In a new book, documentary, and promotional Web site, paleontologist Jorn Hurum, who led the team that analyzed the 47-million-year-old fossil seen above, suggests Ida is a critical missinglink species in primate evolution. The fossil, he says, bridges the evolutionary split between higher primates such as monkeys, apes, and humans and their more distant relatives such as lemurs. "This is the first link to all humans," Hurum, of the Natural History Museum in Oslo,
Norway, said in a statement. Ida represents "the closest thing we can get to a direct ancestor."

Five Principles of Evolution
Variation has a genetic origin due to mutation and recombination
Natural selection and gene flow causes changes in gene frequency in populations
Adaptation is genetically based and leads to changes in population over time
Species formation evolves through reproductive isolation
Genetic changes through natural selection lead to new species

In 2004 a group of scientists found the partial skeleton of a new human species we had never seen before. Researchers called the remains LB1, also nicknamed the hobbit due to its small size. It was first believed that this new species, Homo floresiensis, was a descendent of Homo erectus that had simply dwarfed over time due to limited access to resources. However, newer studies have highlighted some of the more primitive characteristics of LB1, which lead scientists to believe that the hobbits branched off from the human family tree much earlier than previously thought.…

In 2010, Svante Pääbo and his colleagues presented a draft version of the genome from a small fragment of a human finger bone discovered in Denisova Cave in southern Siberia. The DNA sequences showed that this individual came from a previously unknown group of extinct humans that have become known as Denisovans. Together with their sister group the Neandertals, Denisovans are the closest extinct relatives of currently living humans.…

Before Jane Goodall’s discovery scientists believed that non-human primates lived simple life. It turns out that they are highly intelligent, emotional creatures that live in complex societies. This new discovery lead people to feel compassion and concern for the animals. Leakey’s once said “new we must redefine tool, redefine man, or consider chimpanzees as humans”. We now see that we are not alone with being advanced that there are other non-human primates that also are advancing.…

Studying the bonobo has given researchers much insight into our closest living relative. Unfortunately, according to a number of different journal articles, the bonobo is on the verge of extinction. However, in order to understand the conservation issues associated with the bonobo, we must first be able to classify the animal with respect to its families and groups. The bonobo is classified according to the taxonomic hierarchy. Bonobos belong to the superfamily Hominoidea that includes apes and humans, and the family of great apes. The subfamily bonobos belong to is the Ponginae with the genus Pan. The genus Pan includes primates such as the bonobos and chimpanzees. The bonobo is known as the species called paniscus, while the chimpanzee is troglodytes. Finally, the evolutionary characteristics of the genus Pan include "knuckle walking" and "thin teeth" (Mcgrew 4). Now that we have an idea of the classification of the bonobo we can begin to understand why it must be protected.…

In the book “Lucy: the beginnings of Humankind” by Donald Johanson the author himself writes his journey of how his friend Tom Gray and himself experienced the most surprising encounter with the oldest fossil of a hominid that they later called Lucy. Donald Johanson and Tom Gray are pale anthropologists and are very well known for their discovery of Lucy. At the beginning of the book the author writes in the first person illustrating how rare it is to find fossils, many who study in this field sometimes have no luck in finding such extraordinary old fossils. Johanson feels “lucky” to have been able to find such fossils that many have been trying to find without any luck. When Johanson and Gray were at a camp in the Afar desert, they went exploring for sediments, fossils, traces that would lead them to a new discovery. They realized that many of the fossils that they were finding on their way had already been found, but luckily before they were about to leave back to the camp Johanson found part of a hominid arm. At first Gray did not wanted to believe Johanson, but then they began to form the puzzle of what it was a hominid.…

One of the main reasons why we are so interested in the other primates is that by looking at them we can obtain some ideas of what our ancestor must have been like a few millions years ago. Even though, we are not descended from any modern-type monkey or ape, our lineage does appear to have gone through stages in which we were a medium-sized, reasonably intelligent creature with good binocular vision, hands that were good at manipulation and the ability to climb trees. An evolutionary trend in primates involves the development of offspring both before and after birth and their integration into complex social systems. Another trend in primate evolution has been toward a more elaborate brain. In addition to brain size and gestation periods, social organization also demonstrates and plays an important role in primate evolution due to its complexity and hierarchy.…

For several centuries, it has been researcher’s goal in science to find the human race, ancient ancestry. From the time of Charles Darwin’s, Theory of Evolution, anthropologists, paleontologist and other researchers from various fields have been discovering and identifying human origins. The quest to find human’s oldest ancestor was the missing link in the human evolution tree. The “missing link” was eventually discovered in Hardar, Ethiopia by Dr. Donald Johanson, an American paleoanthropologist. According to Johanson, Lucy (Australopithecus afarensis) represented the missing link between apes and humans. She was our oldest human ancestor, the ape who walked upright. According to Dr. Donald Johanson, Lucy was one of the greatest paleoanthropological finds of the 20th century, but to others, Johanson’s discovery and methodology of identifying Lucy had many flaws and contradictions to his theory.…
