Why Variation is necessary in human evolution and variation is not necessary in human being |
| Answer» nice question..variation can sometimes be harmful to an individual. evolution is not a done and go process, rather it is a series of small events, or mutations which lead to a change in a particular population. this is not a fortnight process either. it takes hundred of years to be stabilized. now coming back to your question,say, there is a population of black colored moths. say, a mutational change caused a black color moth to be grey colored. As an individual, it would be hunted out easily and its chances of survival will be less. if this took place around industrial revolution, the progeny of the grey colored moth, would be benefited more.So, sometimes, or most of the times the survival of an individual depends on the environmental and geographical factors than looking it as success for a species. | |
