. Define the term evolution. Evolution cannot be equated with progress. Justify this statement

Best Answer

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

Evolution cannot be equated with progress. More and  more  complex  body  designs have emerged  and  evolved   over  time,  but  this  does  not  mean   that  the  older   designs are inefficient.  One of the simplest life for bacteria came into being very early in evolution is still

surviving in the present conditions. Bacteria  inhabits the  most  inhospitable habitats like hot springs, deep  sea, thermal vents  and  ice in Antarctica. But human beings,  have a body  design  which  is best suited  to their  environment and  supports their  existence.
