===Other life=== * In the [[Africa]]n [[locust]], [[nerve]] cells start in the abdomen but connect to the wing. This leads to unnecessary use of materials.<ref name="Jury" /> * Intricate reproductive devices in [[orchid]]s, apparently constructed from components commonly having different functions in other flowers. * The use by [[panda]]s of their enlarged [[sesamoid bone#Other animals|radial sesamoid bones]] in a manner similar to how other creatures use [[thumb]]s.<ref name="Jury" /> * The existence of unnecessary wings in flightless birds, e.g. ostriches.<ref>{{cite book |first=Ernst |last=Haeckel |author-link=Ernst Haeckel |year=1892 |url=https://archive.org/details/historycreation01schmgoog |title=The History of Creation |publisher=D. Appleton |location=Appleton, New York |page=[https://archive.org/details/historycreation01schmgoog/page/n354 326]}}</ref> * The enzyme [[RuBisCO]] has been described as a "notoriously inefficient" enzyme,<ref>{{cite journal |author=Spreitzer RJ, Salvucci ME |s2cid=9387705 |title=Rubisco: structure, regulatory interactions, and possibilities for a better enzyme |journal=Annu Rev Plant Biol |volume=53 |pages=449β75 |year=2002 |pmid=12221984 |doi=10.1146/annurev.arplant.53.100301.135233}}</ref> as it is [[enzyme inhibitor|inhibited]] by oxygen, has a very slow turnover and is not saturated at current levels of carbon dioxide in the atmosphere. The enzyme is inhibited as it is unable to distinguish between carbon dioxide and molecular oxygen, with oxygen acting as a [[competitive inhibition|competitive enzyme inhibitor]]. However, RuBisCO remains the key enzyme in [[carbon fixation]], and plants overcome its poor activity by having massive amounts of it inside their cells, making it the most abundant protein on Earth.<ref>{{cite journal |author=Ellis RJ |title=Biochemistry: Tackling unintelligent design |journal=Nature |volume=463 |issue=7278 |pages=164β5 |date=January 2010 |pmid=20075906 |doi=10.1038/463164a|bibcode=2010Natur.463..164E |s2cid=205052478 }}</ref> * Sturdy but heavy bones, suited for non-flight, occurring in animals like bats. Or, on the converse: unstable, light, hollow bones, suited for flight, occurring in birds like penguins and ostriches, which cannot fly. * Various [[vestigial]] body parts, like the femur and pelvis in whales (evolution indicates the ancestors of whales lived on land). * ''[[Turritopsis dohrnii]]'' and species of the genus ''[[Hydra (genus)|Hydra]]'' have [[biological immortality]], but most animals do not. * Many species have strong instincts to behave in response to a certain stimulus. Natural selection can leave animals behaving in detrimental ways when they encounter a [[supernormal stimulus]] - like a [[moth]] flying into a flame. * Plants are green and not black, as [[chlorophyll]] absorbs green light poorly, even though black plants would absorb more light energy. * [[Whale]]s and [[dolphin]]s breathe air, but live in the water, meaning they must swim to the surface frequently to breathe. * [[Albatross]]es cannot take off or land properly.
