What is Evolution? It “is the process by which modern organisms have descended from ancient ancestors” [1]. Many great scientists have developed theories to answer the question, “Where did life, and human beings, come from?” Two major theories of evolution that still exist, and valid today are Charles Darwin’s theory, and Lamarck’s theory. These two theories have many differences, but attempt to explain evolution. Charles Robert Darwin, was a naturalist, who proposed one of the most renowned theories
percent of all species are extinct, though this is over 3.5 billion years at low rates, since the evolution of Homo Sapiens, specifically the last 20,000 years, the extinction rates have increased by 1000 ( back ground rate and http://www.endangeredspeciesinternational.org/overview.html). Habitat destruction, overexploitation, pollution and the introduction of invasive species are major anthropogenic causes of biodiversity loss within species, ultimately resulting in the decline of species (Sharma et
The human species have been able to overcome many obstacles. The key to man’s success is based off its ability to adapt. These instincts helped them to survive the perilous ice age. Homo Sapiens learned how to change and adjust to severe climates. Man’s mobility and adaptability were the two features that kept the early man alive. Many people say, “The fact that these early hominids survived at all was a miracle”. Within these hospitable conditions, it was their ultimate survival weapon to preserve
most of the species (both flora and fauna) are under serious threat from direct and indirect human activities; while the direct activities such as deforestation leads to species habitat fragmentation and loss, on the other hand modifies climatic conditions coupled with gas emissions. The synergistic impact of these human driven activities questions the survivability of organisms in the morphed climatic environments. At one level fragmented habitats increase intra and inter species competitions,
The Theory of Evolution: “Grievously Hypothetical” *Rough Draft* First Publicized in Charles Darwin’s On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, The Theory of Evolution has been a widely excepted theory all around the world. According to the Pew Research Center, approximately 60% of all American adults believe in Darwinian evolution (Public 's Views on Human Evolution). This is an absurdly large amount of the United States’
complex as the Bonobo, certain species have changed to the point where they cannot be seen as related to their ancestors at all. The Bonobo (Pan paniscus), the Emu (Dromaius novaehollandiae), the domestic Dog (Canis lupus familiaris), the Rhinoceros (Rhinocerotidae), Blue Whale (Balaenoptera musculus), Lion(Panthera leo), and American Crocodile (Crocodylus acutus) are all prime examples of organisms that are all related to one common ancestor. Of this group of species, Blue Whale (Balaenoptera musculus)
Introduction This paper will explore the theory of evolution and its main contributing species. The Australopithecus is the most primitive common ancestor between humans and apes. Though its contributions to evolution were few, it was still a vital part in evolution being the first ape-like creatures to be known as related to modern humans. Homo sapiens are the first species that share a genus with modern humans. They are slightly more advanced than Australopithecines. Homo erectus are one of the
great progress in discovering all of the different kinds of human species. The discovery of a certain early human species, Australopithecus afarensis was initially credited to the finding of a single individual, AL 288-1, or “Lucy.” She has helped anthropologists to understand the diet, anatomy, environment, sexual dimorphism, the technology or tools used during their time, and bipedalism of this early hominin species. The evolution of humans is interesting due to the questions we are trying to find
The species Homo neandertalensis has been a subject to much debate over history. This species was once thought as one of us. The existent of this species has undergone conversions about their importance and their evolutionary situation. Moreover, the biggest question we ask is what happened to the Neanderthals? Two debates concerning what happened to the Neanderthals have been continuing since the 19th century. One side of the debate believes that they were unable to compete with modern humans or
Evolution is reoccuring, the world changes little by little, day by day. Evolution is the mere evidence of changes in the environment and the organisms inhabiting it. It is the biology in earth’s history. The measurement of evolution varies on each organism. Some organisms evolve at a faster rate and some gradually change depending on their fitness rate to be able to survive varying environments and timelines. One example of evolution in species today is the mustard plant “ Arabidopsis Thaliana”
