Although neutral evolution remains the consensus theory among modern biologists, [3] and thus Kimura's resolution of Haldane's dilemma is widely regarded as correct, some biologists argue that adaptive evolution explains a large fraction of substitutions in protein coding sequence, [4] and they propose alternative solutions to Haldane's dilemma.
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.
In humans, barring intersex conditions causing aneuploidy and other unusual states, it is the male that is heterogametic, with XY sex chromosomes.. Haldane's rule is an observation about the early stage of speciation, formulated in 1922 by the British evolutionary biologist J. B. S. Haldane, that states that if — in a species hybrid — only one sex is inviable or sterile, that sex is more ...

Haldane's Dilemma is not about the "efficacy of natural selection" -- it is about the inability of evolutionary genetics to cope with its own central issues. Haldane's Dilemma is not about the "extinction of a species" -- it is about the implausibility of high substitution rates. 4.158.231.177 08:52, 19 August 2006 (UTC)WalterR Yes, yes.
But if you take a step back and level set the stock market today, the muted action kind of makes a great deal of sense. Investors are facing a fresh dilemma — call it paralysis by analysis amid ...
