This post is for a debate to know on what basis humans are called (Ashraf-ul-Makhloqat)
Humans are said to be the Crown prince among all the creatures, but on what basis, what differentiate humans from other animals ?? I have following reasons - theories to start with, please contribute and correct me where I am wrong.
1) Intelligence
the first and the most probable factor is of intelligence level of humans and rest of the creatures, but question is, are humans really more intelligent than animals??
But, researches show that Animals, birds, dolphins, possess better intelligent mind than humans,
• Monkeys can solve puzzle faster and accurately than an adult trained human. (BBC)
• Sea lines can solve math problems
• Parrots can learn to speak (Alex, a parrot who was famous for his ability to learn, differentiate between things materials, and solving math (NY times)
• Pigeons can create map in their mind and have sharp memory
• An experiment revealed that animals and birds who live in intense – hard environment where they have to survive hard are more intelligent and can think better than those who live in an easy environment where they have plenty of food.
• A chimpanzee can remember 9 random numbers shown for 0.6 seconds on computer screen and can re-call them in respective order
• Another chimpanzee can talk to scientists with the help of symbol chart.
• Animals learn faster than humans, think better, think fast, have sharp memory, can feel pain, can understand what humans expect from them, and can predict and see in future, can predict natural disasters, floods, winds, storms, and have better of life than humans.

These were few instances, which show that animals are better in intelligence than humans,
An adult human cant compete in intelligence with animals and birds in any sense.
Then what is the main reason to address human as “ Ashraf-ful-Makhloqat “ ???
Some other traits of animals in contrast with humans are ;
1. Animals do not inflict pain on others for the pleasure of doing it , but humans do
2. Animals are not sexcual beast , they do not have relations without main purpose of breeding. But man is the a sexual beast , Vulgarity , Obscenity and indecency are strictly confined to man. Humans make relations by force and with many
3. Animals are not greedy as are humans, they do not hoard , they accumulate only sufficient grain enough for their season.
4. Animals do not kill other animals for the sake of fun , but humans do,
This shows the Moral behavior of humans is very dis-appointing and low as compare to humans.
Then what are distinctive features of humans that earned them a Crown to rule the Earth ???
