Another force driving progressive evolution is the so-called "arms-race." Prey animals evolve faster running speeds because predators do. Consequently predators have to evolve even faster running speeds, and so on, in an escalating spiral. Such arms races probably account for the spectacularly advanced engineering of eyes, ears, brains, bat "radar" and all the other high-tech weaponry that animals display.

In a frenzy, kicking his legs and moving his arms in a swimmer's breaststroke, he managed to fight toward the rod. The closer he got to it, the stronger the web of force became. He did not give up. If he did, he would be back where he had been and without enough strength to begin fighting again. It was not his nature to give up until all his strength had been expended.
Philip José Farmer
Even now I cannot believe that I am still alive and writing this account of the emperor's death. I put my hands to my eyes, wondering if what I am relating here is not all a dream - or maybe it is not a dream: perhaps it is a delusion and I am mad, the victim of some extraordinary and monstrous hallucination. How comes it that when he is dead I am still numbered among the living?
Anna Comnena
Since the universe must contain millions of appropriate planets, consciousness in some form - but not with the paired eyes and limbs, and the brain built of neurons in the only example we know - may evolve frequently. But if only one origin of life in a million ever leads to consciousness, then Martian bacteria most emphatically do not imply Little Green Men.)
Stephen Jay Gould
If you search the scientific literature on evolution, and if you focus your search on the question of how molecular machines-the basis of life-developed, you find an eerie and complete silence. The complexity of life's foundation has paralyzed science's attempt to account for it; molecular machines raise an as-yet-impenetrable barrier to Darwinism's universal reach.

Very few people are aware that in each of our fingers, located somewhere between the firs phalange, the mesophalange and the metaphalange, there is a tiny brain. [...] It should be noted that fingers are without brains, these develop gradually with the passage of time and with the help of what the eyes see.... That is why the fingers have always excelled at uncovering what is concealed.
