  • Question 2
    1 / -0
    The cranial capacity was largest among the 
    Solution
    Neanderthals were a species of human in the genus Homo, which became extinct around 40,000 years ago. They were closely related to modern humans having DNA over 99.5% the same. Remains left by Neanderthals include bone and stone tools, which are found in Eurasia, from Western Europe and Central and Northern Asia and the Middle East. With an average cranial capacity of 1600 cm$$^3$$, the cranial capacity of Neanderthals is notably larger than the 1400 cm$$^3$$ average for modern humans, indicating that their brain size was largest.
    Therefore, the correct answer is option D.
  • Question 3
    1 / -0
    Homo erectus evolved during
    Solution
    Homo erectus appeared about $$1.7$$ million years ago in middle pleistocene. H. erectus evolved from Homo habilis. He was about $$1.5-1.8$$ metres tall.
  • Question 4
    1 / -0
    Which of the following was the transitional stage (connective link) between apes and humans?
    Solution
    Australopithecus ramidus is the most ape like hominid ancestor, who walked upright and is considered  to be missing link between hominids and apes. It is the oldest and most primitive of hominin fossil dating back to 4.4 million years.
    So, the correct answer is 'Australopithecus ramidus'
  • Question 5
    1 / -0
    Wings of pigeon, mosquito and bat show:
    Solution
    Wings of pigeon, mosquito, and bat perform the same function (flying) but have evolved from separate ancestral populations. This similarity developed in distantly related groups as an adaptation for the same function is called convergent evolution.
    So, the correct answer is convergent evolution
  • Question 6
    1 / -0
    Homo sapiens implies
    Solution
    Homo sapiens sapiens implies modern man. Modern humans have a cranial capacity of 1450-1600cm$$^3$$. It has been evolved in the world 25000-1000 years ago. It is further divided into Negroid, Caucasian, Eastern and Mongoloid.
  • Question 7

  • Question 8

    Solution
    • The most recent era of geologic time, from about 65 million years ago to the present is called a Cenozoic era.
    • The Cenozoic Era is characterized by the formation of modern continents and the diversification of mammals and plants.
    • A Cenozoic era is known as the age of mammals and modern flora because the largest land animals have been mammals during that time and formation and diversification of moderns flora took place.
    So, the correct answer is 'Age of Mammals and Modern flora'.
  • Question 9
    1 / -0
    Which of the following concept explains about the constant occurrence of allele frequencies generation after generation in a small population not influenced by evolution?
  • Question 10
    1 / -0
    There is no life on moon because there is no
    Solution
    Firstly there is no water on the moon which is the first and foremost requirement for the life. Life first started on the earth because of water and if no water we can imagine no life. Air is also required to breathe and no air is on the moon or we can say that oxygen is required by human beings to breathe is not enough on the moon for the survival.
