One study based on DNA analysis suggests that Scandentia and Primates are sister clades, but does not discuss the position of Dermoptera. [9] Although it is known that Scandentia is one of the most basal Euarchontoglires clades, the exact phylogenetic position is not yet considered resolved, and it may be a sister of Glires, Primatomorpha or Dermoptera or to all other Euarchontoglires.

In biology and genetic genealogy, the most recent common ancestor (MRCA), also known as the last common ancestor (LCA), of a set of organisms is the most recent individual from which all the organisms of the set are descended. The term is also used in reference to the ancestry of groups of genes rather than organisms.
Molecular studies by molecular systematists, based on DNA analysis, in the early 21st century have revealed new relationships among mammal families. Classification systems based on molecular studies reveal three major groups or lineages of placental mammals, Afrotheria, Xenarthra, and Boreoeutheria. which diverged from early common ancestors in the Cretaceous.
The Croods gave moviegoers a comedic animated view of some of our human ancestors and the wild world they might have inhabited during the Pliocene epoch. In the sequel, The Croods: A New Age, our ...
Common threats to primate species include deforestation, forest fragmentation, monkey drives (resulting from primate crop raiding), [220] and primate hunting for use in medicines, as pets, and for food. Large-scale tropical forest clearing is widely regarded as the process that most threatens primates.
Common descent is a concept in evolutionary biology applicable when one species is the ancestor of two or more species later in time. According to modern evolutionary biology, all living beings could be descendants of a unique ancestor commonly referred to as the last universal common ancestor (LUCA) of all life on Earth .
The last common ancestor is the vertical line stem at the bottom. The blue and orange subgroups are clades; each shows its common ancestor stem at the bottom of the subgroup branch . The green subgroup alone does not count as a clade; it is a paraphyletic group with respect to the blue group, because it excludes the blue branch which has ...
