DNA - Does Not Answer (all questions)

Where a local bookstore thought Charles Darwin's 'Origin of Species' should be placed? In the fiction section! 

It sometimes becomes more and more perplexing when you start asking questions about life. One question will lead to another and pretty soon you will caught in a dreaded dead end with only more questions encircling your head. 

You ask yourself, if man evolved from apes, why are there still apes around? Wouldn't the apes and other primates have an innate desire at their DNA level to climb the stairway of evolution? Is it not the basic teaching of survival to forever improve oneself? For example, when the first generation discovers or invents something after so many generations of living in the dark about the subject matter, the second and subsequent generations learnt it so easily and improve it swiftly to take to great heights.

Just about 40 years ago, a hand held device to communicate face to face appeared fictional and is labelled 'Star Trek' technology. For the first practical computer to be invented, it took forever. Once a breakthrough was made, suddenly one by one everything falls in place. The same device for keeping time, to communicate though audio and visual means, to track one's speed and pace with GPS, to check facts literally at the tip of one's finger and to earn a living!  In the lower order animal kingdom, there have been anecdotal reports of insects of one gender developing gonads of the other within the same generation just because they were at brink of extinction. Why is that some group of people just stay the same, generation after generation, singing the same song of melancholy and hopelessness? (பஞ்சகோலம்)
At the same time, you cannot understand why some living animals have been downgraded in their evolutionary chain, if indeed true. The once fearsome ferocious sabre carnivorous tooth tiger of the feline ancestors has now evolved to become a domesticated omnivorous toothless cat roaming around our homes, harmless and in fact fearful of us! Of course, it could be natural selection after adverse living conditions on planet Earth.

Thinking of his ancestors, the sabre tooth tiger?
