Researchers closely examined each photo, and took note of the chimps’ gray hair. Sets of photos for both subspecies included wild and captive chimps.
#Chimpanzee without hair series
To produce evidence that gray hair is not indicative of old age among chimps, the study’s authors gathered together a series of photographs of two chimpanzee subspecies. “Chimps reach this point where they’re just a little salt and peppery, but they’re never fully gray so you can’t use it as a marker to age them.” Gray matters for chimps candidate in the GW Department of Anthropology, in a release.
With chimps that’s really not the pattern we found at all,” explains lead study author Elizabeth Tapanes, a Ph.D. “With humans, the pattern is pretty linear, and it’s progressive. After that point the graying process appears to level off. Most chimpanzees see portions of their hair gray over time until they reach middle age. The amount and locations of discoloration, however, varies greatly from chimp to chimp. Patches and areas of gray hair are very common in chimpanzees. While these findings may sound fairly inconsequential at first, in actuality they challenge the significance of the gray phenotype among non-human beings. It’s also a sign, of course, that we’re getting older - and more are on the way. For chimpanzees, however, hair color doesn’t follow the same linear path. As scientists from The George Washington University explain, observing gray or silver hair on a chimpanzee doesn’t mean you’re looking at an old timer. Sleep: the Chimpanzee will power down after a preset amount of time without activity.WASHINGTON - Finding that first gray hair is a rite of passage for humans.Demo: runs through 2 or 3 random animations.Guard: Uses the vision and sound sensors to detect intruders around it, and reacts in response, either with a random animation or if a program has been entered.Program: Up to 20 distinct steps (movements and sounds) can be entered in an ordered sequence that will be stored and can be played back at a later time.Direct Control: responds to user commands.Reacts to sensory input, and performs autonomous actions.
Remote control or autonomous interactivity.Stereo sound sensors detect loud sounds.Touch sensors in his chin, head and ears.Infrared vision system: detects movement, tracks objects and reacts to human interaction.Mood dependent behavior: responds to stimuli with mood specific animations and sounds.Some of the Chimpanzee's notable features are:
#Chimpanzee without hair skin
As with other WowWee robots, the Chimpanzee can be operated in different modes in its case, the modes are Alive, Guard, Program, Demo and Sleep.Ī Popular Science article on Halloween decorating describes how one can remove the robot's skin to create a Terminator-like robot face. In attempting to make the Chimpanzee as realistic as possible, each strand of hair is rooted individually into the skin of the robot and the skin moves and is colored to match realistic skin tones, including veining. There is also an Alive Elvis manufactured. It also contains 9 sensors, including IR sensors in the eyes, touch sensors on the chin, top and rear of the head and sound and vibration sensors in the ear. It houses eight motors to mimic the facial expressions of a real chimp. Unlike WowWee's other robots, the Chimpanzee only consists of the head of a chimpanzee. The animatronic Chimpanzee is the first in WowWee Alive's product line. The Alive Chimpanzee is produced by WowWee Alive, a division of WowWee Ltd.
