    ... the two organisms from head to toe, and from anatomy to embryo development. Similarities between the two organisms would provide some facts helpful in proving the humans and apes to be related. In comparing anatomy, a multitude of similarities is present. Both human and ape have diversified teeth, meaning a variety of tooth types such as molars, incisors, and canines. This also confirms that humans and apes are omnivorous, eating both meat and vegetables. Both lack an external tail and both are capable of reaching an upright posture as well as bipedal locomotion, walking on two legs. Humans and apes both have an appendix, which is an appendage that it believed to be used for the digestio ...

    ... this time, East African mammals adapted to drier more open grassland conditions. It was about this time that the new form of human emerged in Africa, a hominid with a much larger brain, excellent vision, and limbs and hips fully adapted to an upright posture. Paleoanthropologists call this hominid Homo Erectus, a human much taller than its diminutive predecessors, standing on average five feet six inches tall, with hands capable of precision gripping and many kinds of tool-making. The skull is more rounded than those of earlier hominids, but still had a sloping forehead and retreating brow ridges. Homo Erectus was more numerous and more adaptable than Homo habilis, and, on present eviden ...

  • Hominid Species - 1,918 words
    Hominid Species Hominid Species The time of the split between humans and living apes used to be thought to have occurred 15 to 20 million years ago, or even up to 30 or 40 million years ago. Some apes occurring within that time period, such as Ramapithecus, used to be considered as hominids, and possible ancestors of humans. Later fossil finds indicated that Ramapithecus was more closely related to the orang-utan, and new biochemical evidence indicated that the last common ancestor of hominids and apes occurred between 5 and 10 million years ago, and probably in the lower end of that range. Ramapithecus therefore is no longer considered a hominid. The species here are listed roughly in order ...

  • Neanderthalhomo Sapiens Hybrid - 1,068 words
    Neanderthal-Homo Sapiens Hybrid Implications of Neanderthal-Homo Sapiens Hybrid from the Abrigo do Lagar Velho (Portugal) In a recent excavation at Abrigo do Lagar Velho in Portugal, Duarte et al (1999) unearthed what was later to be recognized as early human skeletal remains which pointed to interbreeding between Neanderthal and Modern Humans during the mid - upper Palaeolithic transition. The morphology of the remains, belonging to a child of approximately 3-4 years old, indicates a Neanderthal typology in post-cranial features, and more modern cranial features. The find has been cited as evidence of hybridization between the two traditionally separate human lines, and offers an explanatio ...
