3、togeny recapitulates phylogeny (1874) the fetal development of an individual (ontogeny) is a speeded-up replay of millions of years of species evolution (phylogeny) Thomas Hunt Morgan, “Embryology and Genetics” (1934)第一次提出了胚胎发育的可能细胞分化机制:基因表达的时空分化在过去的30年中,我们已经发现了各种动物均使用的发育调控基因基本的细胞过程,形成了“进化发育生物学”这一分支
4、学科。进化发育生物学(evolutionary developmental biology):旨在阐明生物进化中发育过程和机制怎样改变以及这些改变如何造就过去和现在的生物多样性的一门学科。(Baguna and Garcia-Fernandez, 2003).物种之间发育基因的比较(Sean Carrol, 2005)常简称“Evo Devo”“Evo-devo“ is one of the newest areas of biology. It seeks to explain evolutionary events through the mechanisms of development
5、al biology. Its major questions are often the questions of the late 1800s which had been left waiting for other generations of biologists to unravel. We are those generations. These questions include: How did wings evolve? How did limbs evolve? How did vertebrates arise from invertebrates? How did v
6、ertebrates form their head? The Modern Synthesis of the 1930s and 1940s was the synthesis of evolutionary biology and population genetics. It is one of the greatest explanatory systems in science, and it explains incredibly well the origin, maintenance, and evolution of variations within populations
7、 of species. However, it did not identify the genes involved in these changes, nor did it explain the origin of higher taxa. Evolutionary developmental biology seeks to “complete” the synthesis by adding developmental genetics to population genetics. Traditional Evo-devo looks at the regulatory regi
8、ons of genes rather than their coding sequences. It emphasizes the arrival of the fittest rather than the survival of the fittest. _Stocks Locations toy intron1(847bp) locus sphinx (4257bp)_ _1 1 1111111111111 1 1 1 1 1 1 2 2 2 2 2 2 2 3 33 3 3 3 4Position 1 1 1 1 1 2 3 4 4 5 5 7 1 1 11111111122 2 2
