The gymnosperms formed the dominant vegetation on the earth during the geological period called
1 Carboniferous
2 Permian
3 Triassic
4 Jurassic
Explanation:
Triassic :- The Triassic period about 225 million year's ago belongs to Mesozoic era. The Mesozoic era is called as the era of medieval life and age of reptiles and gymnosperms. The Triassic period have abundance of cycads and conifers. During this period the gymnosperms formed the dominant vegetation on earth.

Abiogenetic theory of origin states:
1 spontaneous generation
2 organic evolution due to chemical reaction
3 origin of life due to pre-existing organisms
4 origin of life from blue green algae
Explanation:
Theory of spontaneous generation or abiogensis theory was proposed by Thomas Henry Huxley. The theory of abiogensis states that the evolution of living from non-living matter in spontaneous Ex. Meat left open generate flies and maggots .

Darwin proposed the theory of
1 inheritance of acquired characters
2 natural selection
3 recapitulation
4 continuity of germplasm
Explanation:
Natural selection :- Charles Darwin proposed the theory of Natural selection in 1858 , as a way to explain adaptation and speciation. Natural selection is differential success in reproduction and its product is adaptation of organisms to their environment. Thus, natural selection occurs through an interaction between the environment and the variability inherent in the population.

Which of the following is not Drawins conclusion?
1 Survival of the fittest
2 Struggle for existence
3 Inheritance of acquired characters
4 Origin of species by natural selection
Explanation:
Inheritance of acquired characters :Theory of inheritance of acquired character's was proposed by Jean Baptiste de Lamarck (1744-1829), a French biologist. The theory states that - Whatever on individual acquires (to possess) characters in its life time due to internal vital force, effect of environment. New needs and use and distance of organs, they are inherited (transmitted) to the next generations. The process continues. After several generation, the variations are accumulated upto such extent that they give rise to new species. As evolution of Giraffe from small neck and forelimbs to long neck and long forelimb. While Darwin's idea is related with natural selection which concluded the theory of origin of species through natural selection. Struggle for existence and survival of the fittest.
