Who do you think of when a person says “evolution”? Charles Darwin probably came into your mind first‚ didn’t he? Surprisingly‚ Darwin is not the only evolutionary theorist‚ as there are two others with similarly different ideas. Jean-Baptiste Lamarck‚ Alfred Russel Wallace‚ and Charles Darwin all investigated this field of science. Jean-Baptiste Lamarck was the first to have extended theories of evolution. In 1794‚ Lamarck started working in the natural history museum‚ Jardin des Plantes‚ and

methicillin-resistant strains appeared soon‚ and by the 1980s those strains were widespread. Vancomycin became the next great weapon against staph‚ and the first vancomycin-resistant strain emerged in 2002. These antibioticresistant strains represent an evolutionary series‚ not much different in principle from the fossil series tracing horse evolution from Hyracotherium to Equus. They make evolution a very practical problem by adding expense‚ as well as misery and danger‚ to the challenge of coping with staph

The Role of Primate Sociality in Evolutionary Theory Introduction Some animals‚ and more specifically primates‚ have been noted for having brains of an uncommonly large size. One explanation for this phenomenon is the ‘social brain’ or ‘social intelligence’ hypothesis‚ which states that brain sizes have increased in order to handle the demands of sociality (Lindenfors 2005; Pérez-Barbería et al. 2007). The increase in brain size can be attributed to the computational power needed to track

SCI 230 Week 1 Checkpoint Theories of Biology.doc The Major Theories of Biology 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

Biology 42: Lab 22 Selection & Microevolution Name ____________ Introduction: Using the Hardy-Weinberg Equation/Looking at Microevolution What are the factors that lead to evolutionary change? Using mathematical equations‚ Hardy & Weinberg in the early 20th century showed that evolutionary change – measured as changes in allele frequencies in a population from one generation to the next – will not occur unless certain kinds of “evolutionary agents” are affecting the population

subtle. The tail of a peacock is an exhausting and dangerous thing for the bird to grow. It can only be done well by the healthiest males: parasites‚ starvation‚ and careless preening will result in duller plumage. So bright plumage constitutes what evolutionary biologists call an "honest indicator of fitness." Substandard peacocks cannot fake it. And peahens‚ by instinctively picking the best males‚ thereby unknowingly pass on the best genes to their offspring. Darwin aslo said that sexual selection

Herbert Spencer’s Influences and Contributions to Sociology Herbert Spencer has contributed to various fields of knowledge like philosophy‚ biology‚ psychology‚ anthropology and sociology. Herbert Spencer is popularly known for his treatment of evolution. The evolutionary doctrine was no doubt the foundation of Spencer ’s sociological theory. He‚ however‚ presented the organic analogy‚ a secondary doctrine which also played a vital role in his thought system. He identified society
