  2. Evolution of insects - Wikipedia

    en.wikipedia.org/wiki/Evolution_of_insects

    Evolution has produced astonishing variety of appendages in insects, such as these antennae.. The most recent understanding of the evolution of insects is based on studies of the following branches of science: molecular biology, insect morphology, paleontology, insect taxonomy, evolution, embryology, bioinformatics and scientific computing.

  3. Timeline of entomology – prior to 1800 - Wikipedia

    1800–1700 BC, Minoan jewellery, Malia, Crete: two golden bees over a honey comb Entomology, the scientific study of insects and closely related terrestrial arthropods, has been impelled by the necessity of societies to protect themselves from insect-borne diseases, crop losses to pest insects, and insect-related discomfort, as well as by people's natural curiosity.

  4. Convergent evolution - Wikipedia

    en.wikipedia.org/wiki/Convergent_evolution

    Convergent evolution of many groups of insects led from original biting-chewing mouthparts to different, more specialised, derived function types. These include, for example, the proboscis of flower-visiting insects such as bees and flower beetles, [50] [51] [52] or the biting-sucking mouthparts of blood-sucking insects such as fleas and mosquitos.

  5. Insect - Wikipedia

    en.wikipedia.org/wiki/Insect

    The evolution of insect wings has been a subject of debate; it has been suggested they came from modified gills, flaps on the spiracles, or an appendage, the epicoxa, at the base of the legs. [121] More recently, entomologists have favored evolution of wings from lobes of the notum , of the pleuron , or more likely both. [ 122 ]

  6. Insect flight - Wikipedia

    en.wikipedia.org/wiki/Insect_flight

    In other winged insects, flight muscles attach to the thorax, which make it oscillate in order to induce the wings to beat. Of these insects, some (flies and some beetles) achieve very high wingbeat frequencies through the evolution of an "asynchronous" nervous system, in which the thorax oscillates faster than the rate of nerve impulses.

  7. Insect wing - Wikipedia

    en.wikipedia.org/wiki/Insect_wing

    The evolutionary origin of the insect wing is debated. During the 19th century, the question of insect wing evolution originally rested on two main positions. One position postulated insect wings evolved from pre-existing structures, while the second proposed insect wings were entirely novel formations.

  8. Mantis - Wikipedia

    en.wikipedia.org/wiki/Mantis

    Mantises are sometimes confused with stick insects (Phasmatodea), other elongated insects such as grasshoppers , or other more distantly related insects with raptorial forelegs such as mantisflies (Mantispidae). Mantises are mostly ambush predators, but a few ground-dwelling species are found actively pursuing their prey. They normally live for ...

  9. History of life - Wikipedia

    en.wikipedia.org/wiki/History_of_life

    The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
