Gills' history

Gills, often referring to gills of fish and amphibians, are specialized organs that allow these creatures to extract oxygen from water, supporting their respiratory needs. Throughout evolutionary history, gills developed over millions of years, enabling aquatic life to thrive in various environments. In some species, gills can also indicate developmental stages, as certain amphibians possess gills during their larval phase before transitioning to lungs for terrestrial life. This adaptation illustrates the diversity of life and evolutionary responses to environmental challenges, highlighting the significance of gills in understanding both biology and ecology.
