Humans and other mammals, however, can synthesize only half of them.

Humans ( older than 18 months ) and other great apes, bottlenose dolphins, pigeons, and elephants have all been observed to pass this test.

Humans and the great apes display the menstrual cycle, whereas most other mammals are subject to an estrous cycle.

Humans are the dominant race, but other sentient beings abound.

Humans are dependent on parental help for a large portion of their lifespans comparative to other mammals.

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.

They know nothing of other intelligent beings in the universe until first encountering Humans and Pierson's Puppeteers in Fleet of Worlds.

* TMS-SD provides public outreach events to classrooms, libraries, museums and other organizations throughout the Southern California region with seven different multimedia programs: " Invasion from Earth-The Robotic Exploration of Mars "; " Mars Exploration Rovers-Year 4 "; " Mars on Earth-The Adventures of Space Pioneers in the Utah Desert "; " Mars on Earth-The Adventures of Space Pioneers in the Canadian Arctic: " Humans to Mars-How We'll Get There "; " A Close Look at Mars "; and " Mars in the Movies "

Humans are subject to nitrate toxicity, with infants being especially vulnerable to methemoglobinemia due to nitrate metabolizing triglycerides present at higher concentrations than at other stages of development.

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.

Humans can become seriously ill from eating oysters and other shellfish contaminated with red tide toxin.

Humans leap from one leg to the other while running.

In 2161, Humans, along with Vulcans and several other species, founded the United Federation of Planets, which continued this wary peace.

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

Humans and other animals have developed senses that enable them to evaluate the potability of water by avoiding water that is too salty or putrid.

Humans can also spread the bacteria to other humans through sneezing, coughing, or direct contact with infected tissue.

Humans have developed many specialized methods for laundering, ranging from early methods of pounding clothes against rocks in running streams, to the latest in electronic washing machines and dry cleaning ( dissolving dirt in solvents other than water ).

** On the other hand, in the Crusade episode Visitors From Down the Street, Captain Matthew Gideon would launch a full spread of modified probes ( uploaded with considerable information about Earth and other Interstellar Alliance worlds, and about certain recent events which had transpired aboard the EAS Excalibur ) at a pre-hyperspace planet where Humans had been cast ( by the local government ) in a role reminiscent of the Grey Aliens in our culture, in order to expose the locals to the truth.

Humans have three different types of cones ( trichromatic vision ) while most other mammals lack cones with red sensitive pigment and therefore have poorer ( dichromatic ) color vision.

Humans, as well as some other organisms, can have a chromosomal arrangement that is contrary to their phenotypic sex, that is, XX males or XY females.

Humans who migrate permanently to a higher altitude naturally acclimatize to their new environment by developing an increase in the number of red blood cells to increase the oxygen carrying capacity of the blood, in order to compensate for lower levels of oxygen in the air.

In the Star Trek: The Next Generation episode " Hide and Q ", Q states to Commander Riker that the Human desire to explore and to learn, as well as their curiosity, will eventually lead Humans to a higher state of being.

There are currently six races in the world of Lineage II: the Humans, who are similar to modern-day humans and who have all-around balanced characteristics ; the Elves, who have superior dexterity, movement, and casting speed, but weaker offense ; Dark Elves, who have higher magic and melee attack capabilities ; Orcs, who have higher HP and MP but slower movement ; Dwarves, who are powerful melee attackers and master craftsmen ; and Kamael, who are humanoids with single wings and gender-specific job classes.

Humans are the primary host of the virus, but it also circulates in nonhuman primates.

Humans and closely related primates normally have three types of cone cells and are therefore trichromats ( animals with three different cones ).

Humans and closely related primates are usually trichromats, as are some of the females of most species of New World monkeys, and both male and female howler monkeys.

Humans are very similar to other primates in their propensity towards intra-species violence ; Jared Diamond's The Third Chimpanzee ( ISBN 0-09-980180-9 ) estimates that 64 % of hunter-gather societies engage in warfare every two years.

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 selectively bred them to enhance specific characteristics, such as color and length or body size.

Humans are the only ape in which the female is fertile year round, and in which no special signals of fertility are produced by the body ( such as genital swelling during estrus ).

Humans with natural eye lenses removed, as well as many animals with eyes that do not require lenses ( such as insects and shrimp ) are able to directly detect ultraviolet visually, by quantum photon-absorption mechanisms, in much the same chemical way that normal humans detect visible light.

Humans are capable of using the Web to carry out tasks such as finding the Irish word for " folder ", reserving a library book, and searching for the lowest price for a DVD.

Vulcans can perform mind melds with members of most other species, most notably Humans, with Jonathan Archer being the first known Human participant in such a ritual in 2154.

In 1957, the launch of Sputnik I, Earth's first artificial satellite, was observed by a Vulcan vessel that subsequently crashed on the planet, marooning several crew members for a number of months in Carbon Creek, Pennsylvania ; this constituted the first true contact between Humans and Vulcans, but it was never recorded as such as the Humans were unaware of the alien nature of their guests.

It is explained that after first contact, Vulcan shared technology with Earth, but many Humans, such as Jonathan Archer, greatly resented the fact that Vulcans seemed to be holding back humanity's efforts at space travel.

Humans even use other predatory species, ( such as dogs, cormorants, and falcons ) in hunting and fishing ; some people even enlist such non-predatory beasts, like horses, camels, and elephants in getting approaches to prey.

Humans also lack innate weaponry such as claws.

Humans share aspects of aggression with non-human animals, and have specific aspects and complexity related to factors such as genetics, early development, social learning and flexibility, culture and morals.

Humans have brought these populations under their control and care for a wide range of reasons: to produce food or valuable commodities ( such as wool, cotton, or silk ), for help with various types of work ( such as transportation, protection, and warfare ), scientific research, or simply to enjoy as companions or ornaments.

Humans would no longer be innately averse to incest, but would rely on their capacity to internalize such rules from cultural practices.

Humans need to feel a sense of belonging and acceptance, whether it comes from a large social group, such as clubs, office culture, religious groups, professional organizations, sports teams, gangs, or small social connections ( family members, intimate partners, mentors, close colleagues, confidants ).

Humans were thought to possess divine powers such as reason, love, and imagination.

Humans, however, were capable of both intellectual sin and physical sins such as lust and gluttony if they let their animal appetites overrule their divine reason.

Humans are the driving force behind urban ecology and influence the environment in a variety of ways, such as modifying land surfaces and waterways, introducing foreign species, and altering biogeochemical cycles.

Humans are also vulnerable to panic and it is often considered infectious, in the sense one person's panic may easily spread to other people nearby and soon the entire group acts irrationally, but people also have the ability to prevent and / or control their own and others ' panic by disciplined thinking or training ( such as disaster drills ).

Humans have encountered eight of the larger Motie subspecies, not including hybrids such as the Mediators: Masters, Engineers, Doctors, Porters, Farmers, Runners, Watchmakers and Meats, but the Masters concealed the existence of another type-the Warriors.

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.
