small group from a particular population migrates to a new region and establishes a whole new population. This new population has no interbreeding action with the parent group but with different groups. This leads to a different allele frequency and speciation. The new population has different genotype and phenotype from the parent

Anthropology is the study of human beings‚ in particular the study of their physical character‚ evolutionary history‚ racial classification‚ historical and present-day geographic distribution‚ group relationships‚ and cultural history. Anthropology can be characterized as the naturalistic description and interpretation of the diverse peoples of the world. Modern-day anthropology consists of two major divisions: cultural anthropology‚ which deals with the study of human culture in all its aspects;

thus creating species variation. It discusses how at first‚ the primates are very primeval & this was largely due to their restricted diet. Secondly‚ it talks about the way in which they started to develop a more diverse diet and this resulted in speciation and also was related to natural selection. Lastly‚ it explains how their change in diet largely affected their brain size and cognitive functions enabling them to develop mentally as a species. From the beginning‚ Howler monkeys have had many

Extinction and Evolution Ecology helps us understand the importance of mass extinction in evolution‚ and it also helps us understand some of the causes of extinction. Ecological niche is one of the most important concepts to understand. An animal or plant lives in a certain place is active at a particular times‚ and eats certain things; all these factors describe its ecological niche. Our environment is parted into millions of ecological niches‚ each that represents a probable home for life

further illustrate‚ some genetic changes in populations do result in the appearance of a new species‚ also known as speciation‚ and particularly seen when those populations are isolated from each other (Jurmain et al. 5). This level of evolution is known as macroevolution. On the other hand‚ there are genetic changes within a given population and while these changes may not lead to speciation it can cause populations of a species to vary from one another in the frequency of specific traits. Evolution such

obviously be alive somewhere. Nowadays‚ that wouldn’t happen and the word “extinct” is very familiar. Lamarckism compared to Darwinism Jean-Baptiste Lamarck (1744-1829) and Charles Darwin (1809-1882) were both interested in the diversity of life and speciation. Lamarck is known for his Theory of Inheritance of Acquired Characteristics‚ first presented in 1801. If an organism changed during life in order to adapt to its environment‚ those changes would be inherited by offspring. Lamarck believed that

Unit 1 KEY QUESTIONS 1. what was the original purpose of Darwin’s voyage on the H.M.S. Beagle‚ and what was the ultimate significance of the Voyage? The original purpose of Darwin’s voyage was to learn and discover more about biology and to gain insight on plant and animal species. The stated intent of the voyage was to obtain evidence that supported the biblical theory of creation as well as chart poorly known parts of the South American coastline. 2. Why does the Antibiotic resistance problem
