Alfred Wegener and the Continental Drift

- ... In 1912 he first introduced the theory of the continental drift at a conference in Germany. He theorized that the continents had moved away from each other over a period of time and denied that land-bridges had existed to connect the continents. The same year he married the daughter of a meteorologist and returned on another expedition to Greenland. He went on to serve in the military during World War I. Although the idea about the continental drift had never gone away it wasn’t until 1915 that he published his theory....   [tags: meteorology and astronomy]

The Hypothesis Of Genetic Drift

- Emlen and Zimmer discussed that one of the foundations for the null hypothesis from which Kimura was a big advocate lies on the fact that genetic drift could be at times the sole responsible for evolution (even if natural selection does not occur). It wasn’t until the second half of the 1960s that Kimura established his whole neutral evolution theory; nevertheless, it is well known that mutations can often bypass the action of selection. In other words, it is known that selection works to increase fitness potential in individuals, but there are some types of mutations that don’t affect the fitness whatsoever....   [tags: Natural selection, Evolution]

Genetic Drift and HIV

- Genetic drift can completely eliminate an allele from a population. Genetic drift is one of the mechanisms of evolution, along with descent with modification, mutation, migration, and natural selection (Mechanisms: The Processes of Evolution). Benefits and drawbacks can come from genetic drift. When a population's genetic makeup is changed randomly, it is called genetic drift.

How do Groynes Prevent Longshore Drift

- To determine how groynes prevent longshore drift. The issue: Longshore drift influences the deposition and erosion of sediments. Waves erode the coast and transport the eroded material along the coastline. Over a period of time, the material will be deposited on a beach or form a larger feature such as a spit. Groynes are structures built at equal intervals along the coastline. Their purpose is to restrict longshore drift, preventing coastal erosion.

Factors Of Natural Selection : Genetic Drift And Fertility

- Introduction: The main purpose of this lab was simply to study two factors of Natural Selection: Genetic Drift and Fertility. The first of these factors in the study was Genetic Drift. In this section of the lab, there was one main question to answer: What effect does population size has on random mechanisms. For this question, I hypothesized that if the population is smaller, then the random mechanisms will have a greater effect on the populations. I believed that this was because basic math principles would allude to the idea that any bad random mechanism to a small population would harm a greater percent than a larger population....   [tags: Demography, Population, Fertility]

The Continental Drift Theory And Plate Tectonics Theory

- Background The continental drift theory and plate tectonics theory was first put forward by the German geologist and meteorologist Alfred Wegener at the beginning of the 20th century. He proposed that there was a single continental in 200 million years ago, and the Earth’s crust slowly separate to pieces by the centrifugal pseudo force because of the rotation of the Earth. On the basis of plate tectonics theory there are two components in the Earth which are lithosphere and asthenosphere, the upper layer is lithosphere and the lower layer is asthenosphere....   [tags: Earthquake, Plate tectonics, Seismic hazard]

The Changing Of Allele Frequencies Within A Population

- The continuous changing of allele frequencies within a population corresponds to a change in phenotype over time. These changes in phenotypes are documented as different evolutionary points within a species. From this we can observe that a new allele has the potential to create evolutionary change within that population. These new alleles can change in frequency due to genetic drift, mutations, migration, natural selection or assorted mating. Natural selection for, or against a new allele, determines its fate within the population....   [tags: Evolution, Natural selection, Genetic drift]

- The Hardy-Weinberg theorem states that the frequency of alleles and genotypes in a population’s gene pool remain constant over the generations unless acted upon by agents other than sexual recombination. For example, take a population of mice that consists of 1,000 members. A specific allele, albino allele, is recessive within this species. 80% of the population expresses the normal phenotype- brown coloring, while the remaining 20% are albino. 640 members of the population have the genotype AA, 320 have Aa, and 40 have aa....   [tags: essays research papers]

The Evolutionary Divergence Between Humans, Chimpanzees, And Bonobos

- Over generations, there were patterns of evolution, which allowed species to go through adaptation and variation. The microevolutionary force of allele frequency changes led to the evolution of reproductive barriers between subpopulations. The modern synthesis helps us to understand human evolution and both the microevolutionary and macroevolutionary patterns. In order to explain the speciation between humans (Homo sapiens), chimpanzees (Pan troglodytes), and bonobos (Pan paniscus), we need to recognize that one factor alone cannot demonstrate the entire nature of adaptation or human evolution....   [tags: Evolution, Population genetics, Genetics, Human]
