In the developmental history of mammalian heart, it is observed that it passes through a two chambered fish like heart, three chambered frog like heart and finally four chambered stage. To which hypothesis can the above cited statement be approximated?
1 Lamarcks principle
2 Biogenetic law
3 Hardy -Weinberg law
4 Mendelian principles
Explanation:
According to biogenetic law, during the development of animal heart it passes through ancestral adult stages.

1 Bird and reptile
2 Bird and mammal
3 Reptile and amphibia

Some of the evidences of organic evolution are
1 Occurrence of analogous and vestigial organs
2 Occurrence of homologous and analogous organs in different animals
3 Occurrence of only analogous organs in different animals
4 Occurrence of homologous and vestigial organs in different animals
Explanation:
Evidences are only way which can prove all proposed theories of evolution so far.Evidences are fossils, comparative anatomy and embryo development pattern. Comparative anatomy explains about the organisms evolved as a result of natural selection or genetic drift and organisms having same ancestors. Two types of comparative ancestors are homologous and analogous organs.

Among the following sets of examples for divergent evolution, select the incorrect option:
1 Brain of bat, man and cheetah
2 Heart of bat, man and cheetah
3 Forelimbs of man, bat and cheetah
4 Eye of octopus, bat and man
Explanation:
Divergent evolution is development of same structure along different directions due to adaptations to different needs. Divergent evolution occurs in homologous organs.Examples of Brain, Heart and Forelimbs of vertebrates are homologous organs and they have developed along different directions due to adaptations to different needs whereas eye of octopus, bat and man are examples of analogous organs showing convergent evolution.
