Humans have evolved to mentally represent numbers in two major ways from observation ( not formal math ).

Humans and other mammals have evolved trichromacy based partly on pigments inherited from early vertebrates.

Humans are thought to have evolved with a diet of a 1-to-1 ratio of omega-6 to omega-3 and the optimal ratio is thought to be 4 to 1 or lower, and it is even better if there is more omega − 3 than omega − 6 ( especially healthy ratio of omega − 6 to omega − 3 is from 1: 1 to 1: 4 ).

The 1978 Cylons were the machine soldiers of a reptilian alien race, while the 2003 Cylons were the former machine servants of humanity who evolved into near perfect humanoid imitation of Humans down to the cellular level, capable of emotions, reasoning, and sexual reproduction with Humans and each other.

Humans have evolved to maintain spatial orientation on the ground.

( The Deconstruction of Falling Stars ) Humans, now evolved into energy beings, have left Earth for the last time, and are capable of assuming physical form.

According to Susan Greenfield the practice is " nonsense " from a neuroscientific point of view: " Humans have evolved to build a picture of the world through our senses working in unison, exploiting the immense interconnectivity that exists in the brain.

Humans evolved to live as simple hunter-gatherers in small tribal bands, a very different way of life and environment than that faced by contemporary humans.

Humans and most eukaryotes have evolved an ACC with CT and BC catalytic domains and biotin carboxyl carrier domains on a single polypeptide.

The basic game setting was an area known as " The Frontier Sector " where four sentient races ( Dralasite, Humans, Vrusk, and Yazirian ) had met and formed the United Planetary Federation ( UPF ).

Humans compete usually for food and mates, though when these needs are met deep rivalries often arise over the pursuit of wealth, prestige, and fame.

** In the Star Trek: Enterprise episodes " Demons " and " Terra Prime " ( both 2005 ) it is revealed that Mars is in the process of being terraformed by use of the Verteron array which redirects comets to crashland on the planet's surface ; by 2155 the atmosphere had been sufficiently altered so that, in the lowlands, Humans could breathe the air unassisted, though temperatures were still cold enough to require thermal gear.

Humans are sensitive to cold, see hypothermia.

In the time of Star Trek: Enterprise, Vulcans are often seen to be rather arrogant and cold in their behavior towards Humans.

Humans are also attacked if they approach a nest too closely, with the aggressive male having torn clothes and drawn blood in such cases.

Humans bear responsibility for all situations they are in, and in the way they act to one another.

Humans first seek to ensure survival, and then they seek to dominate.

Humans recognise that they possess both actual and potential selves.

Humans acquire language through social interaction in early childhood, and children generally speak fluently when they are around three years old.

Humans and other mammals have a dietary requirement for certain essential fatty acids, such as linoleic acid ( an omega-6 fatty acid ) and alpha-linolenic acid ( an omega-3 fatty acid ) because they cannot be synthesized from simple precursors in the diet.

Humans are capable of discerning the difference between good and evil because they have a conscience.

Humans and other animals have amylases, so they can digest starches.

Humans and many other animals lack an enzyme to break the beta-linkages, so they do not digest cellulose.

The original homeworlds of the Dralasites, Humans, and Vrusk were never detailed in the setting and it is possible that they no longer existed.

Humans can manage not to injure themselves excessively when dealing with barbed wire as long as they are cautious.

< http :// www. theglaringfacts. com / erich-fromm-humanistic-psychoanalysis />.</ ref > Humans can destroy through malignant aggression, or killing for reasons other than survival, but they can also create and care about their creations.

Humans also engage in mutualisms with other species, including their gut flora ( without which they would not be able to digest food efficiently ).

Contrary to the Vulcan image of expressing no emotion, family bonds can be strong and affectionate just as they are for Humans.

( Technically speaking, these three events occurred after the founding of the Federation, but are included here as they constitute pre-First Contact encounters with contemporary Humans.

Humans are not rational by definition, but they can think and behave rationally or not, depending on whether they apply, explicitly or implicitly, the strategy of theoretical and practical rationality to the thoughts they accept and to the actions they perform.

Humans and penguins are bipedal, and so are then in the orange circle, but since they cannot fly they appear in the left part of the orange circle, where it does not overlap with the blue circle.

Humans may also attempt to conceal aspects of their own self which they are not capable of incorporating psychologically into their conscious being.

Humans, like other mammals, are diphyodont, meaning that they develop two sets of teeth.

Humans have developed some of these polysaccharides into useful products, including xanthan gum, dextran, welan gum, gellan gum, diutan gum and pullulan.

Humans possess a number of paranasal sinuses, divided into subgroups that are named according to the bones within which the sinuses lie:

Humans have introduced pigs into Australia, North and South America, and numerous islands, either accidentally as escaped domestic pigs which have gone feral, or as wild boar.

Thus, Humans were divided into linguistic groups, and unable to understand each other.

However, Ferengi often see other races as self-righteous and, as Ferengi have come into regular contact with Humans, their own self-image has improved by comparison.

Humans frequently translate actual objects into culturally conceived forms, an example being the translation by the Duna of the pig into an item of compensation and redemption.

It is presented in a myth-like fashion, detailing a building project by Dwarves and Men which is cursed by a mysterious stranger, resulting in a warpstone shower which mutates the rats of the city, and new-born Humans, into Skaven.

Humans can perceive the number of members in a small set without actually counting them or mentally breaking them into subsets ; the upper limit of this ability is estimated at between 5 and 9 units, and this seems to hold true in sequences of audible stimuli ( e. g. syllables in a line of verse ); so it is no surprise that syllabic hemistichs tend to be very short ( typically 4 to 8 syllables ), and to be grouped — and therefore separated from their neighbors — by markers such as stress, word boundary, and rhyme.

Humans have strong muscles in the legs and would need swim fins ( like a frog ) to bring all their power into the water and stand with the sole of the feet on the water.

Humans are stolen by malicious or inscrutable faerie lords, transformed into fae creatures, and then escaped back to our world.

Humans in the setting have also attempted to use psychohistory, but with less skill or success ; the Psionic Suppressions ( which turned public opinion within the human Imperium against those with paranormal mental abilities, forcing them to go into hiding ) resulted, unknown to most, from an experiment in psychohistory that got out of control and went much farther than the experimenters intended.

After the human colony leader starts bombing the octospider city under a made-up pretext and the octospiders retaliate, the situation becomes dire enough that Rama's controlling intelligence intervenes to end the conflict caused by the Humans aboard, by sending everybody into hibernation until the end of the journey.

Humans are seen as spirits attending the school of life for the purpose of unfolding latent spiritual power, developing themselves from impotence to omnipotence ( related also to development from innocence into virtue ), reaching the stage of creative gods at the end of mankind's present evolution: Great Day of Manifestation.

In the Star Trek: The Next Generation episode " The Chase ", Picard's archeology professor Galen, postulates and later proves the existence of a Proto-Humanoid race, which seeded the Milky Way Galaxy's class-M worlds with its genetic code, producing a tendency for sentients to develop into humanoid form, presumably including Humans.

Empathy combined with love could be the very thing that unifies Humans into helping others.

Minbari believe in a form of reincarnation, where the souls of each generation are reborn into the next ; faced with a human with a Minbari soul, the council concluded that Minbari souls were being reborn in Humans.
