proboscis   a tissue extending from the front of the face which evolved as a mechanism to probe the space ahead, a bit like a blind person’s cane, or the front bumper of a car. If an animal walked slowly enough and hit an obstacle, it would first detect the impact via the proboscis, which is composed of tissue soft enough to absorb the impact providing the animal is not traveling faster than about 10 cm per second. Upon encountering an obstacle, sensors in the proboscis trigger a reflex that instinctively brakes the rest of the body before it suffers so much damage that insurance companies need to get involved. In many mammalian species this function became redundant through the evolution of whiskers, which is why the species with the longest whiskers tend to have the smallest noses (felines), and vice versa (elephants, whose tiny whiskers are purely ornamental). Derivatives include proboscuity, a habitual and socially offensive behavior in which the proboscis is inserted into places, situations or affairs where it has no business being.

alignment  placing two things next to each other in a way that lines up their ends, at which point they will be determined to have equal length or not. If not, the problem generally needs to be corrected. If aligning one end causes the other not to align, the standard procedure is to chop off the longer one to achieve double-ended alignment. If you cut off too much then the other item will now be the longer one and you must now repeat the operation on the second item, being careful not to get them confused. It is considered aesthetic to align hair, for example, on opposing sides of a person’s head to achieve a symmetrical result, but the actual process of ensuring that each hair on the left side aligns with its partner hair on the right is so complex that it must generally be done by experts and costs about $400. Amateurs often misalign the two sides numerous times in succession, which is the major cause of baldness. This can be avoided by placing a bowl on the head of the person you are trying to align, checking to ensure that their spine and head are straight through the use of a leveling device, and then cropping the hair evenly around the rim of the bowl. The bowl itself, of course, must be perfectly symmetrical and balanced at the exact zenith of the head, preferably by fixing it into place with a small nail or powerful adhesive so that slippage does not occur.

In genetics the term refers to aligning the genomes of two species to determine which one has “the longer one.” Anything hanging over is probably responsible for features found in one species but not the other. It is a myth that females tend to choose mates with extra letters that extend the length of their genomes. Technique is just as important.

conditioning  any process of training which causes a biological entity, such as your hair, to behave the way you want it to rather than to follow its natural instincts.

diuretic  a substance produced by plants which, when ingested by an animal, causes it to release the water it has taken up from the environment more quickly, and closer to its source, rather than carrying it long distances away and depositing it in a foreign watershed. This phenomenon means that diuretic plants get more water and have an advantage in natural selection. A high number of non-diuretic plants in a particular environment usually triggers the rapid development of deserts: the water needed by the plants is carried too far away to do them any good. Upon the death of such plants, the organisms that eat them migrate away, further reducing the recycling of water. The effect is self-reinforcing, which ultimately causes animals to cluster along coastlines, resulting in a huge spike in real estate prices and making a species susceptible to extinction by tsunami. Over the long term this cycle leads to environmental conditions like those found on the moon and Mars, which could have been prevented by the evolution of a single plant with diuretic properties.

generation time  the period of time that a mother requires between giving birth to one child or litter and the next. Mathematically the generation time for a species can be calculated using the following formula:

gestation time + x

where gestation is the amount of time between conception and birth and x is the amount of time between giving birth and the resumption of sexual activity by the mother, usually due to the insistent behavior of her partner.

For humans this generally results in a generation time of 9 months + 20 minutes

habituation  the process by which the brain becomes desensitized to sounds, smells, advertising, well-meaning advice from family members, and various other annoying stimuli rather than responding in an instinctual way, for example by becoming an ax murderer.

mammary gland  what you say to your mother if it becomes necessary to refer to her boob.
