A wheeled buffalo figurine—probably a children's toy—from Magna Graecia in archaic Greece [1]. Several organisms are capable of rolling locomotion. However, true wheels and propellers—despite their utility in human vehicles—do not play a significant role in the movement of living things (with the exception of the corkscrew-like flagella of many prokaryotes).
In gerontology, late-life mortality deceleration is the disputed theory that hazard rate increases at a decreasing rate in late life rather than increasing exponentially as in the Gompertz law. Late-life mortality deceleration is a well-established phenomenon in insects, [ 1 ] which often spend much of their lives in a constant hazard rate ...
A natural phenomenon is an observable event which is not man-made. Examples include: sunrise, weather, fog, thunder, tornadoes; biological processes, decomposition, germination; physical processes, wave propagation, erosion; tidal flow, and natural disasters such as electromagnetic pulses, volcanic eruptions, hurricanes and earthquakes.

Human locomotion in mud is improved through the use of cleats. Some snakes use an unusual method of movement known as sidewinding on sand or loose soil. Animals caught in terrestrial mudflows are subject to involuntary locomotion; this may be beneficial to the distribution of species with limited locomotive range under their own power.
There has been some controversy about the reality of Lévy flight foraging. Early studies were limited to a small range of movement, and thus the type of motion could not be unequivocally determined; and in 2007 flaws were found in a study of wandering albatrosses which was the first empirical example of such a strategy.

Mother Nature took no prisoners when she unleashed her wrath on Los Angeles at the beginning of 2025. Wildfires continue to rage in the area, and the death toll now stands at at least 27. Around ...
The human perception and understanding of biological motion in animal actions develops with age, usually capping at approximately five years of age. [10] In an experiment, with three-year-old, four-year-old, and five-year-old children and adults, participants were asked to identify PLD of animals actions such as walking human, running and ...
Cell division. All cells can be considered motile for having the ability to divide into two new daughter cells. [1]Motility is the ability of an organism to move independently using metabolic energy.
