Plant roots are far more than simple absorption organs: they can adjust their structure to better cope with water stress.

The genome is more than just its sequence; epigenetic features of DNA, like chemical tags that may be attached, or how it's organized and structured, can have a significant impact on gene expression ...

The endoplasmic reticulum is usually the biggest organelle in eukaryotic cells; it has various portions that serve different purposes; and it is the site of protein production, as well other other ...

Biological adaptation encompasses the range of structural, physiological and behavioural adjustments that organisms employ to survive and reproduce under changing environmental conditions. At the ...

Part I. Selection: Darwin and natural selection -- The group selection controversy -- For whose good does natural selection work? -- Part II. Adaptation: Darwin (and others) on biological perfection - ...

From a new paper published in Ecology Letters, this graphic shows examples of how interactions between temperature and sexual selection drive the co-adaptation of thermal physiology, thermoregulation ...

Genetic adaptation found: Quechua-speaking descendants of the Inca have unusually high copies of the AMY1 gene, aiding starch digestion. Rooted in domestication: The genetic shift aligns with the ...

Ancient genetic shift: Indigenous Andeans developed more copies of the AMY1 gene after potatoes became a dietary staple, boosting starch digestion. Survival advantage: Having ten or more AMY1 copies ...
