Common Vandal - Homo sapiens stupidus
A sub species of Homo sapiens, they are rarely spotted during daylight hours, as most are nocturnal, preferring the dark to cover their activities. A genus of mostly similar habits to H. sapiens they have evolved a trait of destroying or defacing their habitat through boredom and lack of stimulation. Mostly a timid mammal, usually males ♂ although females ♀ are occasionally found, they will attempt to hide when confronted by the appearance of H. sapiens. However some can be aggressive, becoming violent when found in the act of performing, which is a condition called 'vandalism'. The effects of H. sapiens stupidus can be varied and far reaching, they are locally common throughout the planet, but in some localities they can be quite rare. Colouration many and varied, feeding habits vary with some individuals being herbivores. Drinking habits are more probably habit / ritual based with many of the species preferring alcohol based fluids from containers that are then left in the area where they are performing, possibly as decoration for the 'vandalism' ritual.
Several of the species have been found performing in Brickfields Park over the years, mostly the juvenile form before they become adult, tending to rip branches from trees. A small group was found late one evening having just finished a 'performance' using paint to decorate rocks. A passive group, they were rounded up and taken to the local authorities for evaluation and released back into the wild a few hours later. The breeding habits of H. sapiens stupidus has not been verified, although the differing ratio of males ♂ to females ♀ cast doubt on the species viability, however there is some thought that the species can interbreed with H. sapiens forming regressive hybrids that reappear in later generations.
On the rare occasion that H. stupidus. has been encountered during the day it can be capable of limited discussion about it's lifestyle, other subjects can be touched on but are usually limited to being "bored". Suggesting alternative forms of pastime or even (horror of horrors) WORK, elicits a shoulder shrug gesture, taken to mean "I don't know" or "I don't care", occasionally accompanied with "F@*$ off", a universal phrase used to convey - abuse / no / yes / goodbye - and several other meanings not yet ascertained by linguists.
