What Are the Major Theories of Biology?

The major theories of biology have been tested over years and provide information helping you to understand the science of biology. For each theory, list the name of the person or persons known for scientifically testing each theory, the approximate date they experimented with the theory, and a sentence or two to describe the theory.

Bioenergetics:
Theory by Antoine-Laurent Lavoiser in the late 18th century, the unique network of chemical reactions in cells was an important experiment from this principle.

Biological classification:
Theory by Carolus Linneau in the late 18th century, Linneaus classified living organisms according to their similarities and differences. We now use Darwins theory of evolution.

Cells:
Theory by Matthias Schleiden and Theodor Schwann in the 17th century, found that the cell is the smallest unit capable of exhibiting all of the characteristics of life. All organisms are made up of cells that come from preexisting cells.

Ecosystems:
This theory has no ready identifiable parent from the 20th century and states if change happens in any part of the biological community it causes change in other parts. Organisms interact with one another and with their environments.

Evolution by natural selection:
Theory by Charles Darwin in 1859, he published a book titled The Origin of Species. He was the first person to propose a scientific explanation about the diversity of life which is broke into two parts; species and natural selection.

Homeostasis:
Theory by Claude Bernard in the mid-19th century, a study was done that showed that a person functions best when their internal conditions are maintained. For

    Evolution by natural selection: This theory came about as a result of Charles Darwin trying to find an explanation for “why there are so many different living beings on earth?” (Pruitt, N. L., & Underwood, L. S. (2006). His theory contains two parts, the first part states that species change over generations. The second part states that what causes this change is natural selection.…

    This theory states that everything existed as a speck or “seed” of themselves. The seeds came from all over the universe and traveled through space from one location to another. Some people believe this is how life on Earth began. There are three variations of this hypothesis. They are Interstellar (flying rocks from other planets spread the seed material from one solar system to another), interplanetary (Seeds are spread one planet to another in the same solar system, and Directed panspermia (spreading of seeds from extraterrestrials to Earth). Recent Indian and British researchers were able to get samples from the stratosphere that contained living cells. Another example to support this theory is another scientist found extraterrestrial bacteria inside a meteorite that scientists think is over four-billion years old. Anaxagoras reasoning behind his theory is that he wondered why flesh isn’t made out of flesh and where did we come from? So he answers himself saying a being from another world made us and put us here. Different scientists have tested this panspermia hypothesis by sending microbes into space and seeing if they can stand reentry into earth’s…

    Both of these show the distribution of phenotypes. In directional selection, the distribution of phenotypes forms a "bell curve." Selection against one of the extreme phenotypes causes the distribution to move in one direction or the other. An example might be plants whose flower color is determined by incomplete dominance: white, pink, or red. Pink flowers may be the average phenotype, but if we start to remove red flowers from the population, the "mean" phenotype will be shifted toward white flowers.…

    Our bodies have processes that happen to keep everything at an even rate. If things get out of balance our bodies tries to bring them back into balance. Homeostasis refers to the processes of keeping internal body environment in a steady rate, when the external environment is changed. The aim of this essay is to discuss the internal environment, the importance of regulation of core temperature, negative feedback and positive feedback and contrast control of core body temperature in normal conditions and in hypothermia.…

    Charles Darwin in 1859 published On the Origin of Species, he explained his theory of evolution. He presented evidence that would further explained his reasoning. The first Darwin looked at the fossils and looked at the geological layers. Next compared the structural of the human hand, bird wing, and a cat paw and hinted that we come from common ancestors. His finally observation was the dramatic change in domestic plants and animals by selective breeding. Darwin believed that species started to change their structure, psychology, and behavior that would help with…

    We will first start with the theory of evolution. Charles Robert Darwin, was born on the 12th of February 1809, and is the founder of evolutionary theory. He initially planned to follow a medical career, and studied medicine, but later switched to divinity. In 1831, he joined a five year scientific expedition on the survey ship, HMS beagle. While on the ship, Darwin read Lyell’s ‘Principles of Geology’ which suggested that the fossils found in rocks were actually evidence of animals that had lived many thousands or millions of years ago. But, Lyell’s argument was instated and reinforced in Darwin’s own mind when the ship reached the Galapagos Island. Here he observed the rich variety of animal life and this is where the inspiration for his theory came. Darwin noticed that each island supported its own form of finch; they were closely related between islands but had key differences. On Darwin’s return, he…

    Charles Darwin provided a mechanism for the theory of Biological Evolution, which is what separates him from previous researchers. Before Darwin’s theory of biological evolution by natural selection, the ancient Greeks were the first to attempt to understand our place in the natural world. Following the Greeks, was Aristotle, he believed that each living form had attributes that could not be altered, therefore, fitting in an ordered rank ladder, and that human beings were at the top of the ladder. Before the 19th century most naturalist believed that there was a single creation event—influenced by the church’s beliefs (Stanford 17). Even then, naturalists continued to develop classifications for animals and plants. John Ray was the first to…

    Charles Darwin first introduced evolution by the fact of natural selection in 1859. Natural selection is the environmental process in which the organisms that are better suited for their environment will survive and reproduce, but the organisms that are not better suited for their environment will die and not reproduce. Natural selection is one of the supportive factors to the idea of evolution. It is true that organisms change over time, but they cannot change based on their own desire to survive. Their species changes through generational adaptations. Evolution, the idea of the origins and original developmental occurrences of the world and the organisms within the world, is based on natural selection because natural selection explains the…
