For example, the basal ganglia (structures derived from the floor of the forebrain and making up MacLean's reptilian complex) were shown to take up a much smaller portion of the forebrains of reptiles and birds (together called sauropsids) than previously supposed, and to exist in amphibians and fish as well as mammals and sauropsids. Because ...
The tissue that the human brain is made up of decomposes once the organism has died, so old brain tissue cannot be analysed, [9] however, due to the large percentage that the neomammalian brain takes up in the human brain, estimated to be 76%, [5] comparative anatomy shows that the Homo sapiens has a much larger cranial size than early primate ...
[7] [8] The idea of reptilians was popularised by David Icke, a conspiracy theorist who claims shapeshifting reptilian aliens control Earth by taking on human form and gaining political power to manipulate human societies. Icke has stated on multiple occasions that many world leaders were, or are possessed by, so-called reptilians.
Young human and non-human animals without neocortices retain these brain-mind functions. Furthermore, neural circuits supporting behavioral/electrophysiological states of attentiveness, sleep and decision making appear to have arisen in evolution as early as the invertebrate radiation, being evident in insects and cephalopod mollusks (e.g ...
A method used to test ToM in human children has been adapted for testing non-human animals. The basis of the test is to track the gaze of the animal. One human hides an object in view of a second human who then leaves the room. The object is then removed. [14]
Human domestication of wild plants began about 11,700 years ago, leading to the development of agriculture, [233] a gradual process called the Neolithic Revolution. [234] These dietary changes may also have altered human biology; the spread of dairy farming provided a new and rich source of food, leading to the evolution of the ability to ...
In South Asian and Southeast Asian mythology, the Nāga are semi-divine creatures which are half-human and half-snakes. [1] Claims of sightings of reptilian creatures occur in Southern United States, where swamps are common. In the late 1980s, there were hundreds of supposed sightings of a "Lizard Man" in Bishopville, South Carolina. [2]
The major reptile group Diapsida, for example, is defined by the presence of two temporal fenestrae on each side of the skull. The infratemporal fenestra , also called the lateral temporal fenestra or lower temporal fenestra , is the lower of the two and is exposed primarily in lateral (side) view.
