Land mass occupies about

  1. 14 million hectares

  2. 140 million hectares

  3. 1400 million hectares

  4. 14000 million hectares
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Seen from space, the majority of the Earth's surface is covered by oceans – that makes up 71% of the surface of the Earth, with the remaining 29% for land.
So the correct option is '14000 million hectares'.
Multiple choice zoology universe and organic evolution darwin's theory of evolution process of evolution lamarckism

According to the neo-Darwinian theory, which of the following is responsible for the origin of new species?

  1. Mutations

  2. Useful variations

  3. Mutations together with natural selection

  4. Hybridization
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

According to the Neo-Darwinian theory, mutations together with natural selection results in origin of new species.

Neo-Darwinism is the "modern synthesis" of Darwinian evolution through natural selection with Mendelian genetics, the latter being a set of primary tenets specifying that evolution involves the transmission of characteristics from parent to child through the mechanism of genetic transfer, rather than the "blending process" of pre-Mendelian evolutionary science. Neo-Darwinism can also designate Charles Darwin's ideas of natural selection separated from his hypothesis of Pangenesis as a Lamarckian source of variation involving blending inheritance.

Which of the following is the evidence for Darwin's theory of common descent?

  1. There are patterns in the fossil record that suggest other species have diverged from a single ancestor species.

  2. There are biogeographic patterns in the distribution of species, for instance distinct bird species on an island tend to resemble one another, suggesting a common ancestor.

  3. There are common stages in the early embryological development of organisms representing several distinct vertebrate groups.

  4. All of above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Darwin's theory of common descent is supported by evidence from the fossil record, biogeography, and comparative embryology, all of which indicate shared ancestry.

Which of the following is responsible for evolution according to Neo-darwinism?

  1. Mutation

  2. Natural selection

  3. Adaptive radiation

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Natural selection is the core creative agent in evolution, mutations, variations, are also factors leading to the development of new species. Organisms more suited to the environmental conditions will survive empowering the forces of competition. The organism with beneficial mutations, stronger genotype will be the fittest and will survive. After successive generations, all the stronger gene pool leads to an evolution of new species.
