The Structure of Evolutionary Theory (2002) is Harvard paleontologist Stephen Jay Gould's technical book on macroevolution and the historical development of evolutionary theory. [1] The book was twenty years in the making, [2] published just two months before Gould's death. [3] Aimed primarily at professionals, [4] the volume is divided into ...
The evolutionary biologists Kenneth McNamara and Michael McKinney stated in 2005 that of all the books that Gould wrote in his career, "the one with the most impact is probably Ontogeny and Phylogeny... to say that this work is a hallmark in this area of evolutionary theory would be an understatement.
Genetic architecture is incredibly important for understanding evolutionary theory because it describes phenotypic variation in its underlying genetic terms, and thus it gives us clues about the evolutionary potential of these variations. Therefore, genetic architecture can help us to answer biological questions about speciation, the evolution ...
In Darwin's theory of natural selection, more organisms are produced than can survive. Some have variations that give them a competitive advantage, and they have the best chance of surviving and procreating. The main element lacking in the theory was any mechanism that would allow organisms to pass on these favorable variations.
Evolution provides the field of biology with a solid scientific base. The significance of evolutionary theory is summarised by Theodosius Dobzhansky as "nothing in biology makes sense except in the light of evolution." [78] [79] Nevertheless, the theory of evolution is not static. There is much discussion within the scientific community ...
Here the evolution of human society (socialization) is ruled by psychological, economic, informational and communicative processes. For Teilhard there is a further stage, one of spiritual evolution , the Christing of the collective noosphere, in which humanity converges in a single divinisation he calls the Omega Point .
Hypochlorous acid is a natural molecule in the body but can also be used in skincare. Experts share how it’s used and why it’s the latest buzzy ingredient.
Fisher's principle is an evolutionary model that explains why the sex ratio of most species that produce offspring through sexual reproduction is approximately 1:1 between males and females. A. W. F. Edwards has remarked that it is "probably the most celebrated argument in evolutionary biology". [1]
