The discovery of large amounts of genetic

variation in nearly all populations led to the

formulation of a different question: How is

genetic variation maintained? In many cases,

after all, natural selection removes genetic

variation by eliminating genotypes that are less

fit.

Many factors act to increase or maintain the

amount of genetic…[Read more]

In the 1960s there was considerable debate

regarding how much genetic variation actually

exists in populations. The common view was

that polymorphic loci are fairly rare. Then, the

development of the technique of gel

electrophoresis allowed biologists to examine

patterns of protein variation across

populations and to quantify genetic…[Read more]

Don’t rush, hurry and worry. The mind cannot handle so many things at one go. Faced with many tasks at hand, learn to do or take one thing at a time and doing that thing mindfully is important. Too many people get stressed up because they try to do too many things at one time. Remember:: Even super computers can and do break down.

We can land ourselves into a real mess and get stressed if we don’t care to plan and organise the things we do. More mishaps, accidents and errors are liable to occur bringing regret, remorse and tension. When we learn to neater, orderly, systematic and organized, our work environment becomes better and our mental states improve.

It is a fact of life that is sometimes we meet with things we don’t want and don’t meet with things we want. Everybody experiences this. Learn to accept things more wisely, with calmness, peace and balance. Of course, this takes practice and…[Read more]

As long as we do our best to realize our potential, what others achieve or get should not worry or trouble us. In fact, any feelings of jealousy, envy and enmity are indeed stressful. It would be very good and positive if we can rejoice at the success of others. Learn to share with them their joys of success. If we get inspiration from others’ succ…[Read more]

No two individual are same and they do not have the same capabilities, talents and potentialities. Setting goals which are beyond us will set undue stress upon ourselves. Get rid of over-ambition and unrealistic expectations. Having set realistic goals, we just need to do our best. It does not matter if not all goals can be met. It is not the end o…[Read more]
