Answer 1

answer is below

Ans.1) Evolution is the sequence of gradual changes which take place in the primitive organisms over millions of years, in which new species are produced.

Darwin's theory consisted of two main points;

1) diverse groups of animals evolve from one or a few common ancestors;

2) the mechanism by which this evolution takes place is natural selection.

Ans.2) The following are the various evidences in favour of evolution:

Homologous organs: Organs with a common basic structural design but with different functions are said to be homologous organ. For example, forelimbs of a frog, lizard, bird and man.

The forelimbs of man are used for grasping, of lizard for running, of frog for propping up and bird for flying. They have different functions but have same structural pattern.

Analogous organs: The analogous organs have different basic structure but perform similar functions. For example, the wing of insects and the wing of birds, have a totally different anatomy and origin but they perform the same function of flying in air.

Evidences from fossils: The fossils also provide evidences for evolution. For example, the fossil Archaeopteryx looks like a bird but it bears a number of other features, which are found in reptiles. This observation provides a clue that birds have evolved from reptiles.

Ans.3) Type O is the most dominant blood.

Ans.4) ACQUIRED TRAITS

• Traits which are devloped in an individual due to special conditions.
• Cannot be transferred to progeny.
• They cannot direct evolute.
• Eg. Low weight of starving beetles.

INHERITED TRAITS

• Traits which are passed from one generation to next.
• They get transferred to progeny.
• They are helpful in evolution.
• Eg. colour of eyes and hair.
