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.

Australian Binge Drinking Problem
Australia is a society that "molds" itself around a culture of high alcohol consumption. Other countries also have this problem. Germany, Ireland, Scotland and England also have a reputation for excessive drinking behavior. None, though have the strong established culture as that in Australia.
The young learn from the old. Australian youth spend their weekends in a blur of binge drinking. Their parents have openly consumed alcohol at parties, barbecues and in pubs, since the youth were toddlers. And in Australia, children can be brought into pubs.
Cultural change is called for by the federal government. However, cultural norms of behavior are nearly impossible to change unless people feel a real crisis. The Ebola catastrophe in Africa have forced citizens to change their burial habits. Unfortunately, Australians do not take the alcohol crisis seriously. They think it does no apply to them.
The intention to charge mothers with a crime for damage to their unborn babies through heavy alcohol consumption is a step in the right direction. It could also be extended in the future to cover the obesity crisis as well. Regrettably, laws have not stopped illegal drug use. People are stubborn. It is like believing that you can change someone - individuals can change in the short term. They go back to their old ways in the long run.
