For every one of these links, on the one hand, literally thousands of components (in rough numbers some 25,000 protein-coding genes and due to alternative splicing 90,000 The theory of the French naturalist Jean-Baptiste Lamarck is the concept of ​​use and disuse; That is, a characteristic that is used very frequently by a living being, gradually develops and strengthens until it meets the need of the species. One of the most important results has to do with the timeline of the giraffe and okapi divergence.
