Evolutionary biology

In the mid-1800s, Darwin and Wallace independently took careful observations of species near the South American content. And although both men were independently investigating, there are many overlaps in their observations and perspective in their respective papers – which focus on natural selection. The primary question of Darwin and Wallace’s papers were to investigate the nature of natural selection in various species and document the variation of characteristics amongst individuals in a…

he word "emotion" dates back to 1579, when it was adapted from the French word émouvoir, which means "to stir up".[1]Animal emotions have been an issue of hot discussion over the centuries with discussions dating back as early as the mid 19th century when Charles Darwin wrote about animal consciousness. Since then it has occupied many a scientist. The question is: what is the basis of assuming that non-human animals have feeling? Is it just established on the mere observation of people, or is…

What is Evolution? Many people believe that evolution is the answer to the question where life came from. This, however, is a complete misunderstanding of the actual origin of the word. The term evolution comes from Latin and literally means “the change in the gene pool of a population from generation to generation by [undergoing] different processes” (“Evolution”). This theory of evolution specifies only on the question about how life arrived at the point it has, not about the origin of life…

of larger population. For example, an endangered species with a small population can be impacted greatly by genetic drift because of a loss of genetic variation. The last mechanism of evolution is natural selection. Natural selection is an evolutionary process that occurs when a population adapts to its environment. Natural selection improves an organism’s rate of survival and reproduction in its environment. Individuals within a population may have traits that enhance survival and…

There are many reasons why he was such a great thinker such as his unique childhood/education background and how moved around so much in his fields of study. His contributions were brilliant like his book The Origins Of Species, and his field of biology has had many…

Artificial and natural selection have many similarities and differences. These two concepts were both conceived by Charles Darwin. Natural selection is defined as the process where organisms have characteristics that help allow them to adapt to environmental problems, like changes in climate, predators, or competition for food. These organisms tend to survive and reproduce in greater numbers than the other fraction of their species. This guarantees that the prolongation of those…

Charles Darwin (1809 – 1882) and Jean-Baptiste Lamarck (1744 – 1829) were both significant individuals who created their own scientific theory of evolution. Darwin and Lamarck both used the same evidence for creating theory of evolution, such as vestigial structures and artificial selection through breeding), but both naturalist, Darwin and Lamarck came up with different arguments. Darwin, on one hand had produced his scientific theory of evolution by natural selection. Charles Darwin (1809 –…

In the past years many scientist have undergone hours of research to finding what traits were passed down many family generations and the history behind genetics. Gregor Mendel came up with a theory of inheritance, he acted out on experiments that explained how dominant traits were more likely to be passed down than recessive ones. Another theory that came to place was in 1859 Charles Darwin introduced a theory of evolution among animals and plants and which he called it Darwinism. His theory…

In the story "The Time Machine" the Time Traveler theorizes about how the human race evolved into the Eloi and the Morlocks; many of these theories reflect ideas from Darwin's work. The theories the Time Traveler composes directly tie in with ideas of evolution, Natural Selection and environmental changes. First the Time traveler think that the Eloi are the only descendants of the human race; this is before he discovered the Morlocks. He believes that scientific progress continued to make…

Evaluate the impact of increased understanding of the fossil record on the development of scientific ideas about the history of life on Earth Improved understanding of the type of fossilised arthropod known as a ‘Trilobite’ allowed for subsequent increases in development of the theory of evolution. Since it’s initial drawing by Rev. Edward Llwyd in 1698, multiple improvements in technology as well as collection of specimens have painted a detailed portait of the nature of trilobites as well as…
