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.

Fossil is an Ancestor of Man

We know that we are related to sea creatures. Finding which ones are close ancestors is the problem. Dr Garcia-Bellido holds that odd-looking fossils of Nesonektris had cartilage which has the same structure as the "tails" of human embryos.

Muscles latch on to notochord cartilage. Findings have been published in BMC Evolutionary Biology by universities of Adelaide and South Australia with the South Australian Museum. The University of New England also took part in the research.

The source of the 500 million year old fossil is Kangaroo Island. This region has some of the world's richest fossil beds. vetulicolians lived in the Cambrian period and were filter feeders. Their cartilaged-tails were used for propulsion. This type of connections with humans had been overlooked in the past.

Australpithecus sediba Is Not an Ancestor of Man


The Announcement that skeletons found in South Africa belong to a new species of Man is premature.  They were found in a cave near Johannesburg. The "new species" was named Australopithecus sediba. It was claimed to be the "rosetta stone" into the past. They were also the most complete skeletons ever discovered. The creatures walked upright, had long arms and powerful hands. Unfortunately, they were small brained.

Paleoanthropologists not involved in the find say the name chosen is just a "wastebasket" category. They are not ancestors of Man. Furthermore, some animals in the species could have had larger or smaller brains. It could still be transitional in evolution to Man, but very distant.

It may fit into Homo. Perhaps it is a sister species to Homo habilis. The brain size of Australopithecus sediba is the same as Homo floresiensis, the Hobbit, of Indonesia. The features in sediba are similar to those in other Homo species. Paleoanthropologists put very early finds in Homo. Sediba is not so unique as to have a lineage of its own. Indeed, Australopithecus africanus is older than sediba and africanus does have unique lineage. Sediba is too primitive to be a direct ancestor of Man. Older Homo species have features more like Man than sediba.

Spread of Malaria to Man from Other Apes - Just Theory

Gorillas caused it. Scientists say mosquitoes split into a new form capable of infecting humans when Man and chimpanzees had a common ancestor. This is a myth. It is not based on fact. Bonobos have also been singled out for blame despite no parasites being found in bonobos or western gorillas, though some parasites were found in chimpanzees and eastern gorillas.

Before conclusions can be drawn on such research evidence of this mystery ancestor must be found first. This is all hearsay. How can present day apes be responsible for current malaria infection. Gorillas are only found in very small parts of Africa, not all around the world.

This wreaks of leaps of faith not science. It is no better than religious beliefs based on prophets who probably never existed. It is scientific fact that evil spirits do not cause disease, yet millions of people believe that a man, Jesus, cured illness by casting out spirits.  Note, everyone is entitled to follow a religion.

New Kind Human Found Which Challeges Darwinian Theory

A new find of human remains challenges Darwinian theory. Science was absolutely certain that for the past 80,000 or so years only humans and Neanderthals wandered the earth. First the "hobbit" on the island of Flores was found which showed that other hominids lived almost to the present time in remote parts of the world. Now a new human species has come to light in Mongolia. The DNA from a child's finger indicates a separate species. Denisova is the name given to the new humans after the region where it was found.

For many years it was believed animals with a different number of chromosomes could not interbreed. This premise is now brought into question. Neanderthal DNA has been identified in human DNA. This finding makes the discovery of our origins almost impossible. With no clear distinction between species how do you put them into categories?

Denisova and humans diverted from a common ancestor about a million years ago. Neanderthals and humans separated from their ancestor half a million years ago. If interbreeding was commonplace Man's history will be blurred. The offspring of parents from two types of hominids will carry traits from both variations. Finding remains of distinct species will be more difficult. For the most part, however, bones and fossils of different hominids are being found. Perhaps cross breeding was not the norm.
