3 days ago · Possible early ancestors of catarrhines include Aegyptopithecus and Saadanius. 35-20 Ma Proconsul. Catarrhini splits into 2 superfamilies, Old World monkeys (Cercopithecoidea) and apes . Human trichromatic color vision had its genetic origins in this period. Catarrhines lost the vomeronasal organ (or possibly reduced it to vestigial status).
3 days ago · Early in Earth's history, photosynthetic life first appeared and it is most likely that these first forms were anoxygenic (non-oxygen evolving). The enzymatic and energetic foundations of life underwent a radical change when oxygenic photosynthesis was developed and atmospheric oxygen levels rose, about 2.4 billion years ago.
6 days ago · The vast majority of biological carbon sequestration occurs via photosynthesis, which first arose between three and four billion years ago [25]. Photosynthesis is a biochemical process involving the use of light radiation (typically in the wavelength range of 400–700 nm) to reduce CO2 into. Earth.
2 days ago · In the Early Miocene, about 22 million years ago, the many kinds of arboreally-adapted (tree-dwelling) primitive catarrhines from East Africa suggest a long history of prior diversification. Fossils at 20 million years ago include fragments attributed to Victoriapithecus, the earliest Old World monkey.
4 days ago · Fossils of plants from the early Devonian show that a simple form of wood first appeared at least 400 million years ago, at a time when all land plants were small and herbaceous. Because wood evolved long before shrubs and trees, it is likely that its original purpose was for water transport, and that it was only used for mechanical support later.
4 days ago · Lemurs (suborder Strepsirrhini). primate, in zoology, any mammal of the group that includes the lemurs, lorises, tarsiers, monkeys, apes, and humans. The order Primates, including more than 500 species, is the third most diverse order of mammals, after rodents (Rodentia) and bats (Chiroptera). Although there are some notable variations between ...

2 days ago · Dr Pellicer, a researcher in evolutionary biology, says: “Tmesipteris is a unique and fascinating small genus of ferns, whose ancestors evolved about 350 million years ago – well before dinosaurs set foot on Earth – and it is distinguished by its mainly epiphytic habit [it grows mainly on the trunks and branches of trees] and restricted ...
