Evidence for Evolution Activity
Fossil Record
The most ancient common ancestor, or “stem” species, from which later on in time hominids originated was the Australopithecus afarensis species, which were Lucy and other members of her species. They lived somewhere between 3.9 and 3.0 million years ago.
Five species that are from the Homo genus are Homo habilis, Homo erectus, Homo heidelbergensis, Homo neanderthalensis, and Homo sapiens.
One extinction that occurred was at end Permian, at the end of the Paleozoic era which wiped out about 90% of all species which may be caused by volcanism, meteor, global warming, sea-level changes, glaciation, or ocean chemistry changes. Another extinction that occurred was at end Cretaceous, at the

As the fossil chordates, horses evolved the spine evolved from an arc to a straight spine, the neck became more upright like a modern horse, and the structure of the front legs became more straight rather than curved which makes the horse have a better posture and stand up straight with a straight spine. There are adaptive values of various structural changes that have occurred through horse evolution like the front and back legs became more straight to make it run more efficiently. Also the spine became more straight rather than an arc to make the horse be more stable and balanced so the horse can run efficiently. The significance of the Cambrian explosion was that most of the major animals were formed during the Cambrian Period and have been evolving since …show more content…
Also, between species that inhabit similar environments is persuasive evidence of the evolutionary origin of biodiversity. The world’s oceans have never been frozen from one north to the south, polar bears could have reached the Antarctic but they are not strong enough to swim there, even though they are strong swimmers. Also there are would be no penguins in the Arctic because penguins are a key prey for polar bears which, if there were in the Arctic, kill all of the penguins in the
Riversleigh Fossil Site, Australia Geological History Riversleigh covers an area of approximately 80 square kilometres and is located 250 km north-west of Mt Isa. Riversleigh is Australia’s most famous fossil site and fossils were first discovered in the area in 1901. The fossils document the evolution and changes of Australia's terrestrial fauna and ecosystems.
Article Review #3 The article “Ardipithecus ramidus: A New Kind of Ancestor: Ardipithecus Unveiled” written by Anna Gibbons, talks about how scientist learn many things about human evolution through artifacts of ancestors, DNA and bones. All of this helps reveals different things about our past and how we came to be. This article briefly mentions Lucy and it mainly focuses on the discovery of ardipithecus ramidus.
Therefore, through the addition of further survival pressures, humans changed the local ecosystem, inevitably subjecting megafauna species on the verge of extinction to their demise. Moreover, Martin demonstrates the responsibility of human activity in the extinction of species through the comparison of the relative megafauna age extinctions between
The Piltdown fossils man was the missing link between apes and humans found in 1911 and 1912. The fossils included a portion of the skull, a jawbone and a few teeth. The relics were said to be found in Piltdown, England by workers digging a pit. The scientist discovered that the jaw and teeth were not the same age as the skull and were not even fossils, just old
As my team and I discovered a new fossil in our excavation project, the unknown site yielded the skull of a mysterious specimen. Our goal as reputable anthropologist was to analyze the specimen to the best of our ability so our team can provide the most probable and reliable taxonomic identification. In order for us to effectively interpret the results our experiment yielded, we needed to review our knowledge in human evolution. The field that uncovers the mystery of the evolution of humans is paleoanthropology, the study of human evolution through the fossil record.
climate change influenced nonhuman primate evolution because with the changes, nonhuman primates were forced to evolve in order to survive. As the climate change progressed and several species started to die out, nonhuman primates evolved through time and thus they were able to survive and climate change that occurred and were able to evolve into creatures that we see during present times. The theories of early primate evolution appeared about 60 million years ago after most of the early living species had already become extinct. New discoveries have supported one theory over another as more research is done.
Richard W. Wrangham is a Professor of Biological Anthropology at Harvard University. He had a long term study in Kanyawara chimpanzees and he was well known for his work in the ecology of primate social system. The book Catching Fire refers to the activities of our human ancestors when they began to use fire to practice cooked diet. Although the topic is pretty academic, but Richard used simple sentences and words to explain his ideas well. Yet the proof is still preciseness with provided evidences, and the conclusion is convincible.
The name of my book is The Ghost of Fossil Glen by Cynthia Defelice it was published on March 25, 1998. Cynthia Defelice wrote the book because as a child her mother read to her and that’s when she started loving books but it wasn't until she was 36 that she decided she wanted books for children. Other than being a writer she also owns a farm with her husband who is retired and she want to improve her farm. Defelice has written 16 novel and 12 picture books for young readers three of her books are The Ghost of Cutler Creek,Fort, and Wild Life. In the beginning of the story the setting is on a cliff in Fossil Glen and moves on to her school and her home.
Due to the aforementioned factors, we are tempted to see the species of today as a monument of the theory of evolution, but it actually undercuts the facts of evolution. Furthermore, a number of misconceptions have erupted throughout the years for the sole reason of not having an appropriate explanation for the facts of the theory of evolution. We are forced to accept wrong notions for us to be able to fully understand the said
The Pleistocene epoch, which occurred around 2.6 million years ago and lasted until about 11,700 years ago, was a time of severe global warming and global cooling. This period of time is known to have marked the most recent documented Ice Age. Of the five cited Ice Ages that have occurred since the beginning of time, The Pleistocene Epoch was the first to accrue humans. Moreover, the animals inhabiting the Earth throughout this era were predominately larger than animals living today. Given the facts, many have claimed that the animals existing in the time of the Pleistocene Epoch were genetic ancestors of the animals living in our present day; however, it can be more accurately presumed that it was within the Pleistocene Epoch that the evolution
Introduction The theory of evolution has been discussed, evaluated, and researched many times since the theory was first brought to light. Darwin’s theory of evolution is said to be divided into two parts, common decent and natural selection (Bouzat, 2014). Many research papers agreeing with Darwin’s theory comment on the diversity of a species and how they have descended from one common ancestor. Natural selection is a process in which species that are better adapted to the environment tend to survive and reproduce (Dictonary.com).
The Earth's climate went through several major changes throughout the Tertiary period that led to the flourishing of primate species and the extinction of other primate species. The plesiadaptiforms, which are not considered real primates because of the lack of key primate features, went extinct at the end of the Paleocene epoch. At the beginning of the Eocene epoch came the euprimates, considered the first real primates, whose features made them well-adapted to arboreal life. Euprimates had convergent eye orbits, opposable digits, nails, and larger brains than plesiadaptiforms. This coincides with a period of global warming which made for a more tropical and forested habitat.
xplain how each of the following provide evidence supporting evolution. Provide at least one specific example of each. a. Transitional fossils: Transitional fossils are the missing links between animals we see today and their ancestors. During evolution, many animals developed adaptations and evolved over time to be better suited for life on Earth. An example of a transitional fossil is Pakicetus, which is an early ancestor to today’s whales.
And shows that animals indeed did evolve from lager extinct animals. The voyage as so important to the development of his theory because it shows that fossils were evidence of evolutionary
Fossils of the Equidae family are very widespread and described as a very widespread group during the time period of the Pliocene (Kalmykov, 2015). The Eocene period lasted approximately from 56 million years ago to 34 million years ago. These early “horses” did not have the same anatomical hoof structure that today’s Equids have, they had 3 toes on their front feet and 4 toes on their back feet. Over time, the side toes were lost and the middle toe came to be a single hoof.
