10 Transitional Ancestors of Human Evolution

10 Transitional Ancestors of Human Evolution
Humans The evolution from our closest non-human ancestor to present day humans is one with many transitions. Some of these transitions are widely agreed upon by the scientific community while others are shrouded in frustrating darkness. Below are the ten species that have added the most to our lineage, some adding seemingly simple advances like walking on two legs and chewing food differently to mastering fire and dominating every other species on Earth. Sahelanthropus tchadensis 6-7 mya The beginnings of our lineage away from the Great Apes really start with the separation from chimpanzees, our closest non-hominin relative. Kenyanthropus platyops 3.5 mya Found at Lake Turkana, Kenya in 1999, K. platyops changed the way paleoanthropologists viewed our ancestral tree. Australopithecus afarensis 3.0-3.9 mya In 1974 at Hadar, Ethiopia researchers discovered about 40% of a skeleton came to be known as “Lucy.” Paranthropus boisei 1.4-2.3 mya Homo habilis 1.6-2.5 mya Homo ergaster 1.5-1.8 mya Homo erectus

Knowledge Doubling Every 12 Months, Soon to be Every 12 Hours Knowledge Doubling Curve Buckminster Fuller created the “Knowledge Doubling Curve”; he noticed that until 1900 human knowledge doubled approximately every century. By the end of World War II knowledge was doubling every 25 years. Today things are not as simple as different types of knowledge have different rates of growth. For example, nanotechnology knowledge is doubling every two years and clinical knowledge every 18 months.

10 fascinating facts about woolly mammoths Sequencing an extinct genome is no longer a pipe dream, says evolutionary biologist and ancient DNA specialist Hendrik Poinar in today’s talk. It’s a modern reality, and we’re not too far from seeing a revived extinct species walking the Earth again — maybe even a woolly mammoth. In this talk from TEDxDeExtinction, Poinar talks about how he and fellow scientists are getting closer to completing a woolly mammoth genome, an intricate puzzle that consists of discovering, entangling and connecting over 5 billion base pairs. Hendrik Poinar: Bring back the woolly mammoth! So, why do we, humans, have such a fascination with woolly mammoths?

Timeline of human evolution Haeckel's Paleontological Tree of Vertebrates (c. 1879). The evolutionary history of species has been described as a "tree" with many branches arising from a single trunk. While Haeckel's tree is somewhat outdated, it illustrates clearly the principles that more complex modern reconstructions can obscure. The timeline of human evolution outlines the major events in the development of the human species, Homo sapiens, and the evolution of human ancestors. It includes brief explanations of some of the species, genera, and the higher ranks of taxa that are seen today as possible ancestors of modern humans. A caution: Other than Mr Haeckel's historic and emblematic "tree", this article provides no phylogenetics analysis to help portray the complex, nonlinear facts of human evolution.

Scientists Discover Blood inside 15,000 ya Mammoth Russian scientists claimed Wednesday they have discovered blood in the carcass of a woolly mammoth, adding that the rare find could boost their chances of cloning the prehistoric animal. An expedition led by Russian scientists earlier this month uncovered the well-preserved carcass of a female mammoth on a remote island in the Arctic Ocean. Semyon Grigoryev, the head of the expedition, said the animal died at the age of around 60 some 10,000 to 15,000 years ago, and that it was the first time that an old female had been found. But what was more surprising was that the carcass was so well preserved that it still had blood and muscle tissue. "When we broke the ice beneath her stomach, the blood flowed out from there, it was very dark," Grigoryev, who is a scientist at the Yakutsk-based Northeastern Federal University, told AFP. "This is the most astonishing case in my entire life.

Annenberg Media Exhibits: Collapse Hundreds of years ago in what is now modern Honduras, Copán was a thriving civilization, a center of the cultural life of the Maya. Tens of thousands of people made their home in the Copán Valley. Yet despite its importance, Copán went into decline. Across the vast territory of the ancient Maya, other important sites were sharing a similar fate. Classic Maya civilization was collapsing.

Extinct Giant Whale-Eating Whale Found - Unlike modern sperm whales, this one had teeth in both jaws and might have eaten like killer whales. - The 10-foot sperm whale skull fossil is the largest ever found. - Its main food might have been baleen whales. The massive skull and jaw of a 13-million-year-old sperm whale has been discovered eroding from the windblown sands of a coastal desert of Peru.

China's Challenges NETA Feed Info: 5/60s - Saturdays, beginning October 5, 2013 @ 1630-1730ET/HD04. NOLA code CHIN 0100 H1 China has new leaders. "The Chinese Dream," says China's new president, Xi Jinping, is "the great rejuvenation of the Chinese nation." China is an economic superpower: the largest population on earth is undergoing the greatest transformation in history and competing in every arena of human endeavor. China's growing strengths have global import. Multituberculata The Multituberculata were a group of rodent-like mammals that existed for approximately one hundred and twenty million years—the longest fossil history of any mammal lineage—but were eventually outcompeted by rodents, becoming extinct during the early Oligocene.[1] At least 200 species are known, ranging from mouse-sized to beaver-sized. These species occupied a diversity of ecological niches, ranging from burrow-dwelling to squirrel-like arborealism.[2] Multituberculates are usually placed outside either of the two main groups of living mammals—Theria, including placentals and marsupials, and Monotremata[3]—but closer to Theria than to monotremes.[4][5] History[edit] Geographic distribution[edit] Multituberculates are mostly known from the northern continents (Laurasia), but there are some records, many of which are controversial, from the southern continents (Gondwana).

Magna Carta: Cornerstone of the U.S. Constitution At the death of his brother, Richard the Lionhearted, John assumed the throne of England, intent on exercising power to achieve his own selfish ends. To fund military campaigns in France, he extracted exorbitant fees from nobles, who, in turn, raised the rents imposed on their tenants. At the same time, John reduced the lords' customary powers over those tenants, restricting, for example, their power to hold court for those living on their feudal lands. Human Evolution Evidence Scientists have discovered a wealth of evidence concerning human evolution, and this evidence comes in many forms. Thousands of human fossils enable researchers and students to study the changes that occurred in brain and body size, locomotion, diet, and other aspects regarding the way of life of early human species over the past 6 million years. Millions of stone tools, figurines and paintings, footprints, and other traces of human behavior in the prehistoric record tell about where and how early humans lived and when certain technological innovations were invented.
