BIOLOGY ORIGIN AND EVOLUTION OF LIFE QUIZ-2
Dear Readers,NEET is the most famous and important medical entrance examination held in our country. This exam is an objective type, an offline test which includes 4 sections namely– Physics, Chemistry, Botany, and Zoology. The maximum marks that can be scored are 720 marks and have 180 questions. About half of the paper consists of questions from Biology, as the NEET exam essentially focuses on capacitating students to go for seats in medical courses. One of the most significant and crucial sections in the NEET exam is of Biology. It comprises of theories, descriptions, discoveries, diagrams, definitions, explanations of differences, and relations.

Q1. Homo sapiens neanderthalensis and Homo sapiens sapiens (Cro-magnon man), were originated from
Solution
(a) Homo erectus (erect man) appeared about 1.7 million years ago in middle Pleiostocene. Homo erectus was evolved from Homo habilis. He was about 1.5-1.8 metres tall. He was the progenater of two main sub-species Neanderthal and Cro-magnon man

Q2.Homo erectus lived about
Solution
(b) 1.5 million years ago

Q3. The idea of natural selection as the fundamental process of evolutionary changes was reached
Solution
(b) In 1831, Charles Darwin accepted an unpaid post of naturalist on the surveyship HMS Beagle, which spends the five years at the sea charting the east coast of South America and gave theory of natural selection. Alfred Russell Wallace had travelled widely in South America, Malaya and the Eastern Indian archipelago and come to the same conclusions as Darwin regarding natural selection. In 1858, Wallace wrote an essay, outline his theory and sent it to Darwin. This stimulated and encouraged Darwin and in July 1858, Darwin and Wallace presented papers on their ideas at a meeting of the Linnean Society in London. Over a year later, in 1859, Darwin published-‘On the origin of species by means of natural selection’.

Q4. Which of the following statements are incorrect?
I. Microbial experiment shows that when the pre-existing advantagoeus mutations are selected they will result in the observation of new phenotypes. Over few generations, this would results in speciation
II. Neanderthal fossils represents a human relative.
III. In 1938, a fish caught in South Africa happened to be a coelacanth (lobe fins) which was thought to be extinct. These animals evolved into the first living amphibian on both land and water
IV. Lichens can be used as water pollution indicators
V. Alfred Wallace, a naturalist, who worked in Malay Archepalago (present Indonesia) had also came to the similar conclusion on natural selection as reached by Darwinism
The correct option is
Solution
(d) Lichens are the indicator of air pollution not of water
(d) Lichens are the indicator of air pollution not of water
Q5.Which one is the largest ape among the given four genera of apes?
Solution
(a) Genera of apes are as follows (i) Hyalobates (the gibbon) It is smallest and most primitive of the apes (ii) Simia (the orangutan) It build nests on trees (iii) Pan (the chimpanzee) Most intelligent among apes. It can make tools, etc. (iv) Gorilla (the gorilla) It is the largest ape and very dangerous

V. Forearm of human and forelimbs of horse
The correct combination is visible in option
Solution
(b) Hands of man and wings of bat, forearm of humans and forelimbs of horses are the examples of homology because they have same or common origin but have different functions
(b) Hands of man and wings of bat, forearm of humans and forelimbs of horses are the examples of homology because they have same or common origin but have different functions
Q7.First human like hominid is known as
Solution
(b) Homo habilis; (homo = human; habilis = able) 2-1.5 mya. Brain of Homo habilis was one half the size of a modern human. They were more sophisticated with rudimentary speech

Q8.Which of the following is a pair of analogous organs?
Solution
(a) Contraclile vacuole in Amoeba and uriniferous tubule in frog are analogous organs. Analogous organs have different origin and structure but have same function. Similarly, on the basis of same function is called analogy. Both contractile vacuoles and uriniferous tubules are cocerned with osmoregulation.
