| The rules that govern
our mating behaviors are instinctive and deeply rooted. In a number of
mammalian species, when males reach middle age they respond to a biological
realization that they are no longer in their prime. These aging silverbacks
can no longer compete physically or sexually with the upcoming group of
younger males, and in a biological panic, their reproductive urges trigger
them to make one last fling at mating with younger, more fertile females.
In humans, this manifests itself when a middle-aged man suddenly feels
the urge to display his wealth by buying a fancy sport car, begins ignoring
his wife and starts a workout routine. This middle age crisis is simply
one example of our response to animal programming.
Fortunately, we humans have
the ability to control our own behaviors and are not complete slaves to
these drives. Still, it is useful to understand our passions in the light
of these powerful animal urges.
Thus,
when
a wildcat and a fox get together, they share a common range
and nocturnal spirit. However, as a canine, the fox is a natural competitor
of the cat and its natural friendliness grates against the cat's tendency
to maintain its distance. Over time, these tensions conspire to destroy
the relationship. Likewise, if a mouse personality married a cat,
power conflicts or spousal abuse can quickly destroy the union. So, all
animal personalities should avoid forming close relationships with their
species' natural predator.
However, this does not mean
that all herbivorous personalities must avoid predators. The meek
cottontail might even strike up
a friendship with a powerful lion, since lions are disinclined to
waste energy chasing elusive, low calorie rabbits. Although marriage
is out of the question, these friendships can be quite enduring. In exchange
for companionship and loyalty, the predator provides resources and protection
for the cottontail.
Animal personalities tend
to relate to species that share their ranges. The water personality of
the dolphin has much in common
with the aquatic sea lion and the pastoral nature of the sheep
makes for a compatible mate with the grazing deer.
Conversely, animal personalities
that live in markedly different environments tend to avoid each other.
Birds choose to remain out of reach of the land mammal personalities
and the unencumbered lives of the sea dwellers make them awkward mates
for complex land creatures. On the other hand, the semi-aquatic beaver
is capable of forming relationships with both sea-going and land-based
animal personalities.
