  • Question 1
    1 / -0
    The epoch of human civilization is 
    Solution
    The three eras of geological time scale is further divided into six periods, which are further subdivided into epochs. The holocene epoch is the current period. 
    So, the correct answer is 'Holocene'
  • Question 2
    1 / -0
    There are two opposing views about the origin of modern man. According to one view, Homo erectus in Asia was the ancestor of modem man. A study of variations of DNA, however, suggested African origin of modern man. What kind of observation on DNA variations could suggest this
    Solution
    The origin of human races is a much-debated point among scientists studying human evolution. Many scientists argued that different race evolved from Homo erectus independently and that each adapted to a different place-Orientals in Asia, Caucasians in Europe, Aborigines in Australia and so on. 
    Recently Scientists studying mitochondrial DNA from living human all over the world have argued that their research shows that all human races originated from one Homo sapiens ancestor in Africa. 
    So,  there are greater variations in Asia than in Africa.
  • Question 3
    1 / -0
    Hardy-Weinberg equilibrium is influenced by gene flow, genetic drift, mutation, genetic recombination and :
    Solution
    • Five factors that alter the Hardy-Weinberg equilibrium are Gene flow, Genetic drift, Mutation, Genetic recombination an Natural selection.
    • These factors disrupt the genetic equilibrium by changing the allelic frequencies within the population.
    So, the correct option is 'Natural selection'.
  • Question 4
    1 / -0
    Prehistoric man who gave a proper burial . to the dead for the first time was
    Solution
    Neanderthal Man used hides to protect their body and buried their Neanderthal Man builts huts and used animal hides as clothing.
    So, the correct option is 'Neanderthal Man'.
  • Question 5
    1 / -0
    Fossils of CroMagnon Man were discovered in
    Solution
    • Cro-magnon man was originated 50,000-10,000 years ago'
    • They lived in caves
    • The first fossil was discovered in 1868.
    • Large forehead.
    • well developed speech
    • Semi-circular and large jaw.
    • Cranial capacity- 1650 c.c.
    So, the correct answer is '1868'
  • Question 6
    1 / -0
    Which is the most recent in human evolution? 
    Solution
    Modern man age of appearance is 25000 yrs ago and Neanderthal Man age of appearance is 100000 to 34000 age ago that's why Answer is Neolithic
     So, The Correct answer is 'Neolithic'
  • Question 7
    1 / -0
    In a Hardy-Weinberg population, the frequency of allele A of gene A $$ a $$ is 0.4. What is the frequency of allele $$a$$?
    Solution
    • According to the Hardy-Weinberg principle the gene pool (total genes and their alleles in a population) remains constant. This is called genetic equilibrium. Sum total of all the allelic frequencies is 1. 
    • So, the sum of Allelic frequencies,
    A + a = 1 
    0.4 + a = 1
    a = 0.6
    So, the correct answer is '0.6'
  • Question 8
    1 / -0
    Which one is correct 
    Solution
    A.Correct option -A
    B.Explanation for correct option -A

    • Cro-Magnon man was an excellent toolmaker and a very fine artist as they drew various pictures on the walls in their caves.
    • They were first to domesticate dogs. Also, they were religious.
    • They showed many features which depicted that they were civilized and able to learn new activities.
    • Thus they are known as the real ancestors of man. 
  • Question 9
    1 / -0
    Which of the following is correct regarding evolution of mankind? 
    Solution
    After Java and Peking Man there was appearance of Neanderthal Man whose age of appearance was 70,000 to 40,000 years ago and that time Cro-Magnon Man  appearance was 34000 to 40000 years ago so they lived together.
    So, the correct answer is 'Neanderthal Man and Cro-Magnon man lived together'
  • Question 10
    1 / -0
    What is correct 'sequence of Man, taxonomically starting from super family to subfamily
    Solution
    Taxonomic position of Man is, 
    Order - Primates
    Sub order - Anthropoidea
    Super family - Hominoidea
    Family - Hominidae
    Sub family - Homininae
    So, the correct answer is 'Hominoidea, hominidae, homininae'
