Annotated Bibliography: Hominins
Set 3: Hominins. Appropriate topics include (but are not limited to) finds of new fossils early human ancestors, or any analysis of earlier finds.
Inappropriate topics include dinosaurs, Big Foot sightings, Noah’s Ark, etc.
Please note that the current trend is for researchers to use “hominid” to refer to African apes (this usage would include chimpanzees, bonobos, and gorillas as well as humans), and “hominin” to refer to human ancestors (those that follow the divergence of the human and chimpanzee lines).
Some older articles may use “hominid” to refer to the fossil bipedal forms. What’s important is that the articles focus on fossil human ancestors, not whether the article uses “hominin” or “hominid”.

98 million years old. Those finding might have been settled right after scientists figured out the date of those early human fossils, Australopithecus sediba, in which discovered in South Africa by a year ago. The whole succession of the investigations covered all the new cave sediments, in which stored all the fossils and has been discovered by the scientist to identify the age. A bunch of papers distributed an article about the exact age for the fossils, and more ideas for the investigation of other body’s parts. Researchers think understanding the fossils age can led scientists to think in a different perspective, in order to demonstrate the inheritance marina, and the precise age can help us to found out the most suitable, significant person in human ancestor. Scientist also emphasis that the outcome of the whole investigations can also be the reference for trying to figure the accurate date in early human fossils. They think the date can know the fossils were saved in the Malapa throughout the period of thousand years, the time around 1. 98 million time, since the Earth's magnetic field flipped 180 degrees in order to back …show more content…
Scientists published the research of understanding the humans origins and got attention from all different countries, by giving them advice about early human ancestor can possibly live with a various of woodland community habitually eats included the food which is hard to chew like leaves and trees. In the other investigation from another scientist said Australopithecus sediba didn’t have a good structure for the mouth to eat in order to have a unfaltering diet of eating hard sustenance. However, a new research doesn't straightforwardly locate if Australopithecus sediba really has a close relative of early Homo for evolution, anyway it still does furnish better proof that the dietary progressions has formed those important and essential evolutionary for the humans nowadays. Researchers think that their investigation gives a truly corroboration of the contrast between rebuilding the animals who almost extincted and knowing those modification. The analysis of A. Sediba’s teeth gave scientist a big surprise to know two groups of different type must had been eaten hard substance like tree and leave before they disappear in this world. This gave scientist a sign of their diet and behavior.
In the exhibit for The Humans Outside of Africa, there were different skull fossils that were studied and categorized as potentially male or female. However, it is also notable that there were fossils (D2700 and D2735) that were examined to be that of an adolescent. Therefore, this provides paleoanthropologists with a basis for studying the Dmanisi hominids on a generational basis, from adolescent to old
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.
For humans, the tooth shape reflects based on how we consume in our diet quality. The majority of humans in today’s generation consume meat, which molds our molars to be a lot smaller opposed to the other primates. The diet quality of fossil hominins is relevant to the shape of their tooth, in which certain kinds of their species that have consumed fruits
With a larger brain, they were able to make better decisions when it came to searching for food. Around 1.5 million years ago, a new variation of the hominid emerged. They were named Homo erectus and were able to make more sophisticated tools. They were the first hominids to leave Africa and travel to parts of Europe and Asia.
From the fossil teeth, we can infer that insects were not the only food for early primates, they also eat fruits as there are the presence of round molars which facilitate grinding. For instance, from the features of lions, we can see that they eat both meats and plats. In their teeth, there are both flat sharp molars. The flatter and rounder molars are for grinding grass fruits while sharper molars are for tearing meats. Also, by observing human fossil teeth, the flat and round molars enable them to grind plants and fruits.
We measured the skulls of the fossil hominins: Australopithecus, Homo habilis, Homo erectus, and Neanderthal. We measured the length, height, width and orbit height of their skulls to calculate the estimated brain size and estimated body mass. Hypothesis 1. For Life History, humans will reproduce earlier than the primates and apes because of their body mass.
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
Hominin Split: They were the first primates that left the trees and stood up in grassland approximately 7 to 6 million years ago. They were called spilt because this separates hominins which are basically any primates that stands at least part time from other primates like Chimpanzees, apes, Gorillas and etc. They were historically important because they were the first primates to stand up in grass land so that they can hunt and survive their life more easily comparing to other primates who didn’t stand up and which gives us idea about that from them evolution of modern man have started gradually.
The physical nature of a primate body as wells as its movement is a unique factor in the animal kingdom. There has been continuous change through locomotion and body configuration throughout each grades of primate evolution. In this essay I will be discussing the modifications in time as well as theories in each grade of primate. This research paper will try to elaborate on the evolutionary modifications and some of the theories that have been proposed for these changes throughout our and other primate evolution. With time primates development was due to environmental changes.
With research done to fossils and skeletons of possible primates from the past with comparison to primates of the present shows
This discovery proved that this fossil was the bipedal middle between an ape and human. Chapter 5– Questions 1-4 Roy was explorative, and passionate about nature at a young age. He loved to fish, hunt and camp, and had his heart set on being a naturalist and explorer. These characteristics made him perfectly capable to be a skilled explorer. Roy's exploration consisted of reconstructing the plateau of Central Asia (geology, vegetation, past climate, and fossils).
Deborah Swarthout Modern Man and Neanderthals WCCCD-Fall 2017 Modern Man and Neanderthals: Where did they go? It has long been thought that modern man evolved from the Neanderthals. Although we have many similarities, the most recent studies suggest that modern man actually co-existed alongside the Neanderthals and interbred with them to create the modern man we know today. Neanderthals or Neandertals (Homo Neanderthalensis) are considered to be our closest extinct human relatives.
Critical thinking questions: physical anthropology textbook 1. Given that you’ve only just been introduced to the field of physical anthropology, why do you think subjects such as skeletal anatomy, genetics, nonhuman primate behavior, and human evolution are integrated into a discussion of what it means to be human? The study of physical anthropology integrates the subjects of skeletal anatomy, genetics, nonhuman primate behavior, and human evolution because anthropologists look to the fossilized remains of hominins to see what their environments were like and what they ate. In addition to these sub fields, anthropologists look to skeletal anatomy to see any evolutionary change or if the hominin had died from any diseases and how old and tall
Your Inner Fish In the book Your Inner Fish by Neil Shubin, Dr. Shubin, a 55-year old paleontologist, explains how every living organism can somehow be drawn back to a common ancestor, and that we are all theoretically related. Shubin explains in depth about the “Journey Into the 3.5-Billion-Year History of the Human Body,” and how we are all intertwined and connected back to the very first living organisms. Dr. Shubin bases a lot of the book on things he has found while looking for fossils, and things he had studied while in college, naming many different scientists and how they helped him to put together facts and puzzle pieces to write this book. You find that Doctor Shubin always relates his topics back to his personal story of expeditions
BIOLOGY RESEARCH ESSAY There is great speculation around evolution. As we are continually in the process of discovering the history of human beings, there are many questions surrounding this topic. One very interesting question is why ancient ancestors of homo-sapiens evolved to walk upright like we do today. An apes’ DNA is astonishingly similar to that of a humans, (97% the same) and yet, our bones’ shapes and structure are very different.
