Set which includes only analogous organs is :
1 wings of butterfly, housefly and bat
2 hindlegs of horse, grasshopper and bat
3 wings of butterfly and Wingspread of bat and birds.
4 mandibles of cockroach, mosquito and honey bee.
Explanation:
The organs which have similar functions but are different in their structural details and origin are called analogous organs. The analogous structures are the result of convergent evolution. Ex. The wings of locusts (insects), wings of bats and wings of pigeon are analogous to each other. It is due to the fact that the basic structure of the wings of insects (locust), wings of bat and wings of birds (pigeon) are different. However, their function is similar.

Myrmecobius and Myrmecophaga are closely related and have similar adaptations for the same habitat. This phenomenon is
1 divergent evolution
2 homoplasv
3 convergent evolution
4 parallel evolution
Explanation:
Parallel evolution occurs when independent species acquire similar characteristics while evolving together and the same time in the same ecospace. An example of parallel evolution is extinct browsing horses and paleotheres. - Parallel evolution is one where two different organism evolve together having similar traits in similar habitat.

Some of the important evidences of organic evolution are:
1 occurrence of homologous and vestigial organs
2 occurrence of analogous and vestigial organs
3 occurrence of homologous and analogous organs
4 occurrence of analogous organs only
Explanation:
Important evidences of organic evolution are occurrence of homologous and vestigial organs. The organs which have the same fundamental structure but are different in functions are called homologous organs. The homologous structures are a result of divergent evolution. It indicates common ancestory. Ex. - The limbs of humans, cats whales, and bats. Vestigial organs are rudimentary anatomical structures that are retained in a species despite having lost their primary ancestral function. Example - Nictitating membrane (plica semilunaris) in human eyes, caudal vertebrae, vermiform appendix, wisdom teeth etc.

Which of the following is the oldest living fossil?
1 Architeuthis
2 Neopilina
3 Nautilus
4 Limulus
Explanation:
Neopilina shows a close relationship with fossils that existed about 400 to 500 million year ago. - Neopilina is the oldest living fossil. It is a connecting link between Annelida and Mollusca. It resembles Mollusca as it possesses a shell, a mantle and a large muscular foot. Its Annelid characters are presence of segmentally arranged gills, nephridia and muscles and a trochophore larva like stage.
