Fossil of Earliest Flesh-Slicing Fish from the Jurassic

The fossil of a fish much like a piranha appears to be the earliest flesh-eating fish. It was found in Germany. Having teeth similar to a piranha it lived 150 million years ago. Remains of its victims were found nearby. It mainly ate the fins of fish. Evolving to consume only fins was a survival mechanism. Fish that were attacked did not die immediately. They survived to provide a meal another day. The hunter's teeth were triangular. With serrated edges, they were ideal for cutting flesh. Initially, bony fish could only bite chunks of flesh out of prey or swallow them whole. Slicing of flesh appeared much later. The hunting method of the fossilized fish was identical to modern-day piranhas. Injuries to the attacked were the same. The ancient specimen was a sea dweller. Piranhas live only in fresh water. Oddly, some piranhas are vegetarians mainly eating seeds. They are a normal food for South American people who say they taste like any other fish. It is not understood why they

Jellyfish Numbers are Increasing Because of Humans

Jellyfish are spineless little devils. I do mean that in a good way. They are the most efficient swimmers on Earth, pulling their way forward rather than pushing. The "immortal jellyfish" rises phoenix-like from the dead. When it dies the decomposing body puts out stolon stalks which become babies. They are rapidly increasing in the world's oceans due mainly to Man. Most variations breed under man-made marine structures such as piers. The killing off of predatory fish for human food allows the transparent creatures to vastly increase in number. Cyaneidae have caused many problems over the years. Those going for a swim regularly get stung. In 2006 the seemingly invulnerable USS Ronald Reagan was put out of action by masses of jellyfish clogging the cooling system. Power plants and desalination facilities have also been stalled. Two million workers became unemployed when the comb jelly native to North America invaded the Black Sea in 1980 and destroyed anchovy

Giant Chickens Roamed Australia

Xmas dinner would be a real pig-out if the giant chooks were still around. ◘1 Giant for Chickens or Roamed it xxxxxxxx giant ◘1 Large flightless birds in the northern and southern hemispheres evolved independently. This proves that animals evolve to fill environmental niches. Chicken-like birds as large as a horses lived in Australia 50,000 years ago.         ◙2 yyyyyyyyyy giant roamed chickens giant ◙2 If they were around today, they could provide an evening meal for a whole street. Imagine the size of eggs in the supermarket. Of course there would be a lot of humongous animals running around trying to eat us.   ⦿3 zzzzzzzzzzz in roamed on chickens in giant large birds ⦿3 Dromornithidae  were not exactly like chickens. They had bulbous beaks and weighed in at 650  kilograms . Not related to emus, they roamed right across the continent.  Mihirungs  fossils dating back 50 million years have been found.       ⧗ sex ⧗      ⧗ or animals ⧗ It is presumed that the common ances

Single Sex Schools Have Poor Outcomes - Society

Single sex schools are bad for society. Despite excited parents claiming that putting children in single sex classes improves life outcomes, in reality this is far from the truth. Single sex schools, for example, foster gender stereotyping for girls as well as boys. An extremely large study on students in 21 countries found those in mixed sex schools fared better than those in single sex schools. The cultural outlook nurtured by SS schools damaged students for life. It is about time this silliness is stopped, and the fad is put to rest. The world is not made up of one sex. Indeed, there are multiple sexual categories today. Everyone has to fit into this world. Molding people to strongly identify with one category puts them at a disadvantage.  It is not the curriculum that does the damage: it is the socialization process. Narrowly adhering to things about one's own sex does not make for efficient interaction with both males and females in the workplace. Principal

Supernovae and Black Holes Increase Radiation Changing Evolution

Evolution speeds up with cosmic activity. Most people assume that we are isolated here on this tiny planet called Earth. However, throughout the ages life has been impacted by what goes on out there in the cosmos. Humans would not be dominant in the world today - considering we got down to less than a hundred souls when the climate suddenly took a new direction. An arrow piercing a supernova? When astrophysical phenomena such as black holes send out x-ray flares it affects earthly evolution. It has estimated by computer modelling that two supernovas occurring close together increased radiation on marine life by a factor of three. This is a major change that nascent intelligent life had to adapt to. Radiation sends out muon particles which hit the ground. More of them alters the environment. DNA mutation will speed up, so evolution becomes more rapid. This would account for the sudden disappearance of established species and takeover by new ones. The dark clouded

Life on Saturn's Moon Titan - Chemistry

Science sees life on Saturn's moon Titan. Looking for alien life on planets like our own is tunnel vision. Believing that life can only exist on planets in the "sweet" belt is silly. The universe is a place of commonalities, yes. However, it has many types of environments from the very cold to the extremely hot. Saturn's moon, Titan, could have microbial life even though it is indeed frigid. The body has all the chemical requirements for life creation to occur. Titan is a carbon copy of Earth, except the lakes and rivers are methane not water. Much of new science is bringing down temperatures so that chemical reaction can be controlled, so it is nonsense to premise that there is not sufficient energy for molecular interaction to happen at -179C on Titan. The key chemical hydrogen cyanide (HCN) is present on Saturn's satellite. Martin Rahm of Cornell university holds that the clouds of Titan could absorb energy from the distant Sun. The energy w

Genes Cause You to be Happy or Depressed

Your general outlook of is genetically linked, Whether you suffer from depression or are happy. Depression can be an inherited trait. Research has shown this to be the case, so could a happy personality also be genetic? Of course, it will have not effect on creativity. Many high achievers through history has suffered from dark periods in their lives. It could be said that perpetually happy people have nothing to strive for and are less likely to leave their mark, unless they have careers as comedians. Happy people do seem to have certain genes, however. Three gene variants are linked to a happy outlook, while two are causative factors for depression. A whopping 11 variants are responsible for neuroticism. If you are a pain in the .... to everyone else it could be those dozen or so genes - there is bound to be another gene in there somewhere. The above findings were identified in a major study involving 3,000 participants. It was concluded that genetic causation was weak.

Unhappiness Does Not Shorten Life

Being happy helps you to live longer right? Wrong! The grumpy old man is real. He just makes life miserable for everybody else. People have to earn a living. Many jobs, particularly the monotonous production line ones, are boring, tedious and soul destroying. Unhappiness is the consequence. Poor health can also contribute to discontent. Unfortunately, only a group of women in their sixties were surveyed. This is neither young or old. I wonder why they didn't examine elderly people? Ah well, scientists work in mysterious ways. If you are chronically ill, you could behave in a way that does shorten your life, like giving up exercise and adopting a poor diet. Some even harm themselves which does damage the body, but does not really shorten life. It seems 83 per cent of women in their sixties are "generally" happy. This is very high. It needs to be qualified, however, as 44 per cent said they were "usually" happy. There was another choice: "happy

Life Began on Earth 4.1 Billion Years Ago

Life began on Earth earlier than thought.  There is evidence of life 3.8 billion years ago.  This is only 0.7 billion short of the total life of the planet. A new study has pushed the origins of life back another 300 million years. It seems life began as soon the chaotic period of Earth's formation had settled down. Flecks of graphite were trapped in the crystal zircon.  This microscopic carbon mineral is among the zirconium, oxygen and silicon which is the main structure of the crystal. While trapped graphite is not full evidence of life, carbon is classed as biogenetic - life needs it to begin.  It is believed that the graphite was originally organic before being absorbed by zirconium.  Apparently, Earth calmed down very quickly after formation. Estimates now puts the origin of life on Earth at 4.1 billion years. ◆ Biology Ty Buchanan   ◆ Adventure Australia Funny Animal Photos Funny Weird Things Articles News Reviews ● Vista Computer Solutions Blog
