Chalicotheres Chalicotheres are not very plentiful in the fossil history and do not show important variations in there body build. This shows that chalicotheres in their history remain important for a particular range of species instead of changing into a variety of different eco types like horses or rhinos had done. Chalicotheres never morphed high-crowned cheek teeth for feeding on grsses or other plants. Maybe this degree of peculiarities in part explains the families decline and ultimatly extinction. Because of their exploration to new habitats the presence of chalicothere remains in a fossil site is a good indicator of an old woodland or forest. Large claws are present on all the toes, the ones on the front legs a larger than the …show more content…
These animals would have ran in a moderately fast pace to withstand the weight and maintain an upright posture the lumbar region is shortened to increase back stregnth. They had shorter necks and much longer arms showing they used there front legs to gather food. there back legs were short but still strong to sit for long periods of time Chalicotheres teeth fell off when the reached a mature age and don't grow back in the front instead they used their hands and tongue to pull food to their mouths. they also had long eyelashes to protect their eyes when eating thick vegetation. Chalicotheres had shorter necks so their arms were there main feeding support Chalicotheres give birth to a single offspring after 10 or so months. Chalicotheres were alive until about 9 million years ago in north america but that is a short time ago considering the cenozoic era is the latest era we are living in. The cenozoic has only lasted 65,000 years to now. the early cenozoic era was much warmer than now and the temperature was the same everywhere regardless of the
On November 16, 2017, Horace Verbermockle was found lifeless as he laid down in the bathroom floor at his house. What happened to Horace Verbermockle?, his wife Minnie Verbermockle claims that Horace must have slipped on soap before she found him unconscious on the floor and alerted the doctor, who stated that Horace was dead when he got there. Minnie was the major suspect in the investigation by the fact that she was the first and only witness of the body. However after reviewing the evidence found at the scene, it is positive that Minnie Verbermockle murdered her husband Horace Verbermockle.
In The United States the number of people in prison is over two million, and of those two million it is estimated that two thirds of them will be back in prison within three years (Correctional Populations). Some people argue that rehabilitation is the most effective way to handle prisoners, but the risks don’t outweigh the benefits, especially for murderers. Nobles was an example of a murderer who appeared rehabilitated, but under close examination of his actions, he was no more than a manipulating sociopath. Nobles was not rehabilitated because his actions in court showed how he felt, his faith was a facade, and he was a schizophrenic.
Danny Clark was an American soldier that fought in a war some time ago. It all began when he need money to live a good life. So he enlisted to the military and he was sent to battle right away.
2. Fossils of its pelvis, legs, and feet indicate that it was bipedal, like humans.
When an evolutionary geologist or paleontologist is lecturing, he/she often uses terms as the Hadean, Achaean, Proterozoic, Paleozoic, Mesozoic, and Cenozoic eras. These are the time periods of the evolutionary timeline. This a major reason showing how the fossil record disproves evolution. The chart above shows the supposed timeline.
Australopithecus afarensis existed between 3.9 and 3.0 million years ago. The distinctive characteristics of A. afarensis were: a low forehead, a bony ridge over the eyes, a flat nose, no chin, more humanlike teeth, pelvis and leg bones resembled those of modern man. Females were smaller than males. Their sexual dimorphism was males:females; 1.5. A. afarensis was not as sexually dimorphic as gorillas, but more sexually dimorphic than humans or chimpanzees. A lot of scientists think that Australopithecus afarensis was partially adapted to climbing the trees, because the fingers and toe bones of the species were curved and longer than the ones of the modern human.
Bipedalism had many advantages, but it also had many disadvantages and provided dangers to early hominids. Some of these disadvantages included i...

The Paleolithic Age was the earliest period of man. This time period dates back to 15,000 BCE. There are many artifacts from the Paleolithic Age including Lucy (female hominid), Otzi (ice man), and cave art.
The time between the formation of the earth and the beginning of the Cambrian(about 570mya) is a 4000 my long period known as the Precambrian, this includes approximately 90% of geological time of which we know very little about as pre-Cambrian rocks are poorly exposed, many have been eroded or metamorphosed and fossils are seldom found.
The increment of time in which humans have existed is a very small portion on the Earth’s evolutionary timescale. It is relatively recent that humans appeared. Our species, Homo sapiens, began evolving about 200,000 years ago (“Early). All life on earth descended from a single living cell. The first life on Earth appeared about 3.5 billion years ago, an estimated 1.3 billion years after the earth was formed. The first living organisms on our planet were simple photosynthetic bacteria. Cells didn’t form until half a billion years later. All life on primitive Earth lived in water, and it wasn’t until 300 million years ago that some life, i.e. human ancestors, left the water and began living on land (“Human).
in the warm climate the men wore long shirts and legging to protect their legs. They also wore breech clothes is a long rectangular piece. The women wore long dresses. In the winter both men and women wore long robes to keep them worm. they also wore a shoe called moccasin which made of animals
-Finally, the pelvic rotation decreases the impact at contact with the running path felt by the runner.
Recorded videos were used to analyze the movement patterns of the runners. The participants were an elite (male) and a novice runner (female). The elite runner used a standard track field while the novice used a treadmill in a standard gym. The result showed that the elite runner had a longer stride than the non-expert due to his long legs. The novice runner required less force to move her body than the elite runner. The expert had longer stride resulting in longer step length which made him move faster than the novice. As the feet of both participants touched the ground the expert had a higher ground reaction force than the non-expert. The elite had a higher cadence than the non-elite because his legs moved faster. During stance phase, they both have one foot on the ground and as their foot first hit the ground they both slow down. However, the novice was slower because the elite had a faster speed making him spend less time in the
1.9 million years ago, Homo Habilis of East Africa had evolved into an entirely new species known as Homo erectus. Homo erectus directly translates to "Upright man" and for good reason. One of largest anatomical advancements of Homo erectus was their arm and leg bones which were very similar in shape and proportions to that of modern day humans. "Their legs would have made Homo erectus efficient long distance runners like modern humans."(Dennis). Along with their longer more developed legs, Homo erectus's leg were also hairless which allowed them to evaporate sweat and thus be more efficient at not overheating. This advantage allowed Homo erectus to chase down four legged mammals to the point of heat exhaustion and thus drastically increase the efficiency their hunting tactics. Another change in the legs of Homo erectus was their slightly more narrow pelvises. This forced the size of a child’s head to be smaller at birth and undergo most of its development during childhood.
