The variation in beak type enables the different individuals in a population to feed on different food sources.
The shape of the beak is key to determining the primary food source of the bird. Certain birds species have specialized beaks, but within populations of those species, there is a variation in beak shape.
This gives the population the ability to respond to changes in the environment and availability of different food sources.
For example, if because of a dry period there is a shortage of fruit, some individuals in the population have the beaks that enable them to feed on other things, survive and leave offspring.

Proteins carry out various functions for your body to keep you healthful. every gene consists of instructions that decide your functions, together with eye shade, hair coloration, and height. There are extraordinary variations of genes for every characteristic.
Allan Maxam and Walter Gilbert posted a DNA sequencing method in 1977 based on the chemical amendment of DNA and the next cleavage at unique bases. additionally referred to as chemical sequencing, this method allowed purified samples of double-stranded DNA for use without further cloning.
