These are 3 species that people know very little about or they know nothing. The information are confirmed by scientists, who still research to find out more about them.
These may be either unicellular or pluricellular organisms; they do not have superior specialized tissues. In the phylogenetic tree of eukaryotic organisms, the antiscites formed separate monopile groups, or included members that are closely related to any of the other four eukaryotic regiments.
- Tapanuli Orangutan
Until now, the orangutans were classified as being part of two distinct species reflecting their geographical spread: Borneo orangutan (Pongo pygmaeus) and Sumatra urangutan (Pongo abelii). The new species, called Tapanuli orangutan (Pongo tapanuliensis), lives in the Batang Toru area of North Sumatra and has an estimated 800 members. This new species is as old as the earliest species of our direct ancestors. The new discovery, made by scientists, comes to the conclusion that there are less than 7,000 Sumatra orangutans at large. Like the other species of orangutan, the Tapanuli group is also threatened by poaching and habitat destruction.
- Marsupial Lion
A newly discovered species of marsupial lion, whose representatives had the size of some cats and disappeared from the Earth at least 18 million years ago, was named after the famous British naturalist David Attenborough. So far, information about Thylacoleo carnifex or marsupial lion was controversial. Over time, there have been theories of lion marsupial that they would be fed by eggs crocodile that had been saprofag, just like hyenas or predators as fearsome as the leopard, who led prey from above, in the tree. Scientists at Adelaide University say this animal lived in trees. Its lower limbs were extremely strong, specific to the animals that climb. Members of this species, now gone, were very good climbers and raised their cubs in caves.
