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. ✴ Evolution by Ty Buchanan ✴ http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml ...

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. ✴ Evolution by Ty Buchanan ✴ http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml ...

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 ...

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...
