humans are classified as Homo sapiens. However‚ exactly 157 years ago‚ a completely new species is recognized by Johann Fuhlrott in a limestone quarry of the Neander Valley in Germany. In August 1856‚ a skull cap‚ two femora‚ three bones from the right arm‚ two bones from the left arm‚ a part of the left ilium‚ fragments of a scapula‚ and ribs are excavated and put together into a type specimen named Neanderthal 1. This specimen is believed to be a whole new species: Homo neanderthalensis. Scientists

average fully grown adult Homo sapiens is approximately 1200 to 1600 cubic centimetres and weighing three pounds. In comparison‚ the earliest trace of human ancestors‚ the Australopithecus clan had brains slightly greater than apes‚ around 400 cubic centimetres. Anatomically the Australopithecus were bipedal akin to humans‚ but intellectually akin to primates‚ which suggests that bipedalism preceded the growth of the brain on the timeline of human evolution. The next ancestors‚ Homo habilis had an increased

Introduction to Hominid Evolution Hominid evolution is the theory of the origins of the human species (Homo sapiens). Current understanding of human origins is obtained largely from the findings of paleontology‚ anthropology‚ and genetics. Of all primates‚ humans share particularly close affinity to other members of a group known as hominoids‚ or apes. Humans and their immediate ancestors‚ known as hominids‚ are notable among hominoids for their bipedal locomotion (Using two legs for walking)

evolution is the evolutionary process leading up to the appearance of modern humans. While it began with the last common ancestor of all life‚ the topic usually covers only the evolutionary history of primates‚ in particular the genus Homo‚ and the emergence of Homo sapiens as a distinct species of hominids (or "great apes"). The

as vegetarian is centered on the characteristics of the human body compared to carnivorous animals. It argues that because humans don’t have claws or pointed teeth we shouldn’t eat meat. However‚ I found that the digestive and dental system of homo sapiens serves as an example on omnivorous adjustment because the incisor teeth and canine are good to tear cooked meat into pieces‚ whereas the molars are needed to grind vegetable matter. Furthermore‚ vegetarians argue that carnivorous animals have smaller

characterised by speciation. The term speciation refers to “the formation of new and distinct species in the course of evolution”. Recently‚ experts in the field of evolution have given special emphasis to the new and most controversial issue of Homo floresiensis. Homo floresiensis (known as the Hobbit Man and LB1) is the little bodied and an extinct species that was discovered from a fossil and simple stone tools in 2003 on the island of Flores in Indonesia. Scientists indicate that the fossil belongs to

One hundred twenty-thousand B.C.E. homo sapiens sapiens emerge which displaces other human species. In thirty-thousand to twenty five thousand B.C.E. humans first travel to Americas.

570 million years that the kind of life forms we are familiar with began to evolve‚ starting with arthropods‚ followed by fish 530 million years ago (Ma)‚ land plants 475Ma and forests 385Ma. Mammals didn’t evolve until 200Ma and our own species‚ Homo sapiens‚ only 200‚000 years ago. So humans have been around for a mere 0.004% of the Earth’s history.
