All variations are in pieces do not have equal chance of survival why?
Answers
It is true that all variations and mutations in species will not have equal chances to survive in the environment.
According to 'Survival of the fittest', only the species which can adapt themselves to the environment can survive. Selection of the variants occurs by the different environmental factors. This forms the basis for evolution.
Also, when a new change or variation occurs it means that the DNA constitution and the bodily cell apparatus also undergo genetic changes which result in the formation of a new variant. However, this change in the DNA might not be able to survive in the new environment. So, the DNA may get damaged and may stop functioning regularly which will affect the survival of the variant.
The variations or the changes that are helpful and help in the evolution of the species will survive while the others will perish.
Answer:
No, all variation in a species do not have equal chances of surviving in the environment in which they find themselves. Depending upon the nature of variations, each individual would have different advantages of survival.
