  2. Cold and heat adaptations in humans - Wikipedia

    en.wikipedia.org/wiki/Cold_and_heat_adaptations...

    Origins of heat and cold adaptations can be explained by climatic adaptation. [16] [17] Ambient air temperature affects how much energy investment the human body must make. The temperature that requires the least amount of energy investment is 21 °C (70 °F). [5] [disputed – discuss] The body controls its temperature through the hypothalamus.

  3. Adaptation - Wikipedia

    en.wikipedia.org/wiki/Adaptation

    Structural adaptations are physical features of an organism, such as shape, body covering, armament, and internal organization. Behavioural adaptations are inherited systems of behaviour, whether inherited in detail as instincts, or as a neuropsychological capacity for learning. Examples include searching for food, mating, and vocalizations.

  4. Climatic adaptation - Wikipedia

    en.wikipedia.org/wiki/Climatic_adaptation

    Changes in behavior, physical structure, internal mechanisms and metabolism are forms of adaptation that is caused by climate properties. Organisms of the same species that occur in different climates can be compared to determine which adaptations are due to climate and which are influenced majorly by other factors.

  5. High-altitude adaptation in humans - Wikipedia

    en.wikipedia.org/wiki/High-altitude_adaptation...

    Depending on geographical and environmental pressures, high-altitude adaptation involves different genetic patterns, some of which have evolved not long ago. For example, Tibetan adaptations became prevalent in the past 3,000 years, an example of rapid recent human evolution. At the turn of the 21st century, it was reported that the genetic ...

  6. Climate change adaptation - Wikipedia

    Figure 16.5 Some examples of these are building seawalls or inland flood defenses, providing new insurance schemes, changing crop planting times or varieties, and installing green roofs or green spaces. Adaptation can be reactive (responding to climate impacts as they happen) or proactive (taking steps in anticipation of future climate change).

  7. Organisms at high altitude - Wikipedia

    The adaptation of humans to high altitude is an example of natural selection in action. [2] High-altitude adaptations provide examples of ... usage for physical ...

  8. SAID principle - Wikipedia

    en.wikipedia.org/wiki/SAID_principle

    It demonstrates that, given stressors on the human system, there will be a Specific Adaptation to Imposed Demands (SAID). [2] For example, by only doing pull-ups on the same regular pull-up bar, the body becomes adapted to this specific physical demand, but not necessarily to other climbing patterns or environments.

  9. Cellular adaptation - Wikipedia

    en.wikipedia.org/wiki/Cellular_adaptation

    In cell biology and pathophysiology, cellular adaptation refers to changes made by a cell in response to adverse or varying environmental changes. The adaptation may be physiologic (normal) or pathologic (abnormal). Morphological adaptations observed at the cellular level include atrophy, hypertrophy, hyperplasia, and metaplasia. [1]
