In which respect does Darwin's theory is wrong?
1 Survival of the fittest
2 Arrival of the fittest
3 High efficiency of reproduction
4 Origin of species
Explanation:
Darwin failed to explain arrival of fittest. But explained survival of fittest.

By the statement 'survival of the fittest', Darwin meant that:
1 The strongest of all species survives
2 The most intelligent of the species survives
3 The cleverest of the species survives
4 The most adaptable of the species to changes survives
Explanation:
Fitness refers to the reproductive fitness of an organism. This implies that the organism is able to survive up to the reproductive stage and is able to bear offspring and hence is able to pass on the genes to the next generation.

Which one of the following phenomena supports Darwins concept of natural selection in organic evolution?
1 Production of Dolly the sheep by cloning
2 Development of transgenic animals
3 Development of organs from stem cells for organ transplantation
4 Prevalence of pesticide resistant insects
Explanation:
Prevalence of pesticide resistant insects supports the natural selection theory. Example: Some years ago DDT was introduced against house hold pest. After some years they gained resistance against DDT and appeared some DDT resistant mosquitos. Later on in the population, mutant strains got well established and DDT resistant mosquito's replaced DDT sensitive mosquitos.

Lamarck explained his use and disuse theory with the example of
1 Marsupians
2 Giraffee
3 Finches
4 Tortoise
Explanation:
Lamarck use or disuse theory states that change in the environment causes changes in the needs of organisms living in that environment, which in turn causes changes in their behavior. Altered behavior leads to lesser or greater use of structures leads to enlarge or shrink. He explained it with the example of giraffe. Giraffee which were having scarcity of short plants, started stretching its necks and legs for eating the leaves on the tall trees which made its neck and legs to stretch which lead to change its neck and leg into a long neck and tall legs respectively.

Darwin's and Lamarck's theories of evolution both suggest that
1 Earth is 6000 years old
2 The main mechanism of evolution is the inheritance of acquired character
3 The interaction of organisms with their environment is important in the evolutionary process
4 Species are fixed
Explanation:
Both Lamarck and Darwin believed that living things had hereditary traits, traits they could pass on to their offspring. They believed that some traits were more useful than others, and that over time the more useful trait would become more common. The difference is that Lamarck believed that the changes an organism experienced during its life could be passed on. So for instance if a giraffe stretched its neck its entire life, it would have longer necked children.
