Dingo is a Mystery to Science

Science: Dingo dog came to Australia via Southeast Asian seafarers.
Archaeological evidence shows that dingoes arrived in Australia 4,000 years ago.  There is no mystery as to who brought them.  Southeast Asian seafarers did land in Australia to get fresh water and herbs to treat constipation.

The dingo is common across the world today, all the way from India to the Pacific islands.  In news videos you see dogs roaming about the street in the background that are absolutely identical to the dingo, same upright tail, same color coat.

People chosen as the distributor of the dingo are the Lapita who moved eastward out into the pacific.  This choice is just for convenience.  It is definitely wrong.  The dog is common everywhere.  Let's face it, Timor is so close to Australia that sailors obviously landed here, often.

Genetic evidence places the origin of dingoes in China.  This is only where the breed began.  It rapidly spread to every country in Asia and Southeast Asia.  The dog is definitely a meat eater though.  It does not have the capacity to digest starch, so it is said that they did not live with agricultural people.  But weren't the Chinese mainly farmers 4,000 years ago?  They still are!  Dingoes are ancestors of modern dogs, not the other way around.

Sociolology: Women on ebay Sell at a Lower Price

Sociology: women make more profit on eBay by selling at lower prices.
Men and women are the same - well not really. There may be a drive to make the workplace equal for both sexes. However, there are clear biological differences and thought processes are not the same. Certain parts of the brain are preferred by either sex.  What is involved in selling? Description and layout are paramount. Relevant and stimulating pictures are required. The correct price to sell an adequate volume of a product and make a profit are also essential.
Men and women see these factors differently. An examination of eBay shows that women sell the same products at lower prices than men. Considering people can easily find the cheapest product in a category because of the way eBay is designed, women managers will make more sells.

Researchers said that buyers have lower expectations of women sellers. This is a red herring: buyers do not normally look to see whether a seller is a man or woman. I for one, search for the best value at the lowest price. Sociologists are prone to make errors in the desire to find relationships.

Yet some women do seek out women sellers. Men couldn't care less. Whether women buyers do this for a lower price is debatable. Perhaps women are better than men at business generally. Many men do believe that the world owes them a living.  This is seen in supermarkets when a new young male manager stops marking down specials. Goods do not sell and are ultimately thrown away.

I would say sociologists clearly made wrong assumptions about this study. They did not look are overall profit. Perhaps women sold more goods and made more money. Omission of theis vital information could be seen as manipulation of data. ◆

Biology: Atlantic Molly fish of Mexico survive high hydrogen sulfide acid.
There is hope for the future of fish as the world is polluted more every day. Some fish can live in extreme toxic, acidic environments. For example, the Atlantic Molly fish of Mexico can survive high levels of hydrogen sulfide acid. They are the only fish in volcanic freshwater springs.
Atlantic molly fish

Mollies do not filter out the toxin. They turn on certain genes that do the filtering job for them. Of the fish's 35,000 genes 170 are enhanced in the process: these linked genes are all involved in removing hydrogen sulfide.

If things get serious and species of fish begin to die out, this group of genes could be "spliced" into the gene structure of endangered fish. They would not be the same fish, but at least some vestige of the evolutionary sequence of dying fish would live on.

Is Australia More Equal Than Other Countries

SOCIOLOGY
Class in sociology is based in income - low, middle and high income earners, plus wealth. This is in conflict with assumed class by the ordinary person who believes that class is based on status. In England, for example, one's position in society can be inherited. An English earl will remain high class even though he has little income and lets the paying public into his home to pay for its upkeep. Anyway, let's get back to the issue, "at large", which is how income and wealth inequality has changed in Australia.
Income and wealth equality in Australia
Egalitarianism is an Aussie "thing". There is a strong belief that all Australians are equal, in daily interactions at least. An Australian can have a drink with the CEO of the business where he works. In England this is unthinkable. It simply will not happen because the boss will not allow the lowly employee into his/her circle.

In the 1950s income in Australia was relatively level. It was far more equal than in other Western countries. It even got more equal until the late 1970s. There has been a widening gap in income since then.  The Gini coefficient which measures income differential rose from 0.27 per cent in the early 1980s to 0.34 in 2011 (when one household has all the income the coefficient is 1.0).

Wealth inequality has, unfortunately, not been tracked over time. This is an unfathomable situation. After all, this should be a thing of great interest for sociologists. We do know the present state though. The wealthiest 20 per cent have A$2.2 million dollars in assets. The poorest 20 per cent have an average of $31,000. Of course, some people do not have any real assets at all.

How does Australian stand in regard to other nations? Of the 34 OECD countries, Australia is number 23 on the measure of income equality. On wealth Australia does much better. The Credit Suisse Global Wealth Report puts Australia as the second most equal country of 34 "advanced" nations, after Japan.

Australia - Interesting Things

science
Interesting things abound about Australia. It is a unique continent being isolated from the other land masses for millions of years. Animals have evolved with unusual behaviors. The cute, tiny Antichenus gets so high on testosterone that the little fellow doesn't eat or drink. He mates until he dies.
antichenus
The ugliest fish live in the deep sea off Australia's coast. They have large eyes, a necessity where light is almost total nonexistent.  Land creatures have evolved where some beauty is required to facilitate mating.  living in the darkest depths means seeing your mate is not so important, but large eyes, huge jaws and venomous spines are.
Australia's ugliest sea monsters
Tourists and locals know about the deadly creatures living here. Oddly, Funnelweb spiders are not dangerous to dogs, cats, mice, lizards or snakes. An unlucky human can die if bitten by this spider.  Muscles in our bodies fibrillate.  Unsynchronized contraction of heart muscles can kill us.
Bundaberg is the home of the world's oldest tagged turtle. X23103 is a flatback turtle. The tag was put on in 1976 and she has been tracked ever since. The old lady continues on her way at the age of 60 years.

Europe is well known for its stinging nettles. Children try all ways to stop the painful sting. Australia has the little known Gympie-Gympie stinging nettle. If its large leaves are just touched by human skin a part of the leaf breaks off and embeds itself so that it cannot be removed. It is a painful reminder to steer clear of it.

Forget Brazil and the rest of South America, Australia has the last remaining regions of wilderness. Cape york on Queensland is virtually untouched native vegetation. It has mangrove swamps, wetlands, tropical raingforests and eucalyptus wooded savannahs, home to ancient wildlife.

The longest "range" of volcanoes stretches down the eastern seaboard from Queensland's Pinnacle Rock all the way down to Melbourne. It is three times longer than the Yellowstone National Park volcanic track in the U.S.

Australia Invents the Utility Car - the Ute

Motor cars rapidly became popular in the bush when Henry Ford introduced mass production lines that reduced their cost to within everyone’s reach. Farmers used their car to carry all sorts of ‘junk’ - from pigs to ploughs making a mess of the inside, so they resorted to cutting the back end off and fitting a tray behind the front seat. This worked, but was not very safe for the goods on the tray and dangerous when carrying livestock.
Worlds first Ford utility invented by an Australian
In 1932 an enterprising farmer wrote to the Australian branch of the Ford Company telling them that like most farmers he was unable to afford both a car and a lorry. He was fed up with cutting his hands and his farming goods on the rough edges of the tray fitted to his makeshift car/truck. And his wife continually complained about riding to church in her Sunday best in a smelly vehicle.

He asked Ford to design a purpose-built vehicle, one that he could use to take his pigs to market, pick up stock feed during the week and drive to church in comfort on Sundays. Lewis Brandt, a 22-year-old Australian engineer working at Ford set to work and designed the Australian Utility that came off the production line as:

"The Ford Coupe Utility - This utility model has a smart Coupe body similar to a passenger car type with fine interior fittings. Rear compartment has ample loading space."

 This was one of the first advertisements to appear for the new vehicle, the world’s first successfully mass produced one-piece coupe utility body that went on to sell in its millions throughout the world.

Little Penguin of Australia and New Zealand are Different species

Animals may look alike and are asumed for decades as being one and the same, but scientists are often wrong. Australian and New Zealand little penguins (Eudyptula minor) look identical, However, new reseach shows that they are different species.  The cute little penguin is the smallest of all penguins. It is only 30cm tall. It lives along the southern coast of Australia and coastal New Zealand.
Little penguin of Australian and New Zealand
Many scientists find it surprising that two different species inhabit the same region and look very much alike. The answer lies in the nature of the niche. Animals evolve to take advantage of a particular niche, so to a large degree the niche shapes the animal.

There is strong opinion that the Australian little penguin should be given a name. A name has been put forward: Eudyptula novaehollandiae. There is a problem as the Australia species is also found in Otago on the southernmost tip of New Zealand: how they got there is a mystery.

Drones Used to Control Sharks in Australia

Australians tend to be early adopters of new technology because they have inquisitive minds. Our old enemy, the shark, will always be around, so it is not surprising that drone technology is being used to solve this problem.
Shark caught by baited hook attached to a drum
It is not the buzzing sound that will scare sharks off. Drones are being used to gather visual information about where sharks are and the number swimming around, the theory being that if we know this we can be more careful.

At the moment hooks are baited on lines attached to floating drums. This method is a simple way to catch sharks, but other creatures are also caught such as dolphins. Unfortunately, sharks not tempted by the bait remain in the area. Baited hooks have warning devices in them that notify watchers on a boat when sharks take them.

This is a clumsy way to keep sharks at bay. Targeting sharks observed by drones is a better solution. Drones are far cheaper than helicopters and do a better job, going right down to sea level to collect data.
