While hominids have from hominoids and share certain common features, there are major differences as well. Hominoids have a smaller brain than hominids. They are quadrupeds, walking on all fours, but with flexible forelimbs. Hominids. by contrast, have an upright posture and bipedal locomotion (walking on two feet). There are also marked differences in the hand, which enables the making and use of tools. We will examine the kinds of tools made and their significance more closely later. Two lines of evidence suggest an African origin for hominids. First, it is the group of African apes that are most closely related to hominids. Second, the earliest hominid fossils, which belong to the genus Australopithecus, have found in East Africa and date back to about 5.6 mya. In contrast, fossils found outside Africa are no older than I .8 million years.
Q1: What are the key differences between hominoids and hominids mentioned in the passage?
Ans:
Q2: What lines of evidence suggest an African origin for hominids?
Ans:
Q3: What is the significance of the differences in hand structure between hominoids and hominids?

Hominids are further subdivided into branches, know-n as genus. of which Australopithecus and Homo are important. Each of these in turn includes several species. The major differences between Australopithecus and Homo relate to brain size. Jaws and teeth. me former has a smaller brain size, heavier jaws and larger teeth than the latter.
Q1: What are the two important genera within the hominid family, and what major differences distinguish them?
Ans:
Q2: How does Australopithecus differ from Homo in terms of brain size, jaws, and teeth?
Ans:
Q3: Why are the differences in brain size, jaws, and teeth between Australopithecus and Homo significant in the study of human evolution?
Ans:

Around 2.5 mya, with [the onset of a phase of glaciation (or an Ice Age). when large parts of the earth were covered with snow, there were major changes in climate and vegetation. Due to the reduction in temperatures as well as rainfall. grassland amas expanded at the of forests. leading to the gradual extinction of the early forms of Australopithecus (that were adapted to forests) and the replacement by species that were better adapted to the drier conditions. Among these were the earliest representatives of the genus Homo.
Q1: What significant environmental changes occurred around 2.5 million years ago, and how did they impact early hominids?
Ans:
Q2: How did the environmental changes during the onset of the Ice Age affect the distribution of vegetation?
Ans:
Q3: What was the ecological consequence of the environmental changes on early hominids, particularly the early forms of Australopithecus?
Ans:
Direction: Read the following Passage and Answer the Questions.
Fossils of Homo habilis have been discovered at Omo in Ethiopia and at Olduvai Gorge in Tanzania. The earliest fossils of Homo erectus have been found both in Africa and Asia: Koobi Fora and west Turkana. Kenya, Modjokerto and Sangtran, Java. As the finds in Asia belong to a later date than those in Africa. it is likely that hominids migrated from East Africa to southern and northern Africa, to southern and north-eastern Asia, and perhaps to Europe, some time between 2 and I .5 mya. This survived for nearly a million years.
Q1: Where have fossils of Homo habilis and Homo erectus been discovered, and what can we infer from their distribution?
Ans:
Q2: How do the timelines of Homo erectus fossil discoveries in Africa and Asia differ?
Ans:
Q3: What does the passage suggest about the duration of the migration and survival of hominids outside of Africa?
Ans:

About years ago. improvements in the techniques for killing animals are evident from the appearance of new kinds of tools such as spear-throwers and the bow and arrow. The meat thus obtained was probably processed by removing the bones. followed by drying. smoking and storage. Thus. food could be stored for later consumption. There were other changes. such as the trapping of fur-bearing animals (to use the fur for clothing) and the invention of sewing needles. The earliest of sewn clothing comes from about years ago. Besides. with the introduction of the punch blade technique to make small chisel-like tools, it was now possible to make engravings on bone, antler, ivory or wood.
Q1: What technological advancements in hunting and food processing are mentioned in the passage, and when did these developments likely occur?
Ans:
Q2: What changes in clothing production are described in the passage, and when is the earliest sewn clothing dated to?
Ans:
Q3: How did the introduction of the punch blade technique impact toolmaking, and what materials could be engraved using this technique?
Ans:

Another problem is that there is tremendous variation amongst living hunter-gatherer societies. There are conflicting data on many issues such as [the relative importance of hunting and gathering, group sizes. or the movement from place to place. Also. there is little consensus regarding the division of labour in food procurement. Although today generally women gather and men hunt. there are societies where both women and men hunt and gather and make tools. In any case, the important role of women in contributing to the supply in such societies cannot be denied. It is perhaps this factor that ensures a relatively equal role for both women and men in present-day hunter-gatherer societies. although there are variations. While this may be the case today, it is difficult to make any such inference for the past.
Q1: What challenges are associated with studying hunter-gatherer societies, as mentioned in the passage?
Ans:
Q2: How does the role of women in contributing to the food supply impact the gender dynamics in present-day hunter-gatherer societies?
Ans:
Q3: Why is it challenging to make inferences about the past based on contemporary hunter-gatherer societies, as mentioned in the passage?
Ans:

One such area where farming and pastoralism t4an around 10, ()CK) years ago was the Fertile Crescent. extending from the Mediterranean coast to the Zagros mountains in Iran. With the introduction of agriculture. more people began to stay in one place for even longer periods than they had done before. Thus permanent houses began to be built of mud. mud bricks and even stone. These are some of the earliest villages known to archaeologists. Farming and pastoralism led to the introduction of many other changes such as the making of pots in which to store grain and other produce, and to cook food. Besides. new kinds of stone tools came into use. Other new tools such as the plough were used in agriculture.
Q1: What is the geographical region where farming and pastoralism began around 10,000 years ago, and what is its significance?
Ans:
Q2: How did the shift to agriculture and pastoralism affect the lifestyle of early human communities, particularly in terms of settlement and housing?
Ans:
Q3: What were some of the technological and cultural developments associated with the introduction of agriculture and pastoralism in the Fertile Crescent?
