In a clever but pernicious falsehood, our homegrown gadfly Tlaloc (see comment #9 to Genesis Sui Generis) has quoted Genesis as saying that the animals were created "after Adam". Now this may seem like a minor error, but it really is very critical. The system of evolution depends heavily on the fact that Man evolved last, and it would be a good trick to pretend that this was an idea original to that theory.
You only need to master one chapter of Bible to know that the contrary is true. The idea of Man emerging last is one of many ideas in Darwin's system that are plagiarized from the Bible. Here is the relevant text (my translation): "And the Lord said, let the Earth give forth the spirit of living creatures in its kind, ruminants and crawlers and livelier animals of the Earth in their kind, and it was so. And the Lord made the livelier animal of the Earth in its kind and the ruminant in its kind and all the ground-crawlers in their kind, and the Lord saw that it was good. And the Lord said: 'Let us make Man in our form, like our image, and they will manage over the fish of the sea and the birds of the heavens and the ruminants and over all the Earth, and over all the crawlers that crawl upon the Earth.' And the Lord created the man in His image, in the image of the Lord He created Him, male and female He created them. And the Lord blessed them, and the Lord said to them, 'Be fruitful and multiply and fill the Earth, conquering it, and manage over the fish of the sea and the birds of the heavens and all the life that crawls upon the Earth.' " (Genesis 1:24-28)
Later, in a verse that reviews the creation of Man, it adds as follows: "And God, the Lord, fashioned Man, dust from the Earth, and He blew into his nostrils a soul of life, and the Man became an ensouled life." (ibid 2:7)
Strip this of the religious language and note the following points. 1) Man is created last. 2) He/she is designed to be stronger and more capable than the rest, sufficient to exercise control. 3) The Earth is an active agent in the process of "giving forth" all animal and human life forms. 4) All animal and human bodies emerge in some way from the physical materials already present in the Earth.
Now project your mind back to prehistoric time and you will understand that none of this was "necessary" in order to invent an effective religion or mythos. This is simply an amazing window into the science of Nature, one into which Darwin just took a little peek (and still got plenty of detail wrong).
