Before the Cambrian explosion, [b] most organisms were relatively simple, composed of individual cells, or small multicellular organisms, occasionally organized into colonies. As the rate of diversification subsequently accelerated, the variety of life became much more complex, and began to resemble that of today. The seemingly rapid appearance of fossils in the "Primordial Strata" was noted by William Buckland in the s, [14] and in his book On the Origin of Species , Charles Darwin discussed the then inexplicable lack of earlier fossils as one of the main difficulties for his theory of descent with slow modification through natural selection.

    God i love anal. I Discovered it only three years ago. My girlfriend worked in the sex industry and was 18 years younger then me andВ wasВ a lap dancer. she liked anal more then regular. I was with her for three years and i will never forget the hot and intimate i had with her. She was 5 foot 3 and used to compete as an acrobatic gymnast as a youngster and due to an ankle injury she turned to dancing but the drugs have gotten the better of her lately. Such a shame. so much talent wasted.В
