Fossil Found Early Evolution
people from the independent analysis of fossil primates found in states in mid-May and is not a direct human ancestor, as previously claimed. Fosil yang umurnya ditaksir sekitar 47 juta tahun itu diberi nama ilmiah dan dijuluki sebagai Darwinius masillae Ida. Fossils of an age estimated to be about 47 million years old were given the scientific name and dubbed as Darwinius masillae Ida. Oleh penemu sebelumnya fosil ini dianggap sebagai "keajaiban dunia kedelapan ", dan masih ada sangkut paut dengan teori evolusi Darwin menurut para peneliti yang mengumumkannya. The inventor of this fossil previously deemed as the "eighth world wonder", and still there is nothing to do with Darwin's theory of evolution according to the researchers who announced it. Para penemu melihat dari struktur tulang dan pembentukan lengan dan terutama bagian kaki. The inventors saw the formation of bone structure and especially the arms and legs.
Para penemu mengatakan, fosil tersebut adalah missing link atau rantai yang hilang antara manusia dan dunia hewan. The inventors say, the fossil is the missing link or missing link between humans and the animal world. Dan bukan mata rantai langsung yang menghubungkan antara Primata dengan manusia. And it's not a direct chain linking with a human Primates. Erik Seiffert, peneliti utama studi baru mengatakan,"Pandangan yang menganggap bahwa Ida memiliki hubungan khusus dengan primata tingkat tinggi seperti monyet, kera dan manusia, merupakan pandangan minoritas dari awal. Jadi hal itu hanya mengejutkan banyak orang yang mempelajari paleontology primata.". Erik Seiffert, principal investigator of a new study says, "The view which assumes that Ida has a special relationship with the higher primates such as monkeys, apes and humans, is the minority view from the beginning. Thus it was only surprised many people who study primates Paleontology.". Ida merupakan dasar dan sebuah awal dari proses evolusi manusia dan hewan. Ida was the foundation and a beginning of the process of evolution of humans and animals.
After doing research experts find new Seiffert analysis begins with efforts to identify other primate fossils are Afradapis longicristatus, who allegedly has strong ties with Darwinius. Then the researchers compared the 360 specific anatomical features of 117 primate species living or extinct. The experts also compiling a family tree to make it easier to do the grouping. Analysis showed that both primates is located at the beginning of twigs from the branches that produce lemurs, and distant from the lineage of monkeys and apes. Furthermore, the researchers say that both types have no modern descendants. But it can be said as a pioneer of the evolutionary process.
The new study published in Nature, opposed the idea that Darwinius is an important part of the human lineage. Researchers previously have chosen Ida feature in the face, teeth, and feet similar to the higher apes, but a new research team, believes that these features may be the result of convergent evolution. The researchers who discovered Darwinius cling to their findings, and maintain that Ida was a spectacular discovery. They also said that the framework is much more complete than Darwinius Afradapis and shows the characteristics of higher primates, such as bones in the foot By gambling but surely Seiffert said that Darwinius not play a significant role in the origin of humans, fossils found in more closely related to lemurs and lorises. Seiffert said, "last ancestor Darwinius is a common progenitor that gives rise to all primates" must be recognized that the beginning of all living creatures could be from some form of life.
