Darwin would be delighted to witness what modern microbiology and molecular biology has achieved. Then the mapping of the DNA molecule, made between 1990 and 2003, for 13 years. Scientists can see which mechanisms are initiated from the beginning of an organism's development until he becomes an individual. The study of DNA is one of the greatest triumphs of modern science. It leads to our instincts / understanding of how animals grow and evolve to a level that Darwin could only dream of. The DNA molecule is really the real secret of life. It is a perfect system to store huge amounts of information that is necessary to create all kinds of creatures. DNA consists of an elongated molecule that spins round in a double spiral.
