  2. Haldane's dilemma - Wikipedia

    en.wikipedia.org/wiki/Haldane's_dilemma

    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.

  3. Haldane's rule - Wikipedia

    en.wikipedia.org/wiki/Haldane's_rule

    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 ...

  4. J. B. S. Haldane - Wikipedia

    en.wikipedia.org/wiki/J._B._S._Haldane

    Haldane's article on abiogenesis in 1929 introduced the "primordial soup theory", which became the foundation for the concept of the chemical origin of life. He established human gene maps for haemophilia and colour blindness on the X chromosome, and codified Haldane's rule on sterility in the heterogametic sex of hybrids in species.

  5. Objections to evolution - Wikipedia

    en.wikipedia.org/wiki/Objections_to_evolution

    Objections to evolution have been raised since evolutionary ideas came to prominence in the 19th century. When Charles Darwin published his 1859 book On the Origin of Species, his theory of evolution (the idea that species arose through descent with modification from a single common ancestor in a process driven by natural selection) initially met opposition from scientists with different ...

  6. Adaptationism - Wikipedia

    en.wikipedia.org/wiki/Adaptationism

    The dilemma gave rise to a famous joke by the evolutionary biologist Haldane: "Teleology is like a mistress to a biologist: he cannot live without her but he's unwilling to be seen with her in public.'" David Hull commented that Haldane's mistress "has become a lawfully wedded wife. Biologists no longer feel obligated to apologize for their use ...

  7. Primordial soup - Wikipedia

    en.wikipedia.org/wiki/Primordial_soup

    Primordial soup, also known as prebiotic soup, is the hypothetical set of conditions present on the Earth around 3.7 to 4.0 billion years ago. It is an aspect of the heterotrophic theory (also known as the Oparin–Haldane hypothesis) concerning the origin of life, first proposed by Alexander Oparin in 1924, and J. B. S. Haldane in 1929.

  8. Group selection - Wikipedia

    en.wikipedia.org/wiki/Group_selection

    Projectile weapons led to changes in human hands and shoulders, such that humans are much better at throwing objects than the closest human relative, the chimpanzee. [ 53 ] In 2015, William Yaworsky and colleagues surveyed the opinions of anthropologists on group selection, finding that these varied with the gender and politics of the social ...

  9. Modern synthesis (20th century) - Wikipedia

    en.wikipedia.org/wiki/Modern_synthesis_(20th...

    As with Haldane and Fisher, Dobzhansky's "evolutionary genetics" [59] was a genuine science, now unifying cell biology, genetics, and both micro and macroevolution. [44] His work emphasized that real-world populations had far more genetic variability than the early population geneticists had assumed in their models and that genetically distinct ...
