Tips for writing your first scientific literature review article BY Emily Crawford Emily Crawford often retreated to her apartment rooftop in San Francisco to write her review. Photo courtesy of Matthew Perry. When I undertook the task of writing a scientific literature review article last year, I had hoped that a Google search would reveal a handful of how-to pages thoughtfully created by veterans of this particular writing process. I found nothing of the sort, so I plowed ahead on my own, inventing techniques for myself.

18 Complicated Scientific Ideas Explained Simply | Mental Floss

General overview The evidence for evolution Darwin and other 19th-century biologists found compelling evidence for biological evolution in the comparative study of living organisms, in their geographic distribution, and in the fossil remains of extinct organisms.

The amount of information about evolutionary history stored in the DNA and proteins of living things is virtually unlimited; scientists can reconstruct any detail of the evolutionary history of life by investing sufficient time and laboratory resources. The following sections identify the most productive of these sources and illustrate the types of information they have provided.

The fossil record Paleontologists have recovered and studied the fossil remains of many thousands of organisms that lived in the past.

This fossil record shows that many kinds of extinct organisms were very different in form from any now living. It also shows successions of organisms through time see faunal succession, law of ; geochronology: Determining the relationships of fossils with rock stratamanifesting their transition from one form to another.

When an organism dies, it is usually destroyed by other forms of life and by weathering processes. On rare occasions some body parts—particularly hard ones such as shells, teeth, or bones—are preserved by being buried in mud or protected in some other way from predators and weather.

Eventually, they may become petrified and preserved indefinitely with the rocks in which they are embedded. Methods such as radiometric dating —measuring the amounts of natural radioactive atoms that remain in certain minerals to determine the elapsed time since they were constituted—make it possible to estimate the time period when the rocks, and the fossils associated with them, were formed.

Radiometric dating indicates that Earth was formed about 4.

Indeed, research on the topic of sexual orientation offers a powerful window into understanding human sexuality.
Mathematical and theoretical biology - Wikipedia Race historical definitions During the Age of Enlightenment an era from the s to the sconcepts of monogenism and polygenism became popular, though they would only be systematized epistemologically during the 19th century. Monogenism contends that all races have a single origin, while polygenism is the idea that each race has a separate origin.

The earliest fossils resemble microorganisms such as bacteria and cyanobacteria blue-green algae ; the oldest of these fossils appear in rocks 3. The oldest known animal fossils, about million years old, come from the so-called Ediacara faunasmall wormlike creatures with soft bodies.

Numerous fossils belonging to many living phyla and exhibiting mineralized skeletons appear in rocks about million years old. These organisms are different from organisms living now and from those living at intervening times.

Some are so radically different that paleontologists have created new phyla in order to classify them. The first vertebrate s, animals with backbones, appeared about million years ago; the first mammal s, less than million years ago.

The history of life recorded by fossils presents compelling evidence of evolution. The fossil record is incomplete. Of the small proportion of organisms preserved as fossils, only a tiny fraction have been recovered and studied by paleontologists.

In some cases the succession of forms over time has been reconstructed in detail.In , Randall Munroe of the webcomic xkcd published a description of the Saturn V rocket using only the most frequent words in English.

Article Summary: Here's a clear summary of the Linnean system of binomial nomenclature, the scientific way to name living things with a two part generic (genus) and specific (species) name. Evolution: Evolution, theory in biology postulating that the various types of plants, animals, and other living things on Earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations.
