What Sets Humans Apart From Other Creatures ?

After reading the introduction to Homo Sapiens by Dr. Yuval Noah Harrari, I stumbled across a fascinating video that explains what sets Homo Sapiens apart; how their physiological features and brains helped them to use language and therefore gave them the edge over their competitors to build empires and conquer the planet earth.
Titled "Homo Sapiens vs Neanderthals | The Evolution of Language" it can be found here:

Dr. Jean-Michel Geneste at the National Centre for Prehistory in France described how 200 thousand years ago Homo Sapiens and Neanderthals developed technical skills and tools to make food of animals and possibly Neanderthals had thoughts similar to ours. However, only homo sapiens were able to develop complex relationships of objects which in turn allowed them to represent objects and animals in paintings - some of the more recent paintings are found in the 30,000 years old Lascaux Caves. What advantage do modern humans or Homo Sapiens have over Neanderthals who at one time made extensive wars for survival and controlled much of the land? Dr. Jefferey Laitman at Mount Sinai School of Medicine continued research and found that it was at the base of the skull that the larynx in modern humans developed and made it possible for humans to communicate through language. Human babies in their very early years are similar to monkeys as they breathe through the nose and eat through the mouth. However, as human babies get older the larynx can choke the person on food. This remains a possibility throughout life. But in human children, the  larynx leads through the throat to a wider tube which in turn makes it possible for humans among all animals to use the vocal cords connected to the brain. To be able to articulate in language what we mean gives us an advantage to communicate much faster and create cultures around tribes which then developed in ancient civilizations.
Dr. Ian Tattersall at the American Museum of Natural History comments: The essential advantage of  Homo Sapiens Cro-magnons in Lascaux over Neanderthals is precisely the ability to communicate in symbolic mental processes, and throughout their descendants produce sculptures, and artistic works that reflected their thought, and allowed them to share their findings. From generation to generation, Homo sapiens have been able to accumulate knowledge and use it for their societies.
Dr. Richard Dawkins, professor of evolutionary biology at Oxford University, indicated that genetics lasted for the first four billion years of life's history then, quite suddenly, genetic evolution gave rise to creatures with big brains which developed a second kind of genetics which is language and the transmission of linguistic information down through generations. It is clear from what he said that the the language development was recast into cultural development. This was the beginning of ancient civilizations but with advances in thought we not only left behind the old thoughts but have also attained complex technology. Development in human understanding continues to impress many people. The well-known Dr. Noam Chomsky, professor emeritus of history and philosophy at MIT, says that the choice in the future is a question of history not evolution and it is up to us in using human intelligence to save life on this planet and to support the needy with the technology developed in so many fields - Humanity is capable from the study of its history, to bring about its own destruction or live in peace and preserve life.
It is really relationship that sets humanity apart from animals...The possibility of life is embedded in mankind created in the image of God (Genesis, 1: 27). The world only reflects God's goodness and providence. In Christ, God prepares us and restores us through his Spirit to eternal life...
In his "introduction to Christianity", Joseph Ratzinger wrote "God, too, is absolute permanence, as opposed to everything transitory, for the reason that he is the relation of three Persons to one another, their incorporation in the 'for one another' of love, act-substance of the love that is absolute and therefore completely 'relative', living only 'in relation to'. As we said earlier, it is not autarchy, which knows no one but itself, that is divine; what is revolutionary about the Christian view of the world and of God, we found, as opposed to those of antiquity, is that it learns to understand the 'absolute' as absolute 'relatedness', as relatio subsistens."
