Human Vs Animal
The level of intellect given to animals is at a level that they need to survive in this world. Human’s intellect and freewill, on the other hand, is such that they can aim to achieve big goals, plan them out, and act upon those plans. Not only that, but newer generations build upon the knowledge of previous generations, and that way human intellect keeps on expanding. On the basis of such intellect and freewill, humans have been able to achieve wonders such as landing on the moon, but animals have not evolved in that sense.
