Humans are the most intelligent animals on Earth.

Note before I begin: I specifically stated that round one was acceptance, and round two is opening arguments. Therefore I'd like to ask all voters to please disregard my opponent's first round argument. I would also like to insist that my opponent take the rules seriously and provide sources when it is their turn to debate. Thank you.Thank you to my opponent for accepting this debate. I look forward to a fruitful discussion. I will be arguing, in this case, that humans are the most intelligent animals on Earth. Admittedly, this is, to most people, considered obvious. However, in recent times, I have noticed that there care considerations that other animals are perhaps as intelligent or more intelligent, based on some standards, Dolphins, for example are often cited as an intelligent animal. I will be arguing that humans are absolutely the most intelligent species.Webster's dictionary gives this definition for intelligence and is the one I will be using:The ability to learn or understand or to deal with new or trying situations : reason; also : the skilled use of reason : the ability to apply knowledge to manipulate one's environment or to think abstractly as measured by objective criteria (as tests) The first thing I will deal with is "The ability to learn or understand or to deal with new or trying situations." Humanity exemplifies this trait like no other species- over the millenia humans have used tools to develop agriculture, fight off predators, and catch prey(1). This is a prime example of problem-solving. Such tool use is far more prominent in humans than any other species.The second part of the definition says, "the skilled use of reason". Reason is defined as such:The power of comprehending, inferring, or thinking especially in orderly rational ways.Once again, humans excel in this area. Humans, more than any known animal, have uniquely developed advanced mathematics (2), extensive scientific study (3), and philosophy (4). This shows a unique power of comprehension, inference, and rationality, found only in more limited extents in other animals. As a matter of fact, this debate could be considered proof of human reasoning skills, no matter who wins!The final part of the definition of intelligence that I will be dealing with is "the ability to apply knowledge to manipulate one's environment". Once again, perhaps more in this case than previous points mentioned, humans modify their environment extensively. This should be obvious to almost everyone, excepting, perhaps, extremely isolated peoples and infants. Humans have been known to create architecture, for shelter and various other reasons (5). Humans also modify their natural environment, planting and removing wooded areas, creating dams to stop rivers, and more (6). Finally, humans even domesticate plants and animals for food (agriculture, hunting dogs), work (horses, oxen), and play (emotional companion dogs) (7). This is something other animals do not do to nearly the extent that humans do.In conclusion, humans have evolved very adept brains with good reasoning skills and the ability to understand one another, have abstract thought, and modify their environments, making them, among other creatures on Earth, the most intelligent. Thank you readers, and thank you opponent. I look forward to your opening arguments.Sources:1- http://www.livescience.com...2- http://www.math.tamu.edu... 3- https://www.britannica.com... 4- https://historyofphilosophy.net... 5- http://www.historyworld.net...6- http://www.uni-kiel.de... 7- http://www.nationalgeographic.org...
