Full Answer
More specifically, an ape is defined as a primate that does not have a tail and includes the gibbon family (Hylobatidae) and the Hominidae families (i.e. humans, chimpanzees, orangutans, gorillas, and bonobos). So, from an evolutionary standpoint, how are we related to the other apes? Unfortunately this answer is not clear.
Still, Huxley’s work made it starkly clear that humans were a Great Ape, closer to our African kin than our East Asian ape cousins, the orangutan.
It was unclear, however, which of the hundreds of extinct ape species found during the nineteenth and twentieth centuries in Africa, Europe and Asia, dating from the period 10 million to 35 million years old, gave rise to the human lineage. By the mid-1960s this seemed to be solved.
It was even suggested that humans had split from a common ancestor with the African apes by about 30 million years ago, making our evolution a very long process indeed.
about 4 million to 6 million years agoFor the past 45 years, geneticists have suggested that the ancestors of today's humans and chimps went their separate ways about 4 million to 6 million years ago, and the ancestors of gorillas diverged about 7 million to 9 million years ago.
25 million to 30 million years agoMolecular clocks suggest that Old World monkeys and apes split from their common ancestor 25 million to 30 million years ago.
Overall, they calculate that the human and chimp lines must have split finally apart at the earliest 6.3 million years ago and more probably 5.4 million years ago, a sharp discrepancy with the Sahelanthropus date.
about five to seven million years agoEvidence from fossils, proteins and genetic studies indicates that humans and chimpanzees had a common ancestor millions of years ago. Most scientists believe that the 'human' family tree (known as the sub-group hominin) split from the chimpanzees and other apes about five to seven million years ago.
Humans and monkeys are both primates. But humans are not descended from monkeys or any other primate living today. We do share a common ape ancestor with chimpanzees. It lived between 8 and 6 million years ago.
While humans lack the sheer power of the mighty chimp, our nervous systems exert much more control over our muscles, enabling us to execute far more subtle movements. Humans possess superior motor control, less body hair and a far more advanced brain.
Perhaps we will have longer arms and legs. In a colder, Ice-Age type climate, could we even become even chubbier, with insulating body hair, like our Neanderthal relatives? We don't know, but, certainly, human genetic variation is increasing.
Modern chimps have been around for longer than modern humans have (less than 1 million years compared to 300,000 for Homo sapiens, according to the most recent estimates), but we've been on separate evolutionary paths for 6 million or 7 million years.
about 3.9 billion years agoThe most recent common ancestor of all currently living organisms is the last universal ancestor, which lived about 3.9 billion years ago.
There's a simple answer: Humans did not evolve from chimpanzees or any of the other great apes that live today. We instead share a common ancestor that lived roughly 10 million years ago.
The chimpanzee–human last common ancestor (CHLCA) is the last common ancestor shared by the extant Homo (human) and Pan (chimpanzee and bonobo) genera of Hominini.
Humans are one type of several living species of great apes. Humans evolved alongside orangutans, chimpanzees, bonobos, and gorillas. All of these share a common ancestor before about 7 million years ago.
Controversial Study Claims Apes and Human Ancestors Split in Southern Europe. Researchers believe these 7.2-million-year-old teeth have a lot to say about human evolution
Scientists carefully study fossils to determine what the last common ancestor of humans and African apes looked like. This image shows Paranthropus boisei, a hominid that lived in sub-Saharan ...
Dating Slavic, Russian, and Ukrainian women in a multicultural and international environment that we share today is far from a mail order brides operation, but is an open and transparent experience of people from different locations connecting and sharing their ideas, thoughts, common goals and aspirations, without prejudice or borders.
The Little Foot fossil proved to be the best evidence of how human ancestors used their arms more than 3 million years ago as the shoulder components were clearly apelike.
The Little Foot fossil is a rare specimen because it is a near-complete skeleton of an Australopithecus individual much older than most other human ancestors. The creature was called “Little Foot” because the first bones discovered by scientists consisted of a few small foot bones.
A clue to interpreting the human evolutionary tree. Scientists at the Keck School of Medicine of USC examined the upper body of the famed fossil “Little Foot”, and may have found confirmation of how our human ancestors used their arms, Science Daily reported.
The careful and detailed dissections of Great Apes and humans done by ‘Darwin’s bulldog’, T.H. Huxley, in the late nineteenth century seemed to reveal that gorillas and chimpanzees were physically more alike than either species was to humans.
Most molecular clocks at the time, and many since, put the split between humans and chimpanzees at only around 5-6 million years ago. But now the fossil record had pushed the date back, and so the molecular clocks would need to be rethought.
These first molecular clocks suggested humans and gorillas had separated only around 11 million years ago , not 30 million as suggested by fossils like Ramapithecus.
Another fossil probably belonging to the gorilla branch is Nakalipithecus from Kenya, found also in 2007, but dated to about 10 million years old. These fossils together constrain the age of the gorilla versus chimpanzee-human split to between 8 and 10 million years ago, well within the range of estimates from molecular clocks.
So far, we’ve found just three fossil teeth for the entirety of chimpanzee evolution, and they’re a mere 500,000 years old. As I noted earlier, Huxley’s dissections in the late 1800s established the closeness of humans to chimpanzees and gorillas. But, for a good portion of the twentieth century, the precise branching arrangements ...
Still, truth is we have so few fossils in the window of 4 million to 12 million years ago that we’re a long way from having a clear sense of when and how gorillas, ...
Coincidentally, at the time Ramapithecus was being touted as the first human ancestor, pioneers of the nascent field of molecular biology were beginning to compare blood proteins among different mammals, including humans and apes, to study their evolution.
Choo choo! Onto the next: Australopithecus, or southern ape, named in reference to where the first fossils were found (southern Africa). This genus lived in African 4 million to 2 million years ago. What do we know about this genus? Well...
Take a look at an ape. It's hairy. It swings from trees. And its teeth look pretty intimidating. You probably think you don't have much in common with these long armed, wild creatures, but you do! In fact the term 'ape' even includes humans. More specifically, an ape is defined as a primate that does not have a tail and includes the gibbon family (Hylobatidae) and the Hominidae families (i.e. humans, chimpanzees, orangutans, gorillas, and bonobos).
Our first stop on the human evolution train belongs to the genus Dryopithecus, which means tree ape. A genus is a classification system that is broader than species, but less broad than family. Many of the apes went extinct when the climate cooled, which resulted in the disappearance of tropical regions. Dryopithecus survived the climatic change and is thought to have migrated to Africa to find a suitable habitat.
This is the last stop before we reach present day humans. Homo neanderthalensis lived 400,000 to 40,000 years ago in Europe and Asia. Their name is based on where the first fossil was found (Neander Valley in Germany).
