Ginkgo is a monotypic genus of highly unusual non-flowering plants. The scientific name is also used as the English name. The order to which it belongs, Ginkgoales, first appeared in the Permian,[4] 270 million years ago, possibly derived from “seed ferns” of the order Peltaspermales, and now only contains this single genus and species. The rate of evolution within the genus has been slow, and almost all its species had become extinct by the end of the Pliocene; the exception is the sole living species, Ginkgo biloba, which is only found in the wild in China, but is cultivated across the world. The relationships between ginkgos and other groups of plants are not fully resolved.

Psocoptera are an order of insects that are commonly known as booklice, barklice or barkflies.[1] They first appeared in the Permian period, 295–248 million years ago. They are often regarded as the most primitive of the hemipteroids.[2] Their name originates from the Greek word ψῶχος, psokhosmeaning gnawed or rubbed and πτερά, ptera meaning wings.[3] There are more than 5,500 species in 41 families in three suborders. Many of these species have only been described in recent years.[4]

Attitudes towards different hair, such as hairstyles and hair removal, vary widely across different cultures and historical periods, but it is often used to indicate a person’s personal beliefs or social position, such as their age, sex, or religion.[1]
A beard is the collection of hair that grows on the chin and cheeks of humans and some non-human animals. In humans, usually only pubescent or adult males are able to grow beards. From an evolutionary viewpoint the beard is a part of the broader category of androgenic hair. It is a vestigial trait from a time when humans had hair on their face and entire body like the hair on gorillas. The evolutionary loss of hair is pronounced in some populations such as indigenous Americans and some east Asian populations, who have less facial hair, whereas people of European or South Asian ancestry and the Ainu have more facial hair. Women with hirsutism, a hormonal condition of increased hairiness, may develop a beard.
