Birds Sang in Australia First

The first singing birds originated in Australia - science.
Singing birds originated in Australia. This is true. Just when they moved to other parts of the world is not yet clearly known. Evidence from DNA sequencing and fossils point to this happening approximately 23 million years ago.

They first "hopped" from island to island until they reached Indonesia. From there it was easy for them to spread to Asia. The progression to populate the world occurred rapidly, like when humans moved out of Africa.  It took only a few thousand years for the initial "breakout".

Birds of song could not leave Australia before 23 million years ago as Indonesia before that time was a small island and there was a huge distance of ocean for the birds to cross to reach other land masses.

Half of all bird species are song birds. The only continent where they did not go is Antarctica. This is a mystery because penguins are birds, so the cold barrier is not significant for birds.  Many native song birds died out in Australia due to the climate making the continent arid.

New Clam in Australia

There are many kinds of clams, some of them very large. The bigger ones are classified as "giant" clams. All were thought to be known. However, a new species has been identified. Examples were found at Ningaloo in Western Australia and near the Solomon Islands.

The reason it has been overlooked for so long is because it is very similar to Tridacna maxima, which is quite common. There are a plethora of colors including yellow, green, brown and blues. They are in many different shades of these main colors.

Clams produce large amounts of edible meat for human consumption. Their shells are also valuable for displays. Many species are under threat. They cannot run away and hide from divers and snorkelers. Two similar species in the same region means numbers for each are lower than first thought.

Land of Mu in Indian Ocean?

Those who study ancient records have presumed that the claimed submerged continent of Mu was in the middle of the Pacific. They may be looking in the wrong place. An undersea continent has been identified beneath the Indian Ocean.

It was not sin or playing with dangerous science that caused the destructive disaster. Tectonic plates moving apart split the continent into many islands. Beneath the waves lava flows have covered the ancient land near the Seychelles which was part of the Indian subcontinent.

The region which includes the Seychelles, Mauritius, Maldives and Madagascar has an anomaly. It has a stronger gravitational field than other place around the world. This is because the crust is 25 kilometers thick, compared to as little as 5 kilometers elsewhere.

Islander Blondes Are Natural

All black people have black hair - right? This is an incorrect assumption. When Europeans first arrived in Australia they found some blonde Aboriginals. They thought that White sailors must have been shipwrecked off the coast and took Aboriginal wives.

In the Solomon Island near northern Australia 10 per cent of black people have blonde hair. The sun has not bleached the hair white. European sailors are not responsible either. It is a random gene that causes it. This is proven as the tone of blonde is different from Europeans.

A group of Islanders were tested for gene structure: forty two with dark hair and 43 'blondes'. The pigmentation gene was either coded with a "c" which produced blond haired people or 'T' giving dark hair. It is a recessive gene which means both parents must have the blond gene to have a blond child.
