The convex cornea and the convex crystalline lens of the human eye produce focused, real images which are inverted vertically and horizontally, because light rays cross over at the focal point of the combined cornea and lens. The primate visual field is determined by the frontality of the eyes, by the protuberance of the eyes,…

Right-handedness.
bilateral control, Cerebellar hemispheric activation ipsilateral to the paretic hand correlates with functional recovery after stroke, cerebellar reserve, dextrality, dominance, Evidence of increased cardiovascular disease risk in left-handed individuals, Finger and Face Representations in the Ipsilateral Precentral Motor Areas in Humans, ipsilateral motor control, lagophthalmos, lateralization, left-handedness, neuroplasticity, Orrorin tugenensis, premotor activation, right-handedness, sinistralityHumans are predominantly right-handed because of the position of the heart: left-handedness carries an increased risk of cardiovascular disease. The heart was tilted to the left of the sternum in bipedal primates. The human right hand is controlled by the left cerebral hemisphere and by the right cerebellar hemisphere, which bilateral control means that in…

The vectorial analysis used in evolutionary game theory is simplistic, because communications between humans have both magnitude and direction, and can occur at multiple levels simultaneously. The study of evolutionary game theory is predominantly a male activity that predicts a reduced expectation of life, that shifts focus from the present to the future, and that…

Phonolocation is the use of laryngeal sounds to locate oneself in the world. Throat clearances and coughs signal one’s attentive presence, and any response indicates the likelihood of immediate contact with the responder. Phonolocation, forced sneezes, face masks and nose picking, that is rhinotillexis, can be used to keep philistinism and pseudo-conversation at a distance.

Batesian mimicry has been said to be parasitic, while Müllerian mimicry has been said to be mutualistic. But the Batesian model benefits from the presence of the mimic, give the lesser likelihood of an attack on the model, and Müllerian mimics may be defended to different degrees, so that one mimic may be relatively dependent…

Blushing occurs when one is embarrassed.Blushing is more common in the young than in the old, and in women compared with men. Blushing is due to dilatation of blood vessels in the face, transmitted through the sphenopalatine ganglia by parasympathetic nerves, which indicates that blushing occurs when one feels safe. Blushing signals that one cares…

The debate about altruism lacks adult judgements. Any supposedly altruistic response should be judged by the latency of the response, by the number of bystanders, by the genetic relatedness between the altruist and the beneficiary, and by the amount of social contact between the altruist and the beneficiary and between the altruist and any bystander,…

Humans cooperate because they remember their own fallibility, which is why cooperation increases with age.
To be or not to be.
