Of course, some may argue human beings are animals, but for the sake of semantics and this post let's assume they are different.
Animal species unite amongst themselves, but human beings continue to fight. We separate ourselves based on our ideologies and thus create conflict. Animals work with their environment, humans mostly use up all of the resources, pollute, contaminate and destroy it.
Some may argue the following points:
Animals have no culture. Rebuttal: we see several social species such as chimps living in quite complex societies who's ritualistic behavior varies from location to location. The ways they interact, eat, play, and have even been observed contemplating their dead in makeshift funerals, could be considered culture depending on how you want to define that word.
Animals cannot create beauty/art/music. Rebuttal: we see many examples of great artists such as the intricate patterns created by spider webs, certain marine animals who can create beautiful patterns in the sand to attract mates and the amazing colorful patterns creatures such as a peacock can display. As far as music goes you simply can observe the beautiful songs so many birds can produce as evidence for animals' musical abilities.
Animals are not conscious. Rebuttal: If you say they are not conscious it begs the question, compared to who? Human beings? I would agree that animals are most likely not as self conscious as human beings. However that is not to say that there are not conscious beings at all. Their consciousness may not have quite evolved to the level of humans, at least not yet. However they may very well be conscious at some level but it would be very difficult for us to measure or detect exactly how much.
Human beings are better at surviving. Rebuttal: Many species such as insects can adapt to endure even the most catastrophic of environments much more easily than humans can.
Animals cannot communicate efficiently. Rebuttal: The human language is linear, purely symbolic, and mostly utilitarian. Some animals can communicate in much more efficient ways without using clunky words. A honey bee can perform a simple dance and all of the other bees will instantly know the exact location of that flower or hive. Wales can guide themselves towards each other from many miles away. Other species can use chemical scents to communicate many pieces of information to each other in a very short amount of time.
Animals have no sense of humor. Rebuttal: How do we know this? Simply because they cannot smile or audibly produce laughter does that mean they cannot appreciate humor or amusement? When baby cubs play and fall over each other are they amusing themselves? The mother looking on, does she find the situation amusing? One monkey may enjoy yanking on the other monkeys' tails and then running away, is this not a form of amusement and sense of humor? That funny monkey can't crack jokes but may have a quite enhanced sense of humor indeed.
Any other counterpoints for humans being superior to animals I would love to hear them. Thanks!
