Heritable variation is one of the four most important factors that affect whether natural selection can occur. These factors include

1) Heritable variation

2) Descent with modification

3) Struggle for survival, and necessarily if the others are satisfied

4) Survival of the fittest.

Heritable variation allows for possibly beneficial, negative, or even neutral mutations to get filtered during each generation by natural selection--weeding out negative mutations, passing on positive and neutral ones. Without heritable variation, species would quickly fall victim to parasites who take advantage of identical genetic material in a population and evolution would not occur.

Variation is the raw material of evolution.

The Kerala government has implemented Green Protocol for making weddings more naturally in the state. The purpose of the initiative is to reduce the use of plastic in daily life. With the implementation of the protocol, use of plastic and other non-degradable articles including disposable glasses and plates and thermocol decorations will be discouraged at marriage functions. Inspections will be held at marriage halls, convention centres and hotels and other venues of the wedding ceremony in this regard and action would be taken if the protocol is violated. The state nodal agency for sanitation ‘Suchitwa Mission’ has already launched the initiative in Kannur, Ernakulam, Kollam and Alappuzha on a pilot basis. As per officials, the protocol would be implemented in the rest of the districts soon.
