed), but it has been confirmed numerous times since then. Einstein expected that his theories would eventually be falsified by experimental evidence, but that the best parts of his theories would survive in the new theories.

For example, if I were to try to start my car and it doesn’t work, my first reaction would be to think of reason my car is not starting.

Wrangham made the ability to sleep on the ground a key part of his Cooking Hypothesis. was not only adapted for ground living, , which would have reflected eating soft and easy-to-digest food. Along with organ meats, cooked food is the leading candidate for soft foods. If habilines mastered fire, they would have almost immediately used it for cooking.

Some hypotheses are stronger, others weaker, and some have already come and gone (and might be resurrected one day, as was?). The coming generation of research may resolve most of these issues, but new ones will undoubtedly arise and there is obviously a long way to go before significant consensus will be reached on those ancient events.

Some scientists treat every proboscidean extinction as a unique mystery, unrelated to other proboscidean extinctions, and climate and resulting vegetation changes are hypothesized as agents of extinction (or other causes invoked), when the most probable cause stares at them each morning in the mirror. The devil in the details, but regarding the megafauna extinctions, some specialists cannot seem to discern a very clear pattern. Scientists, because they are human, have an inherent conflict of interest when attributing such catastrophes to non-human causes. During the remainder of this essay, it will become evident that there is a human penchant for absolving one’s in-group of responsibility for catastrophes and crimes committed against the out-group, and , scientists, and other professionals regularly engage in such interest-conflicted acts, whether they were defending their species, race, gender, nation, class, ideology, ethnicity, or profession. That in-group/out-group difference in treatment has a long history and probably goes back to the beginnings of territorial social animals.
