Shark Ancestor had Bone

It was though that the evolution of sharks was known. However, a 380 million year old fossil found in the Kimberley region of Western Australia indicates the presence of bone as well as cartilage. In other words a virtual missing link has been found.

It means that an ancestor was a bony fish. Obviously, they lost the bone, lightening the body, to enable them to swim faster. The theory of a lineage containing only cartilaged ancestors has now been dropped. This is an indication of accepted beliefs about life in general being without foundation.

Animals with only cartilage were thought to be more primitive than boned ones. Accepted for centuries, this concept was incorrect all along. Be careful what you believe. This could be extended to the religious sphere. You could be following a false faith.

Man Still Has a Hunter Gatherer Body

The big debate - has Man evolved to eat anything? Of course, eating everything is a huge claim. Human beings have only lived in large groups for 10,000 years. Is this time enough to evolve to eat processed foods? Personally, I would say no. Even scientists who claim this are misguided. They are believing their own propaganda.

Paleo diet of primitive man hunter gatherers

Evolutionary biologist Marlene Zuk says evolution over the last few thousand years has allowed us to digest milk. Don't be fooled by the expertise claimed by this scientist. It should be remembered that many people especially Asians still cannot consume milk without becoming sick. This evolutionary "benefit" is not yet complete. She also says that the hunter-gatherer diet is not known. This is wrong. A great deal is known about the diet of primitive Man. Study of isolated African tribes shows that women collected tubers and berries while men brought home meat every few days. This did not change for hundreds of thousands of years.

Until the last century most humans lived in sparsely populated regions. Was evolutionary "progress" sufficient to change the dietary capability of people in such a short time? Certainly not! Ms Zuk's claims are rubbish. It has been proved that autism is dietary in nature. Changing a diet improves the well being of a sufferer. Scientists still ignore this proven truth.

Processed food may keep you alive but it makes you suffer as well. High intake of sugar for the general population began in the United States in the early 20th century. The Americans were fatter than the British, for example, at that time due to the sugar. Only the wealthy could afford sugar in 19th century Victorian England. Unfortunately, the Western diet has spread throughout the whole world. The problem with processed food is that vitamins, minerals, protein and particularly carbohydrates can be concentrated into a product, but toxic elements are concentrated as well. However, we do not know which elements are making us ill. Carbohydrate gives potent amounts of energy, but it also makes us fat if we don't use it.

New Peacock Spider Species in Australia

The discovery of new species in Australia is no longer a surprise. However, it is extremely interesting. Jumping (peacock) spiders, Salticidae, are the largest family of the Araneae. Peacock spiders are so called because of their bright colors.

Skeleton spider Skeletorus, Maratus sceletus

Two new species have been identified. They are named Skeletorus, Maratus sceletus, and Sparklemuffin, Maratus jactatus. The former is black with white stripes and some blue in the background. It does look like a skeleton. Sparklemuffin is blue with a unique red pattern.

Peacock spiders jump and dance around showing off their colorful abdomens. Due to prevalent predators males need to be seen by females to successfully breed and continue their existence. They have adapted well and have diversified into many types.

Pheidole Ants Rule the World

Man is not the only animal to dominate the Earth. Pheidole ants have spread over all the livable continents. They are so common that a walk in a tropical forest means some are killed by just stepping forward.

There are 1,200 species of the genus Pheidole. Each has developed to exist in a particular niche of the ecosystem. In a study of 300 species it has been found that certain species evolved similar characteristics independently.

Species proliferated dramatically - from one to 600 species in the Americas. The evolutionary goal was to dominate all niches, first in the New World then in the Old. Expansion across one was independent of the other. Evolution took its own course.

Ants are essential for healthy ecosystems. They aerate the soil, disperse seeds and help move nutrients. In biomass they equate with all vertebrates. Their study is indeed important

The Environment Affects Us and Our Health

The type of environment affects the mood of people. This is not surprising when one considers that Man a creature of his habitat. What the senses perceive shapes the human animal. As humans responds to what is "Out there", so evolution ensues.

A "noisy" environment, bright colors and loud sounds, stimulates us. Furthermore, it puts us on edge. The body is prepared to take action of some kind. Communication of three bodily systems (nervous, immune and endocrine) work against our wishes to bring this about.

If we want to get away from high stimulation we need to move ourselves to a soothing environment. People know this full well. A quiet snooze in front of the TV after dinner at home is always relaxing. Adrenaline, noradrenaline and cortisol levels drop.

In an emergency stress gives us two option: flight or fight. If we cannot move away from hostile surroundings, we must put on a brave face and tough it out. Bluff is also part of flight. However, remaining in an uncomfortable situation for long periods has its costs.

Today employment is structured and we cannot leave to silence out bodies. Stressful chemicals continue to pump through us causing long term damage. This is due to normal repair functions of the body being turned off. Inflammatory immune response is raised which is good only for the short time. It must be noted that 90 per cent of all human disease is related to stress.

New Mushroom-Like Organisms found off Australian Coast

There may be alien creature "out there" - Well many believe that there is - but some weird things live on this planet. In the ocean depths of Australia odd living organisms have recently been discovered.

At first glance they look like floating mushrooms. They are not related to fungi though. The creatures are actually flowering plants and vertebrates. Dendrogramma mostly consist of a stomach surrounded by jelly-like skin.

Scientists believe they are the remnants of early life forms which appeared before the life that went on to dominate the Earth. In other words they were a dead end. They are unique, not related in any way to life that eventually became successful across the globe.

There are a lot of new things still continuing their existence at the bottom of the oceans. Many are very specialized living off toxic substances that would kill other organisms. Don't bother to look for life in the stars. Much still awaits discovery beneath our feet.

Dingo is Just an Asian Dog

New research tells us that the dingo is a uniquely Australian dog. This is despite the strong evidence of Asian dogs looking exactly the same and in Asia they are domesticated. This silly "mythification" of animals in Australia says something about Australians generally. Are they seeking something to make themselves unique?

Australian academics have revived the name Canis dingo a term coined in 1793 by German naturalist Friedrich Meyer. Skulls examined by researchers showed the dingo had a long snout and a broad head. A look at a modern dingo in the bush shows it to be exactly the same as Asian specimens living today. There is nothing special about them. Because they are inter fertile with ordinary dogs shows that they cannot possibly be a different species. Their offspring in this case are also fertile. Unlike the donkey which when mated with a horse gives birth to an infertile mule.

Saying they are not descended from wolves is total rubbish - all dogs are descended from wolves! How can they be "distinct from dogs" when they clearly are dogs? They come in all colors: tan, black and tan, black and white, just like domestic dogs.

It is accepted that dingoes were brought here by Asian seafarers five thousand years ago. It cannot be a separate breed. Some European breeds were brought to distant lands centuries ago with no further input from European stock and they have remained the same.

There is not much doubt that academics are for the most part "dreamers'. They do not do much that is practical. Dr Crowther is "on" something, or should be!

New Prehistoric Crocodiles Found

A new type of crocodile now extinct has been found in northern Africa. It had three sets of fangs like wild boar tusks for killing other animals. Another kind of crocodile was found nearby. This one used a flat, wide snout to catch fish. A third species of crocodile also located close by was only three feet long. This had "buckteeth" for eating plants. It was a rich find with two other known kinds of crocodile being dug up there.

The National Geographic Society sponsored the successful project. The new crocodiles show that the region had unique animals 100 million years ago. much different than in surrounding regions. These reptiles could run along at quite a fast pace then dive into the water and swim off. Unlike modern crocodiles which have legs on the side of their bodies these had longer legs set underneath. Luckily there were no people around for them to chase and eat.

The three new species are as follows:

1) BoarCroc (Kaprosuchus saharicus) 20 feet in length with three pairs of fangs sticking out of the side of their mouths like a warthog.

2) PancakeCroc (Laganosuchus thaumastos) again 20 feet long with shorter legs, laid in wait for fish grasping them with spiked teeth set in flat wide jaws in a head 3 feet long.

3) RatCroc (Araripesuchus rattoides) 3 feet from nose to tail, had buckteeth and dug for plants and grubs.

Kiwi Came from Australia

Three years ago a fossil was found at st Bathams in New Zealand. The record books now have to be rewritten. It seems the fossil is an ancestor of the Kiwi and it indicates that it was related to the Australian emu. This undermines the premise that the kiwi is a solely New Zealand bird. After all it is the national symbol.

You see, the emu relative could fly and it flew to New Zealand. It was a tiny bird compared to the kiwi. The enormous egg that kiwis lay evolved. It was not "handed-down" by the giant Moa. Eggs began to get larger in birds during the Miocene.

The theory that the kiwi originated in Australia was commonly held before this fossil find. It was believed to have got to New Zealand when the country was joined to Australia on Gondwanaland, but his view has been put to rest.

Most New Zealand birds got bigger over time. This was not unusual. The kiwi evolved from the earlier tiny ancestor. Discovery of this 20 million year old fossil was pure luck. It is the oldest fossil ever found in New Zealand.
