Evolution Of The Fossil Record - 900 Words

Through the fossil record, scientists have been able to observe the changes among different homo genus, as they evolved over time becoming what we now know as the modern human (Fossil Record, 2015). The fossil record not only organizes the sequential generations that have changed over time to adapt better to their environments, but it also provides a time line to how homo sapiens came to exist (Fossil Record, 2015). Through careful analysis of the human fossil record, characteristics in the skull such as the brow ridge, brain size, cranial capacity, dentition, nasal cavity, eye sockets, mandible, and the cranial base are all characterizes, that both connect the three specimens Homo erectus, Neanderthals, and modern human, as well as, set them apart. Homo erectus being the oldest of the three skulls dates back up to 1.8 million years ago to 300 ka yBP. This genus was known for its large brow ridges, used to support the muscles of its massive jaw (Fagan, 1994). Also, Homo erectus had low and elongated skulls, bigger brains flatter faces, smaller molars and thinner enamels, although they did still contain large nasal cavities and rounded eye sockets compared to that of other archaic homo genus (Larsen, 2014). In addition, Homo erectus also contained a thick walled, rounded skull, a sloping forehead, and had a cranial capacity ranging from 8 hundred to 13 thousand (Fagan, 1994), and a cranial base, which is the delicate bony platform behind the eyes on which the brain rests,Show MoreRelatedEvolution Vs. Fossil Records912 Words   |  4 PagesEvolution has been a widely known discussion that many people have had over the past century, the theory of evolution has been welcomed by many scientists yet by some religious people it has b een a taboo topic. The thought or the motion to entertain that humans evolved from primates is what some people would shudder and state that it goes against all their religious beliefs. However, scientist have pushed on the fact that evolution is not just a hypothetical or an outlandish theory but a theoryRead MoreUsing Fossil Records to Compare Evolution and Creationism807 Words   |  3 PagesFossil Records: Evolution vs. Creation Defined in Biology, evolution is as a change in allele frequencies of a population. To more simply express, a change in the genetic coding (DNA) of a group of organisms. These changes can be as simple as eye or hair color, and as complex has the development of limb and finger bones as seen in evolution of fish to land-roaming tetrapods (Tiktaalik roseae). A strong factor supporting evolution is the history of life as documented by fossils, known as the fossilRead MoreIn The Article The Fossil Record Supports Evolution, Writer,938 Words   |  4 Pages In the article The Fossil Record Supports Evolution, writer, David A. Thomas argues his position. He favors Evolution over Creationism. In the article David explains how there are gaps in fossilization. He tells how creationists expose those gaps and claim that because of those gaps evolution is not proven to be true. However Thomas explains that there are many difficult steps in the process of uncovering fossils, but those difficult ies don’t disprove anything. He says that creationists say thatRead MoreEvidence of Evolution in Fossil Records and the Process of Spontaneous Origins of Life728 Words   |  3 PagesThe fossil record can show evidence for evolution, by relative dating, and radioactive dating we can find evidence for evolution. Relative dating is the process of finding out the age of a fossil by comparing it to other fossils/rocks. This process helps us determine how old certain specific fossils are by comparing them to other fossils; comparing older ancestor fossils helps us see the physical evolutionary change as time goes on, index fossils are used to determine the age of the fossil. RadioactiveRead MoreEvolution And Evolution Of Evolution1054 Words   |  5 Pages Evolution is something that can be taken into different meanings, from the way you live. Some people can accept evolution and some can’t. The meaning of evolution is the way a different animal or species came to be, and how they are linked to a different of species that all share a common ancestor (an introduction to evolution). There is a lot of evidence to shows that evolution is can be proven like DNA Sequences, Fossil Records, Cladograms, and analogous/homologous structures, because there areRead MoreEvolution Of Life On Earth1667 Words   |  7 PagesFossils can provide us with a great deal of information about the past. They can also help us to understand the present. When do we believe life on earth originated? The earth cooled from its formation 4.6 billion years ago. Life on earth began 3.5 billion years ago, evidence supporting this statement is that the earliest fossils were found from up to 3.5 billion years ago. The following steps are believed to be the major stages in the evolution of life on Earth: 1. The formation of organic moleculesRead MoreEvolution Is More Correct Than Creationism1196 Words   |  5 PagesWhy Evolution is More Correct than Creationism Would you believe that humans and other primates have a common ancestor? Would you believe that you evolved so much that your appendix is a useless organ? Evolution has all of the answers to these questions. However, Creationism doesn’t have all of the answers. Over 60 percent of people believe in evolution. Why shouldn’t you? Evolution is defined as â€Å"the slow process by which changes in plants and animals happen over time† (Webster’s Dictionary)Read MoreSimilarities Between Humans And Humans1067 Words   |  5 Pagesthe theory of evolution. The theory of evolution brought many interpretation from scientists and people. But can you considered the theory of evolution, a fact or fiction? In my opinion, the theory of evolution is considered a fact, supported by the changes in species, common ancestry, and is evident in today’s modern life. To understand the debatable topic of evolution, the theory of evolution must be incorporated. Charles Darwin who was a naturalist, created the theory of evolution by natural selectionRead MoreA Fossil Lagerstatten Is A Form Of Sedimentary Deposits1410 Words   |  6 PagesA fossil Lagerstà ¤tten is a form of sedimentary deposit that is of high value due to the fossils that it contains (Clarkson, 1998). The geological horizons containing these deposits were named by the German Palaeontologist Adolf Seilacher in 1985 (Nudds Seldon, 2008), ‘Lager’ meaning Stratum and ‘Stà ¤tte’ meaning place (Allaby, 2013). Palaeontologists divide fossil Lagerstà ¤tten into two types; Konservant-Lagerstà ¤tten (Nudds Seldon, 2008), or conservation deposits, are horizons that show exceptionalRead MoreHuman Evolution Myth or Fact1313 Words   |  6 PagesThe debate of human evolution being fact or fiction has been around for hundreds of years. Evidence of human ancestry has been found in many parts of the world and these fossils found have been proven to be human. The parts of the world include Eurasia and Africa. Although fossils are found in Eurasia, the human ancestor the Hominoidea has been traced back to the Miocene epochs, which were 23 to 5 million years ago. The Hominoidea is a super-family, which contains many species that are existent today
