Column A Column B A. Homologous (i) Convergent organs B. Abiogenesis (ii) Life originated from pre-existing life forms C. Biogenesis (iii) Divergent evolution D. Wings of bat and bird (iv) Life from non-living matter

A - iii, The homology means common ancestry. The evolution that gave rise to this kind of homology is called divergent evolution. B - iv, Abiogenesis is the natural process which shows how life arises from non-living matter, such as simple organic compounds. C - ii, Biogenesis is the theory showing how living things can only come from other pre-existing living things by the process of reproduction. D - i Wings of bats and birds do not share a common origin. Such organs are called analogous organs due to the analogy in function. The evolution giving rise to this kind of analogy is called convergent evolution. Column A Column B A. Homologous (iii) Divergent evolution B. Abiogenesis (iv) Life from non-living matter C.

Column A Column B A. Walked on limbs i. Ape Ïike B . Homo sapiens ii. Homo erectus C. Java man iii. Hugo de Vries D. Dryopithecus iv. Modern man

A— ii, Homo erectus was the first man on earth who walked on two limbs. They had undergone various morphological changes due to evolution. B — iv Homo sapiens were the modern man. They were one of the several species grouped into the genus Homo, but it is the only one that is not extinct. C — iii Java man is the extinct hominids known from fossil remains found on the island of Java. Hugo de Vries worked in the fields of heredity and its relation to the origin of species, framing the mutation theory. D — i Dryopithecus is the genus of extinct ape that is representative of early members of the lineage that includes humans and other apes. Column A Column B A. Walked on limbs ii. Homo erectus B .
