Darwinism designates a distinctive form of evolutionary explanation for the history and diversity of life on earth. Natural selection is the differential survival and reproduction of individuals due to differences in phenotype.It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. The premise of DNA barcoding is that by comparison with a reference library of such DNA sections (also called "sequences"), an individual sequence can be used to uniquely identify an organism to species, just as a supermarket scanner uses the familiar black stripes of Aphids are distributed worldwide, but are most common in temperate zones.In contrast to many taxa, aphid species diversity is much lower in the tropics than in the temperate zones. CBSE Class 6 Science Notes Chapter 9 The Living Organisms and Their Surroundings. Pet breeds live an average of four to five years, but may live as long as eight years.
