In 1957, Haldane articulated Haldane's dilemma, a limit on the speed of beneficial evolution, an idea that is still debated today. [8] He is also remembered for his work in human biology, having coined "clone", "cloning", and "ectogenesis". With his sister, Naomi Mitchison, Haldane was the first to demonstrate genetic linkage in mammals.
Lynn's theory has been criticized for attributing causal relationship between correlated statistics. [ 160 ] [ 161 ] Lynn supports scientific racism more directly in his 2002 paper "Skin Color and Intelligence in African Americans", where he proposes "the level of intelligence in African Americans is significantly determined by the proportion ...
A parody is a creative work designed to imitate, comment on, and/or mock its subject by means of satirical or ironic imitation.Often its subject is an original work or some aspect of it (theme/content, author, style, etc), but a parody can also be about a real-life person (e.g. a politician), event, or movement (e.g. the French Revolution or 1960s counterculture).
A painstaking analysis of inclusive fitness, attachment theory and non-human primate social relationships, through a fascinating journey which ends with an anthropological account of social bonds in different cultures... It is a landmark in the field of evolutionary biology, which places genetic determinism in the correct perspective. [7]
In biology, a pair bond is the strong affinity that develops in some species between a mating pair, often leading to the production and rearing of young and potentially a lifelong bond. Pair-bonding is a term coined in the 1940s [ 1 ] that is frequently used in sociobiology and evolutionary biology circles.
The father of a child can develop the bond during the pregnancy of his partner, feeling attachment to the developing child. Research indicates that this may have some biological basis. [3] Statistics show that fathers' levels of testosterone tend to decline several months before the birth of the child. Since high testosterone levels are linked ...
An important aspect of the valence bond theory is the condition of maximum overlap, which leads to the formation of the strongest possible bonds. This theory is used to explain the covalent bond formation in many molecules. sp 3 hybridization in methane forms four equivalent sigma bonds with tetrahedral geometry.
His contributions to the theory of the chemical bond include the concept of orbital hybridisation and the first accurate scale of electronegativities of the elements. Pauling also worked on the structures of biological molecules, and showed the importance of the alpha helix and beta sheet in protein secondary structure .
