Key Characteristics of Five Hominid Groups Directions: Fill out the chart below using the History Alive (purple) textbook Chapter 2 and the five (5) readings on the resource table. The textbook offers very basic information, while the readings provide more information about each of the five (5) species of Hominids. HOMINID GROUP
Hominids evolved under natural selection pressures that selected for certain traits that conferred an advantage to individual consider the following list of traits. Choose the answer that correctly orders the evolutionary pattern of hominid traits. 1. Hominids lost their excessive body hair and gained more sweat glands.
Place the correct characteristics that distinguish the Dmanisi hominins from other Homo erectus finds on the skull below. small brain - The Dmanisi hominins have brain sizes around 550–650 cc, almost half the size of other Homo erectus finds from Africa and Asia.
Hominids lost their excessive body hair and gained more sweat glands. 2. Hominids evolved dark and hairless skin. 3. Hominids covered in thick hair and had light skin. C. 3, 1, 2= Hominids covered in thick hair and had light skin, hominids lost their excessive body hair and gained more sweat glands, and hominids evolved dark and hairless skin.
Hominid – the group consisting of all modern and extinct Great Apes (that is, modern humans, chimpanzees, gorillas and orang-utans plus all their immediate ancestors).
Chimps, gorillas, humans, and orangutans make up the family Hominidae; gibbons are separated as the closely related Hylobatidae. Thus constituted, the Hominidae includes 4 genera and 5 species. Its nonhuman members are restricted to equatorial Africa, Sumatra and Borneo.
A hominid is a member of the family Hominidae, the great apes: orangutans, gorillas, chimpanzees and humans. A hominine is a member of the subfamily Homininae: gorillas, chimpanzees, and humans (excludes orangutans). A hominin is a member of the tribe Hominini: chimpanzees and humans.
The Hominini form a taxonomic tribe of the subfamily Homininae ("hominines"). Hominini includes the extant genera Homo (humans) and Pan (chimpanzees and bonobos) and in standard usage excludes the genus Gorilla (gorillas).
In this website, you will learn about the five important groups of hominids named:Australopithecus Afarensis.Homo Habilis.Homo Erectus.Homo Sapiens Neanderthalensis.Homo Sapiens Sapiens.
In the 8 million years or so since the earliest ancestors of humans diverged from the apes, at least a dozen humanlike species, called hominids, have lived on Earth.
What Is Australopithecus? The genus Australopithecus is a collection of hominin species that span the time period from 4.18 to about 2 million years ago.

We do not know which hominin is the direct ancestor of Homo habilis, but anthropologist (1) suggests that similarities in the face, jaws, and teeth indicate that (2) is a good candidate. 1. Tim White - White is a prominent anthropologist who has analyzed many different hominin species. 2.
Correct Answer (s): Homo erectus appears in Asia and Africa at about the same time. - While Homo erectus almost certainly evolved in Africa, it spread to other parts of the old world, such as Asia, almost simultaneously.
Incorrect Answer (s): Homo erectus had a tall and rounded skull. In Africa, Homo erectus is mainly associated with Oldowan tools. Homo naledi is a new species of the genus Homo that is similar to Homo erectus, yet contains unique enough characteristics to warrant a separate species.
Not a Characteristic of Flores Fossils: date of one million years old - The Flores fossils date from 700,000 yBP to 60,000 yBP. This is remarkable considering the proliferation of Homo erectus at that time. a large brain size - In contrast to contemporary hominins, Homo floresiensis likely had a very small brain.
Click the island in the Dutch East Indies where the first Homo erectus fossil was found. Java - Eugene Dubois found a partial Homo erectus skull and complete femur on the island of Java in the late 19th century. Drag the developments in human evolution to their correct locations on the timeline.
Scientists attribute the change to the rise of cooking and increased access to high quality protein. Below is an image of one of the skulls from Dmanisi, Georgia, where several Homo erectus fossils have been found with surprising features.
Australopithecus-boisei 1. sagittal crest to anchor large chewing muscles - These adaptations reflect this genus’s diet of hard nuts and seeds. 2. large premolars and molars and thicker enamel - A likely explanation for these large teeth is extensive chewing of low quality foods, like hard nuts and seeds.
Appeared about 1.8 million years ago in Africa and eventually found throughout Africa, much of Asia, and parts of Europe. Survived until at least 300,000 years (and perhaps much later). Noted for having a much more modern body than earlier hominins with long legs and short arms.
Unlike other australopithecines this one is not from East Africa but from Chad in central Africa. Known from a lower jaw that appears similar in form to A. afarensis and dated to around the same time (3.6 million years ago).
The remains include most of the skull and teeth, arm and leg bones, pelvis, hands, and feet. The pelvis and foot bones indicate a primitive form of bipedalism but good climbing ability. It had a small chimpanzee-sized brain and a very apelike skull.
A species known from dozens of remains from Ethiopia to northern Tanzania and which lived from about 3.9-2.9 million years ago. Similar to the earlier A. anamensis (from which it is probably descended) in mixing bipedal locomotion with strong climbing ability. Probably used trees for food, protection and sleep. The brain size was chimpanzee-sized (roughly 400 cc). Males weighed around 50 kg and were about twice the size of females. Lived in a habitat that was generally wooded but with some wooded dry savannah.
Distinct from H. erectus in having a larger brain size (about 1100 cc) and fairly modern looking nose and cheekbones. They were about 1.6-1.8 m tall.
Probably used trees for food, protection and sleep. The brain size was chimpanzee-sized (roughly 400 cc). Males weighed around 50 kg and were about twice the size of females. Lived in a habitat that was generally wooded but with some wooded dry savannah.
Kenyanthropus platyops. Found at Lake Turkana, Kenya and dated to 3.2-3.5 million years ago. Noted for its small brain size and flat broad face. The teeth have thick enamel and the molars are small. It highlights the diversity of early hominins at this time.
