The 1 percent difference:
Humans are distinct from chimpanzees in a number of important respects,
despite sharing nearly 99 percent of their DNA.
New analyses are revealing which parts of the genome set our species apart...

human condition is such that
pain and effort are not just symptoms
 which can be removed without changing life itself;

they are the modes in which life itself,
together with the necessity to which it is bound,
makes itself felt.

For mortals, the ‘easy life of the gods'
would be a lifeless life.”

– Hannah Arendt (October 14, 1906 – December 4, 1975)
was an influential German-Jewish political theorist. She has often been described as a philosopher, although she refused that label on the grounds that philosophy is concerned with "man in the singular." She described herself instead as a political theorist because her work centers on the fact that "men, not Man, live on the earth and inhabit the world."
Arendt's work deals with the nature of power, and the subjects of politics, authority, and totalitarianism. Much of her work focuses on affirming a conception of freedom which is synonymous with collective political action among equals...Commemoration honouring Hannah: You can read more about Hannah Arendt by clicking here
Only human beings are known to ask themselves questions relating to the purpose of life beyond the base need for survival, or the nature of existence beyond that which is empirically apparent:

-   What is the meaning of existence?
-   Why was I born?
-   Why am I here?
-   Where will I go when I die?

The human struggle to find answers to these questions — and the very fact that we can conceive them and ask them — is what defines the
human condition in this sense of the term.....To learn more about the HUMAN CONDITION please click here

Along with "men"... living being that co-habit with "men".... and have powers "men" the supposedly "supreme species" do not yet have.... these powers as described below of gecko's tail that saves its owner life.... 

A tail that fakes

“A gecko's tail continues to flip, flop and wriggle long after it has dropped off the lizard's body,” Jennifer Viegas reports for the Discovery Channel.

“Now a new study proposes the tail is preprogrammed for random movement to foil predators while the rest of the gecko makes a speedy getaway. …

Researchers have discovered that geckos can sever their spinal cords near their tails to escape predators. The neurons in the tail control its movement even after it falls off the gecko — a finding that may help human with spinal cord injuries.

The study proposes the tail is preprogrammed for random movement to foil predators while the rest of the gecko makes a speedy getaway.

Since the secret appears to be neurons that can generate movement without direct instructions from the brain, future research could benefit humans and other animals that have sustained spinal cord injuries.

In the gecko's case, its tail is actually an extension of its spinal cord. No other animal, however, appears to be able to self-amputate a body part that can later move. It would be like a person dropping off one leg that continues to hop around while the rest of the person escapes.

"Other animals can lose appendages, such as spiders, sea stars and lobsters, but the purpose isn't to distract a predator like the lizard tail," lead author Timothy Higham told Discovery News, explaining that these other animals just have the still-remarkable ability to regenerate the lost body part.

They first anesthetized the reptiles in order to implant electrodes on various parts of the geckos' bodies. Once recovered, the geckos had their tails lightly pinched by the scientists, causing each lizard to release its tail through a series of muscle contractions.

"These muscular contractions cause the vertebra to break in half, and the tail falls off," Higham explained.

He and Russell next placed the tails in a filming arena. Using a high-speed video camera, they determined each tail continued to wriggle, as well as to lunge by pushing with its tip. The tails could flip up to 1.2 inches in height by themselves. The complex movements lasted for up to 30 minutes.

The study is published in the latest issue of the Royal Society journal Biology Letters.
PVAF is presenting today's news story to show how amazing is our Creator's creations and then the created "men" is now creating own creations competing with the Creator....all this as part of KNOWLEDGE sharing but also showing how little "men" know of the Creator's capability not only to create but also to self-sustain as in the case of isopod.....and then continually recreate so that life always evolves to progress and prosperity suiting the species of life....

Now click on the next line to continue reading about  the isopod, sea-dwelling parasite that eats a fish's tongue and then takes the tongue's place in the fish and also a robot created by "men" and controlled by human brain cells....


A tongue that bites

Cymothoa exigua or the Tongue eating louse.
This is the only known case of a parasite functionally replacing a host organ.

A rare, sea-dwelling parasite that eats a fish's tongue and then takes the tongue's place in the fish was discovered off the coast of Jersey in Europe, BBC reports.

The isopod is about 2.5 centimetres long and was first found by fishermen. “When we emptied the fish bag out there at the bottom was this incredibly ugly looking isopod,” marine researcher Paul Chambers told the BBC.

 “Really quite large, really quite hideous – if you turn it over it's got dozens of these really sharp, nasty claws underneath …” The fish, he said, doesn't experience “too much ill effect … except it's lost its tongue.”

Experts said there have been similar sightings that dated back to 1996.

The isopod doesn't bother humans, but don't try to touch it, Mr. Chambers advises. “They are vicious – they will deliver a good nip.”

Isopods are an order of peracarid crustaceans, including familiar animals such as woodlice and pill bugs. The name Isopoda derives from the Greek iso meaning "same" and pod meaning "foot". The fossil record of isopods dates back to the Carboniferous period (in the US Pennsylvanian epoch), at least 300 million years ago.

Isopods are relatively small crustaceans with seven pairs of legs, ranging in size from 300 micrometres (0.012 in) to nearly 50 centimetres (20 in) in the case of Bathynomus giganteus. They are typically flattened dorso-ventrally, although many species deviate from this plan, particularly those from the deep sea or from ground water.

Isopods lack an obvious carapace, which is reduced to a "cephalic shield" covering only the head. Gas exchange is carried out by specialized gill-like pleopods towards the rear of the animal's body.

In terrestrial isopods, these are often adapted into structures which resemble lungs, and these "lungs" are readily visible on the underside of a woodlouse. Eyes, when present, are always sessile, never on stalks.

They share with the Tanaidacea the fusion of the last abdominal body segment with the telson, forming a "pleotelson",[4] and the first body segment of the thorax is fused to the head. The pereiopods are uniramous, but the pleopods are biramous.

A number of isopod groups have evolved a parasitic lifestyle. The suborder Epicaridea is exclusively parasitic, while the polyphyletic suborder Flabellifera is partly parasitic. Cymothoa exigua, for example, is a parasite of the spotted rose snapper fish Lutjanus guttatus in the Gulf of California; it eats the tongue of the fish, and takes its place, in the only known instance of a parasite functionally replacing a host structure.

Cymothoa exigua or the Tongue eating louse is a parasitic crustacean of the family Cymothoidae. It tends to be 3 to 4 cm long. This parasite attaches itself at the base of the spotted rose snapper's (Lutjanus guttatus) tongue, entering the fish's mouth through its gills. It then proceeds to extract blood through the claws on its front three pairs of legs.

As the parasite grows, less and less blood reaches the tongue, and eventually the organ atrophies from lack of blood. The parasite then replaces the fish's tongue by attaching its own body to the muscles of the tongue stub.

The fish is able to use the parasite just like a normal tongue. It appears that the parasite does not cause any other damage to the host fish. Once C. exigua replaces the tongue, some feed on the host's blood and many others feed on fish mucus. They do not eat scraps of the fish's food. This is the only known case of a parasite functionally replacing a host organ.

There are many species of Cymothoa, but only C. exigua is known to consume and replace its host's tongue.

In 2005, a fish parasitised by what could be Cymothoa exigua was discovered in the United Kingdom. As the parasite is normally found off the coast of California, this led to speculation that the parasite's range may be expanding. However, it is also possible that the isopod traveled from the Gulf of California in the snapper's mouth, and its appearance in the UK is an isolated incident. The animal in question will be put on display in the Horniman Museum.

In 2009 another "tongue-eating" isopod was found by fishermen inside a weaver fish off the Jersey coast.

British scientists are on track to develop a new robot which they claim will be controlled by a blob of human brain cells.

According to the New Scientist, a team at Reading University, which has already used rat brain cells to steer a simple-wheeled robot, is now trying the same thing with human brain cells.

In fact, for the robot with rat brain cells, 300,000 rodent neurons grown in a nutrient broth and producing spikes of electrical activity were connected to output of the robot's distance sensors. The neurons proved capable of steering the robot around a small enclosure.

According to the scientists, observing how the neuron culture responds to stimulation can improve the understanding of neurological conditions such as epilepsy.

To make the system a better model of human disease, a culture of human neurons will be connected to the robot once the current work with rat cells is completed. This will be the first instance of human cells being used to control a robot.

One aim is to investigate any differences in the behaviour of robots controlled by rat and human neurons. "We'll be trying to find out if the learning aspects and memory appear to be similar," said team leader Kevin Warwick.

The scientists can proceed as soon as they are ready, as they won't need specific ethical approval to use a human neuron cell line. That's because the cultures are available to buy and "the ethical side of sourcing is done by the company from whom they are purchased", team member Ben Whalley said.
