brain processes used in telepathy make extensive use of both language and visual circuits in humans. In
the visual system this is known to correspond to the high demands of the active predator ecological niche.
The low genetic diversity of the kzin race may have facilitated the emergence of a telempathic sense due
to the high degree of correlation of thought and emotional processes between individuals. There is then a
natural evolutionary pathway toward making use of the processing power of both visual and language
brain circuits in order to extract increasingly detailed information from the telempathic sense. This
development can in turn havelocked in those brain circuits to the demands of telempathic processing. In
the visual cortex these effects may not be noticeable, since the visual cortex is also locked into processing
patterns that correspond to a verifiable external reality; however, there is no single "correct"
combinatorial language system, which leaves the language centers of the brain free to select any of an
infinite number of equally valid symbol systems.
This is the case in humans, and human languages drift and evolve rapidly. However, in kzinti we may
conjecture that the telempathic sense has effectively locked in the language centers to its (still poorly
understood) demands, which would go far toward explaining both kzin linguistic homogeneity and
telepathic prowess. As a side note, hallucinatory experiences are common in human telepathic adepts,
which may be due to the telempathic and other senses competing for the same brain processor resources.
Kzinti telepaths also suffer from numerous cognitive difficulties, and this may explain why telepathy
evolves rarely and is seldom a highly developed sense in any species despite its obvious evolutionary
advantages: Its cognitive costs simply outweigh its survival benefits. The largest exceptions to this rule, the
now extinct Slavers and the sessile Grogs, both show clearly the cognitive drawbacks of a highly
developed telempathic sense.
Kzinti share with humans the ability to form hierarchical mass societies, but they are orders of magnitude
less social. Any society can be seen as a series of opportunities to cooperate or compete, and in kzinti
the balance falls more heavily on competition than in human society. This fact imposes strict limits on the
forms of society that the kzinti can successfully use, and in fact we can see that kzinti culture shows much
less variation than human culture does in terms of structure. The reasons for this are complex, but
ultimately, for any evolved organism, the final measure of success is the number of offspring injected into
future generationsin relation to the number of offspring injected by competitors. There are two basic
strategies available to achieve this, and we may categorize species asK (named because the population
total is characterized byK, the carrying capacity of the environment) andr (named because the population
total is characterized byr, the reproductive rate).K species are characterized by a small number of large
offspring, long lifetimes with late maturity, and high levels of parental care. Typer species have a large
number of small offspring, short lifetimes with early maturity, and low or no parental care.
In species with sexual reproduction we see two strategies, individuals who produce a small number of
large gametes (females) and those who produce a large number of small gametes (males). This tendency
usually generalizes so that we see females invest a large amount to ensure the success of a small number
of offspring, and males invest a small amount in any given offspring in order to maximize the total number
of offspring. Since the child-bearing capacity of females is the ultimate limit on the reproductive potential
of any given generation, we usually see a situation in which males compete for females. In a species like
the Wunderland gagrumpher, males invest no parental care in their offspring, and as a result we see a
large sexual dimorphism, with males averaging five times the weight of a female and possessing
specialized neck dewlaps, which serve both as an intimidation mechanism in male/male conflicts and as a
sexually selected attractant to females. There are exceptions to this rule. In some bird species the male
and female form long-term pair bonds and there is very little (although not zero) mate competition. As a
result males and females are nearly identical in body plan and require an expert (or a con specific) to
