Science states that human beings evolved from the ape- like creatures. Charles Darwin, the proponent of the evolution theory states in his book that there is fossil evidence that show the resemblance in these ancestors and present day human beings. Then one wonders why humans do not have tails, or better still, why some humans develop tail- like structures. Science has it that over time, all living things change and adapt to that change in a way that suits their living environment at any particular time. It is not surprising to state that in the next fifteen million years, Continue reading...
