Evolution Of A Large Mammal s Life Cycles - 1081 Words

Fossils are considered to be evolutionary markers that records a lineages of creatures across time — providing a distinct way to compare different species. When Darwin set forth on a journey to the Galapagos Islands, he discovered many aspects of evolution. During his expedition, he discovered the fossils of creatures which closely resembled the modern armadillos. At that time, Darwin did not possess any tools or resources to predict the phylogenetic lineages and the evolutionary history of the armadillos. However, using modern day science and techniques like DNA and protein sequencing, it is now possible to better understand the relationships between different organisms. Furthermore, by observing the early developmental (embryonic) stages of a large mammal’s life cycles it is possible to indicate the relationship of the mammals with other mammals6. The combination of these methods may lead us to determine the phylogenetic position of armadillos Dasypodidae and other r elated organisms, such as anteaters and sloths. Armadillos’ evolutionary history has been a subject of many controversies and has been revised multiple times. Nevertheless, new developments in sequencing have allowed us to better understand the evolutionary relations using the DNA and proteins found in the fossils. By the use of these techniques, we are able to see the points of similarities among different species of armadillos. Furthermore, we can produce a phylogenetic tree to see the divergence ofShow MoreRelated Animal Testing and Researching Essay1035 Words   |  5 PagesResearching Animal testing is supported by some, but opposed to others. The growing number of animals used in research differs among the different countries. The fruit fly and nematode are the most used animal in testing. However, the most common mammals used in animal research are mice and rats. Shaved albino rabbits and guinea pigs suffer severe testing for skin irritancy and eye irritancy. Though the usage of non-human primates are outlawed in some countries, the U.S. still finds the need to useRead MoreEvolution And Evolution Of Evolution1514 Words   |  7 PagesEvolution is defined as a genetic change in population or species over generations. Evolution by natural selection is a very important concept in biology since it lays the foundation of evolutionary thought of how organisms have developed gradually over a long period of time. The ideas of evolution were not accepted until Charles Darwin published his book â€Å"On the Origins of Species by Means of Natural Selection† in 1859 . Before the evolutionary thought, people believed that all organisms were createdRead MoreIntroduction to Evolution3680 Words   |  15 PagesIntroduction To Evolution What is Evolution? Evolution is the process by which all living things have developed from primitive organisms through changes occurring over billions of years, a process that includes all animals and plants. Exactly how evolution occurs is still a matter of debate, but there are many different theories and that it occurs is a scientific fact. Biologists agree that all living things come through a long history of changes shaped by physical and chemical processes thatRead MoreThe Sixth Extinction Reflection1065 Words   |  5 Pagesenvironmental health. Basically, the author handled its large, weighty ideas by comparing the current environmental issues with the past five major episodes of mass extinction. Nowadays, the world’s undergoing a sixth mass extinction period, with humans as the driving factor. In short, industrialization and globalization have ushered in a new epoch in Earth s history. People are significantly altering the Earth’s land, ocean, atmosphere, and life in a way that â€Å"no other creature has ever managed.† ARead MoreEssay about Creation vs Evolution2018 Words   |  9 Pagescreated by God during his creation of the universe. This is the idea of creationism. It is supported by many religious people. Creationism is supported by religion. The second way that humans could have originated is through a process called evolution. Evolution is a theory proposed by scientists to explain the origin of a ll species. Because both explanations are theories, neither can be proven right or wrong. To make a decision on which theory is correct, people must choose either religion or scienceRead MoreGuinea Grass And The Mango Tree1627 Words   |  7 PagesCape buffalo are massive creatures; they weigh one ton and stand five feet above the ground (Estes). A Cape buffalo’s diet consists of grass and other vegetation; therefore, they are herbivores. Cape buffalo belong to the genus Syncerus and species S. caffer. The Cape buffalo contributes to the ecosystem by consuming grasses and then converting them into decomposable excrement. The Cape buffalo also servers as potential food for secondary consumers and tertiary consumers. Consumers are vital to anRead MorePredator - Prey Relationships4420 Words   |  18 Pagesdifferent relationships between predator and prey; focusing on the symbiotic relations between organisms, the wide range of defense mechanisms that are utilized by various examples of prey, and the influence between predators and prey concerning evolution and population structure. Symbiosis is the interaction between organisms forming a long term relationship with each other. Many organisms become dependent on others and they need one another or one needs the other to survive. Symbiotic interactionsRead MoreDynamic Biological Processes Influence Pop, Density, Dispersion, And Demographics1863 Words   |  8 Pagesfavor germination growth Mushrooms, may be clumped within on top of a rotting log Insects salamanders may be clumped under same log because of the higher humidity there May also be associated with mating behavior Mayflies often swarm in great #s, a behavior that increase their chance of mating Uniform - evenly spaced, pattern of dispersion may result from direct interactions between individuals in the pop. Some plants secrete chemicals that inhibit the germination growth of nearby individualsRead MoreRespiratory System9190 Words   |  37 Pagestermrespiration  denotes the exchange of the respiratory gases (oxygen and carbon dioxide) between the organism and the medium in which it lives and between the cells of the body and the tissue fluid that bathes them. With the exception of energy used by animal  life  in the deep ocean, all energy used by animals is ultimately derived from the energy of  sunlight. The carbon dioxide in the atmosphere in conjunction with the energy of sunlight is used by plants to synthesize sugars and other components. Animals consumeRead MorePrinciples of Natural Selection Under Darwin and Wallace are Variation, Heritability, and Reproduction2343 Words   |  9 Pagesan indispensable mechanism of evolution. First off, to have natural selection, you need diversity among a population such as genetic variation, some species are multi-colored. An example for genetic variation would be the genus delphinidae. Dolphins, pilot whales, and killer whales are all a part of the same family, however they range in colors, shapes, and names making people think they are of a different species when they are all related and have evolved into a large variety.
