Australian Aboriginal
Progenitor?
We were taught that anthropologists knew it all, and everything they held about human evolution was correct. Human lineage could be placed on a timeline This is now proved to be incorrect: Papuans came out of Africa much earlier than the 50,000 to 80,000 years assumption. These people left the continent of Eden at least 100,000 yrs ago. The Original African theory supposed an Eve living as far back as 200,000. | ▶ not. |◀ |

African man
Adam?
Professor Alan Wilson has put forward the hypothesis that Australasia could be the fountain place of Man. Aboriginals have the highest rate of genetic mutation of any "race". Mitochondrial evidence along the female line proves this. A colleague of Alan Wilson, Rebecca Cann, suggests the combining of two human lineages in Aborigines pushing modern Man back 400,000 yrs. | ▶ | stories not | ▶ |    

There is another big mystery: humans have always lived alongside dogs. The presumption is that Africans travelled all the way to the Indonesian Archipelago with canines, but did not take them to Australia - very odd indeed. The British brought dogs in the eighteenth century. Dingoes escaped from fishermen journeying from Southeast Asia only a few centuries before. The Asian dog is a dingo. | ▶ | not. | ▶ |   | ▶ | not dogs | ◀ |

Myopia is Genetic - Health

Myopic vision is genetic as well as Environmental - Health.
Myopia is a very odd condition. Shortsighted people can only focus at a close distance because their eyeballs have grown too large. It is not so much an illness as a consequence of growing.
It is a genetic problem. About 90 per cent of East Asians suffer from myopia. This compares to 25 per cent of Australians. Too much reading indoors is a causative factor. The more years one partakes in education the higher the probability that shortsightedness will occur. Spending time outdoors where it is necessary to focus on things at a distance seems to be preempt the ailment.

Getting glasses does treat the condition. However, it can lead to problems in the future. There is a higher possibility of going blind. Detached retinas and glaucoma lead up to this.

The age of technology has not been a factor in myopia. Yes, there is a lot of reading on tablets which is detrimental. Whether reading a book or looking at a screen, there is no difference.

Cause of Sudden Death in Young People is Genetic

Sudden death in young people has a genetic cause - Long QT syndrome.
There is a predilection for some young adults to suddenly die. In a way it is similar to cot death: until now the cause was unknown. The "disease" has been identified and is called Long QT syndrome. A third of sudden "unexplained" deaths in people up to their mid thirties die of heart rhythm complications due to the inherited illness. The heart problem is not always evident in autopsies.
Long QT syndrome
Parents can also die of the condition in later life. The faulty gene runs in families and is generally passed on to some offspring. A gene testing study of children having symptoms of heart disease is showing that many carry the gene. 

Ongoing monitoring of youngsters is saving lives.  However, there is no official program that tests all children.  Some, of course are not diagnosed early and it is these who are at risk of sudden death.  It is heart breaking for a family to lose a child in this way,Ea

Insurance Companies to Force Genetic Testing

Life insurance is a con. We all know that. They take your money. Then when you make a claim they force you into court to make you back down or run you up a huge legal bill. I cashed my life insurance in when they stopped paying the share investment bonus that doubled what you paid in. Now if you close the policy you get back "less" than you paid in premiums.
Insurance companies want compulsory genetic testing
No one is perfect out there, so when they say they will make people have genetic tests before they can take out a policy you should be afraid. The big three insurers say they have not had one complaint from consumers so far. Unfortunately, the ones who had genetic tests have not made any claims yet. There will thousands of complaints when the insurance companies fail to pay out.

Thankfully, you cannot be forced to have a genetic test currently. However, you must hand one over if you have already had one - by law. Just why the government made giving up private information compulsory under force of law is a mystery.

Of those who have had a test or have had one when instructed by insurers (400), a very high 20 percent were refused cover. This is much higher than the half a million who gained cover without a test.

Women and Men Were Not Equal in Hunter Gatherer Societies

Men and women in hunter gatherer societies had very defined roles. Men hunted for protein, namely meat. Women sought tubers and berries for long term family sustenance. Some scientists are saying that male and females were more equal in prehistory. This not really the case.
Male hunter gatherer man
Women, for example, could not go on the hunt with men. Males would not remain home with the women unless sickness prevented the hardships of seeking wild game. A women who did not find a mate had to remain home, unwanted, with her birth family. Indeed close breeding was frowned upon. Mates were invariably found in an unrelated group.

Scientists have mistakenly confused female independence in decision making, which supposedly pushes them to choose an outside mate, with women knowing that it is the wise thing to do, while males are dumb and stupid about this. The attraction between cousins is well known - thus the term "kissing cousins". Why would women have superior ideals than men. They wouldn't. No, it is something genetically inherent in Man that drives individuals to find unrelated mates, loose liaisons with cousins not withstanding.

If males saw nothing wrong with interbreeding they would clearly have forced their will on females. Since the beginning, males have always dominated in mammals. Women could not have forced their will on men, apart from persistent verbal onslaught. It is known that females do dominate the verbal sphere.

The scientists have it wrong. Women are persuasive over males in one-to-one negotiations, but in groups matters men would govern and set the rules. Men clearly felt that pairing with outside parties was a "natural" thing to do.

New Catfish Species in Australia

Carfish are fairly mundane creatures. If you are fishing and you hook one thinking it is a big pike you are annoyed when you drag it in, and "drag" it the defining word. They are usually a dead weight on the line.

On the other hand if you are a biologist all animals are of interest. A combined US, Australia team has discovered a new catfish species in North Queensland. It has a tail like an eel, not the usual fish-like tail. Apparently, people knew of its existence for many years and just assumed it was like any other catfish.

Tandanus tropicanus is cylindrical in body shape. It has a large head and tiny eyes. DNA tests showed that the fish is a distinct species. Overall, its body configuration is different from other catfish.

Unlike many catfish it is good to eat. Fishermen have been catching it for many years for food not knowing how unique it was. Despite the accumulation of human knowledge about the world there is a lot we still do not know about nature.

Black Tulips and Blue Roses - All Is Possible

Black Tulips and Blue Roses - All Is Possible

The black tulip will soon be a reality. Development of a blue rose has nearly be achieved. A new rose that is "nearly" blue is soon to be released onto the Japanese market. The asking price - a quite low $30 each.

There is no blue pigment in a rose, so it is impossible for a natural rose to display this color. The tone has to be put into the plant. It has been done by genetically splicing color into the rose from Petunias. This flower has a blue pigment called Delphinidin. The combined project by both Japanese and Australians has taken twenty years to create the "blue" rose.

American nurseryman Samuel Parsons said as long ago as the 19th century that one day scientific advances would lead to the cultivation of a blue rose. Attempts have been made in the 20th century. A blue-grey rose was bred, but it flowered only once.

For many years roses dyed blue have sold well in England. Unfortunately, horticultural advisor to the Royal Horticultural society, Helen Bostock, believes a blue rose will not be accepted. She is probably wrong about this. People are fascinated by anything new. It is probably "sour grapes" that the blue rose was not created in England. Another English rose grower Bernard Mehring is a bit miffed as well. He says he wouldn't grow it in his garden. He wants British controls to keep the plant out of the country. This is a sad situation that wreaks of elitism. China, however, will want the new rose because there a blue flower signifies hope toward reaching an unattainable love.

Cleanliness Causes Type 1 Diabetes

First we have a clean childhood leading to Crohn's disease. Now we have cleanliness causing type 1 diabetes. Both, apparently, are caused by the same thing - the lack of "bugs" in the stomach.

In the case of Crohn's disease it is the absence of worms. With diabetes it is too few bacteria. Tests on mice showed that a completely germ free environment when young increased the frequency of mice developing type 1 diabetes. Much fewer mice got diabetes when exposed to bacteria.

Future treatment could involve people taking medication containing bacteria. Potential sufferers of diabetes can already be identified by testing their genetic make-up.

Culling Could Destroy the Tasmanian Devil

Tasmanian devils are still under threat despite culling programs. Far too many devils must be killed to eradicate the Tasmanian Devil Facial Tumour Disease (DFTD), so many in fact that it could decimate the Animal itself. During the incubation period of the disease, devils have no facial deformity and these animals slip through the cull net.

Current estimates give the Tasmanian devil only 25 years for survival in the wild. Work is in progress to find a vaccine. An "insurance population" is being established on the Australian mainland. And devils in north-western Tasmania have a natural genetic resistance; the spread there is slowing.

Just why the disease developed is unknown. It began in 1996. Because devils bite each other during normal interaction, DFTD spreads rapidly. The devil population has fallen by 60 per cent due to the dangerous facial tumour disease.

High Blood Pressure Caused by Many Genetic Variants

It is now common knowledge that the propensity to get high blood pressure is genetic. A billion people in the world suffer from it. Persistent high blood pressure ultimately leads to heart disease and stroke.

The genetic work is complicated. Sixteen new genetic variations have been identified. These genetic factors can be counted: the greater the number people have the more likely they are to suffer from high blood pressure.

There are three kinds of genetic variants predisposing hypertension. One regulates blood pressure. Another affects pulse. The third type controls arterial pressure.

It appears that the modern diet has happened too fast for humans to stop the selection of these gene variants. Children are now suffering from this complaint. The variants will only be "selected-out" if these children do not reach child bearing age. This is a hard fact to accept, but this is the way natural selection works.
