Sexual selection

took into great consideration what organisms lived where and the circumstances surrounding them. This helped him understand why creatures are what they are and where they are. Darwin believed in evolution through the process of natural selection. Natural selection is where all organisms transform in their physical features and behavioral traits over long periods of time in order to become more successful in their native environment, this is also known as survival of the fittest. It is believed…

How have seahorses adapted to better survive in their habitat? Adaptation is a process by which an organism gradually changes over generations to better survive in its environment. These changes can be structural, or physical; or they may be behavioral, or related to the animal’s behaviors. Spotting a sea horse in its natural habitat is a tricky treat for SCUBA divers. These fish are masters of disguise. They can change colors to camouflage themselves, and feature bumps called tubercles that…

The brave new world book was written by Aldous Huxley where he created and illustrated a fictional world that everyone is cloned, classified since birth into Alpha, Beta, Gamma, Delta, Epsilon. In Huxely's argument, In that society, humans are genetically reproduced and are conditioned to serve a ruling order. In this society disease, poverty, and suffering has disappeared from Earth. The different types of people of the book have similarities and differences compared to our present society.…

universe and life originated “from specific acts of divine creation” (“Creation Tips”). But, how can that be true when you have physical evidence such as Fossils, DNA, and natural selection? In theory, evolution is a more logical and believable argument than creationism because evidence such as fossils, DNA, and natural selection can support the theory much better than a book that has been translated into different languages. Evolution can be seen in almost every living thing,…

forces of evolution are mutations, natural selection, genetic drift, and gene flow. Mutations are changes in genes that make us who we are today. Mutations, although they are changes in our genetic code, are most of the time harmless and essential to evolution. Mutations can be either advantageous, deleterious, or neutral depending on what the environment of the living organism is (class lecture, Wednesday). The next force of evolution is natural selection which is the idea that favorable traits…

This experiment is a hypothetical representation, modelling the effects of colour mutations in “prey” and vision mutations in “predators”, and their role in natural selection. This means that different materials in this experiment represent real-life organisms and environments. The sand-coloured background represents a sand environment, while the green background represents a grass environment. The individual conducting the experiment is acting as the “predator” (bird) and the tweezers used by…

The four forces of evolution include mutation, gene flow, genetic drift, and natural selection. Mutation occurs when the base pairs in DNA change which leads to different codons being read during translation. Most mutations create codons for the same amino acid that the normal codon would have made but sometimes a different amino acid is made and that leads to changes in the organism's phenotype. Gene flow happens when two different populations come together and reproduce with each other. The…

traits of species can be passed down from one generation to the next. One of the main differences is that these traits were not derived from the environment shaping the organism’s genetic ability but from the chance of mutations and natural selection. “Natural Selection,” meaning the process whereby organisms better adapted to their environment tends to survive and produce more offspring. Darwin’s observations have a slighter variation between creatures of the same species which may give an…

Darwin’s theory of Evolution, was that they didn’t believe that Natural Selection was the main driving force of Evolution. Everyone at this point, even theologians, accepted Evolution. However, since a lot of people disagreed with Natural Selection, this gave rise to different alternatives to explain the variations of species. Additionally, many naturalists who came up with the different alternatives, the methodology of Natural Selection didn’t appeal to them because it was immoral for an…

Natural selection is the main scientific method of evolution and the precursor to an organisms transformation over a scale of time. In natural selection organisms that survive have heritable traits that aid in reproduction thus becoming prevalent in that organisms population. Jurmain(2013) explains in our textbook, that, through the aid of Thomas Malthus ideas, Charles Darwin was able to grasp the explanation of selection in nature (page40). Jurmain(2013) states “In the struggle for existence,…
