A living fossil is a deprecated term for an extant taxon that phenotypically resembles related species known only from the fossil record. To be considered a living fossil, the fossil species must be old relative to the time of origin of the extant clade. Living fossils commonly are of species-poor lineages, but they need not be.
The 2024 UNEP Food Waste Index Report, "Think Eat Save: Tracking Progress to Halve Global Food Waste," addresses the severe issue of food waste that accounts for US$1 trillion in losses, 8–10% of global greenhouse emissions, and the unnecessary use of 30% of the world's agricultural land, exacerbating hunger and affecting child growth.
Fruits and vegetables are living parts of a plant and contain 65 to 95 percent water. When food and water reserves are exhausted, produce dies and decays. Anything that increases the rate at which a product's food and water reserves are used up increases the likelihood of losses.
The ginkgo (Ginkgo biloba) is a living fossil, with fossils similar to the modern plant dating back to the Permian, 270 million years ago.The closest living relatives of the clade are the cycads, [4] which share with the extant G. biloba the characteristic of motile sperm.
A life form (also spelled life-form or lifeform) is an entity that is living, [1] [2] such as plants , animals , and fungi . It is estimated that more than 99% of all species that ever existed on Earth, amounting to over five billion species, [3] are extinct. [4] [5] Earth is the only celestial body known to harbor life forms. No form of ...
The coelacanth was long considered a "living fossil" because scientists thought it was the sole remaining member of a taxon otherwise known only from fossils, with no close relatives alive, [8] and that it evolved into roughly its current form approximately 400 million years ago. [1]
The production of all this food also results in more and more agricultural waste. In large quantities, agricultural waste can have a negative impact on the environment and habitat, for example through greenhouse gas emissions, the creation of unpleasant odours, and toxic liquids that can infiltrate water sources.

Paleobotany, also spelled as palaeobotany, is the branch of botany dealing with the recovery and identification of plant remains from geological contexts, and their use for the biological reconstruction of past environments (paleogeography), and the evolutionary history of plants, with a bearing upon the evolution of life in general.
