Though jellyfish have no brain, intelligence is built into their bodies. They appear to act on instinct to changes in the environment. Whether they have consciousness is not known. They swim better than any other creature. Swimming against the tide is their forte. Detecting the direction of currents was thought to be impossible without sight, yet jellyfish do it. Rhythmically moving their heads and forcing water out from their bodies, they are a jet-propelled swimming machine. Most believe that jellyfish just drift. This is not the case, They head straight for their destination, for example, usually in groups. Somehow they know that there are others of their kind with them, though they do not have eyes. Perhaps the animal uses the Earth's magnetic field as well as ocean currents to know where they are. Some scientists have suggested they use infrasound. ✴ Science by Ty Buchanan ✴ http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blog

You may stop fearing an asteroid colliding with the Earth. Man himself could be the cause of the next mass extinction. People who harp on about climate change being a religion and an article of faith are like those who ignored Noah. Remember that humans got down a few hundred individuals in the past. We are very lucky to be here today. Of course the world would have gone on without us: it would be a very different world. There would be no pollution anywhere. Ebola is out of control. Antibiotics are failing. A world-wide plague could be on the cards. Danger to Man is not the only issue. Twenty five per cent of mammals could soon disappear. Forty per cent of amphibians are at risk. Because species are already dying off, a mass extinction could have already begun. The hottest decade on record shows that life is declining. When animals die off the food supply for other creatures also goes. So the path of extinction of predator species becomes real as well. Carbon is the maj

Australopithecus africanus were much like humans. They had evolved to use their hands to do intricate thing. It would have been possible for them to turn a key or hold a hammer. Coming down from the trees "caused" manipulatory advancement. The most useful attributes spread to more of their number due to longer survival and breeding capability. While anthropologists are not sure that they used the advanced abilities, it is highly probable that they did otherwise the traits would not have become dominant. This pushes tool use way, way back to 3 million years ago. How do scientists know that Australopithecus had complex skills? Trabeculae which is inside bones in the hands shows how hands were used. Humans, for example use the fingers and thumb region more than chimpanzees. Our friendly relations mainly use their fingers. The supposition that tool use began millions of years ago was only theory: now it is proven.  Culture must have been passed on to offspring as well.
