We read in the Holy Quran
(2: 29) هُوَ الَّذِي خَلَقَ لَكُم مَّا فِي الأَرْضِ جَمِيعا
“He it is who created for you all that is in the earth”
and we see the following two instances scientifically upholding this declaration
If you look at the set of teeth of the carnivorous animals like the lion or tiger, they all have a pointed set of teeth i.e. suited for a carnivorous diet.
If you analyze the set of teeth of humans, you find that they have flat teeth as well as pointed teeth. Thus they have teeth suited for both herbivorous as well as carnivorous food i.e. they are omnivorous.
b)The digestive system of herbivorous animals can digest only vegetables. The digestive system of carnivorous animals can digest only meat. But the digestive system of humans can digest both vegetarian and non-vegetarian food.
This declaration is also supported by the Anthropocentric Worldview.
What is Anthropocentrism?
“Anthropocentrism is a world view that considers humans to be the most important factor and value in the Universe. In contrast, the biocentric world view considers humans to be no more than a particular species of animal, without greater intrinsic value than any of the other species of organisms that occur on Earth “. http://science.jrank.org/collection/1/Gale-Encyclopedia-Science.html
“According to Francis Bacon, “Man, if we look to final causes, may be regarded as the centre of the World…For the whole world works together in the service of man; and there is nothing from which he does not derive use and fruit…insomuch that all things seem to going about man’s business and not their own.” http://www.ecoling.net/worldviews_and_metaphors_-_final.pdf
“According to the German philosopher Immanuel Kant (1724–1804), humans alone have self-consciousness. Humans are therefore fundamentally different in rank and dignity from all other beings, while animals can be treated as means to human ends. The moral status of humans is thus awarded on the basis of “excellence.” Values are grounded in the fact that something is valuable for humans, and so human actions should be valued on the basis of their usefulness for humans.
Both scientists and the theologians have drawn on anthropocentrism to defend specific views about nature. scientists often on the basis of a perspective on evolution in which humans are considered the highest form of life on Earth, and theologians on the basis of a divinely mandated right for humans to exercise dominion over nature”. http://www.encyclopedia.com/doc/1G2-3404200025.html
Allah has created this whole world for human beings and made them His delegates. Although it is impossible for them to fully comprehend His wisdom, he demonstrates His signs to them so that they shall keep up the divine delegacy .
