    This was followed by the spread of citrus species into Taiwan and Japan in the Early Pliocene (5.33 to 3.6 mya), resulting in the tachibana orange (C. tachibana); and beyond the Wallace Line into Papua New Guinea and Australia during the Early Pleistocene (2.5 million to 800,000 years ago), where further speciation events created in the ...

    en.wikipedia.org/wiki/List_of_domesticated_plants

    Places, where crops were initially domesticated, are called centers of origin. This is a list of plants that have been domesticated by humans. The list includes individual plant species identified by their common names as well as larger formal and informal botanical categories which include at least some domesticated individuals.

  5. Citrus taxonomy - Wikipedia

    en.wikipedia.org/wiki/Citrus_taxonomy

    Initially, many citrus types were identified and named by individual taxonomists, resulting in a large number of identified species: 870 by a 1969 count. [18] Some order was brought to citrus taxonomy by two unified classification schemes, those of Chōzaburō Tanaka and Walter Tennyson Swingle, that can be viewed as extreme alternative visions of the genus.

  6. Abiogenesis - Wikipedia

    en.wikipedia.org/wiki/Abiogenesis

    The emergence of life with increasing order and complexity does not contradict the second law of thermodynamics, which states that overall entropy never decreases, since a living organism creates order in some places (e.g. its living body) at the expense of an increase of entropy elsewhere (e.g. heat and waste production). [160] [161] [162]

  7. Evidence of common descent - Wikipedia

    en.wikipedia.org/wiki/Evidence_of_common_descent

    The normal mammalian condition is for the young of a species to experience reduced lactase production at the end of the weaning period (a species-specific length of time). In humans, in non-dairy consuming societies, lactase production usually drops about 90% during the first four years of life, although the exact drop over time varies widely ...

    Cycads were also common, as were ginkgos and tree ferns in the forest. Smaller ferns were probably the dominant undergrowth. Caytoniaceous seed ferns were another group of important plants during this time and are thought to have been shrub to small-tree sized. [16] Ginkgo-like plants were particularly common in the mid- to high northern latitudes.

  9. Lime (fruit) - Wikipedia

    en.wikipedia.org/wiki/Lime_(fruit)

    Most species and hybrids of citrus plants called "limes" have varying origins within tropical Southeast Asia and South Asia. They were spread throughout the world via migration and trade. The makrut lime, in particular, was one of the earliest citrus fruits introduced to other parts of the world by humans.
