what is missing link in biology

[27] It is one of several lines of ancient sarcopterygians to develop adaptations to the oxygen-poor shallow water habitats of its time—adaptations that led to the evolution of tetrapods. It is most commonly used to refer to any new transitional fossil finds. The term "missing link" has been used extensively in popular writings on human evolution to refer to a perceived gap in the hominid evolutionary record. [48], The term "missing link" refers back to the originally static pre-evolutionary concept of the great chain of being, a deist idea that all existence is linked, from the lowest dirt, through the living kingdoms to angels and finally to God. [36], A Middle Devonian precursor to seed plants has been identified from Belgium, predating the earliest seed plants by about 20 million years. Like all modern tetrapods, it had rib bones, a mobile neck with a separate pectoral girdle, and lungs, though it had the gills, scales, and fins of a fish. No one has yet identified what the direct successor of Eucritta was, though whatever the identity of this genuine missing link, it probably counted as one of the first true amphibians. [6] Transitional forms are seen as falling between the various groups in terms of anatomy, having a mixture of characteristics from inside and outside the newly branched clade. “We know almost nothing about what sort of microbial life exists in the world around us, and so the vast majority of diversity has been invisible,” said Banfield. Present in plants, cyanobacteria (also known as blue-green algae) and other photosynthetic organisms, it’s central to the process of carbon fixation and is one of Earth’s oldest carbon-fixing enzymes.
