First RNA Formed in Freshwater Pools Near a Volcano

Chemistry: Life began near an active volcano in a freshwater puddle.
Use your imagination and assume that life began in a puddle of fresh water near an active volcano. Molecules begin to "see" each other and unite into a larger whole. They become membranes, the envelopes of future life. Like a chicken's egg the membrane shell is the holding structure where chemicals are assembled for incubating lifeforms.

RNA was the first significant biological molecule. This has a basic form of repeating subunits. A simple molecule perhaps. but difficult for a primitive Earth to "create". Yet it came into existence. Membrane were required for chemicals to grow into RNA. The fatty, lipid molecules in membranes formed easily. Lipids assist the building of RNA, then it forms a protective coating. This was the first primitive cell.

As soon as some RNA replicated, lifeforms began to evolve becoming more complex. This occurred in fresh water which was heated and cooled probably close to a volcano. Cycles of changing temperatures caused chemicals to move around and become concentrated which was necessary for molecular synthesis to take place.

New Lizard Found Near Perth

Despite the idea that everything is known about everything, the area of discovery is still wide open. Just outside of Perth in the sand dunes a new species of lizard has been found. It has been given the name Ctenotus ora.

There are concerns that it will not be around for much longer. New housing is encroaching upon the coastal plains skink's land. The lizard was identified during an Australian National University study into biological diversity in the Perth region.

Just how many of the lizards are out there is not yet known, so their prospects of survival is still an open question. The area of sand dunes where they live is getting smaller. Unless the state government steps in to stop it, urbanization will see most of the dunes concreted over.

The southwest of the state has not been explored in great depth. Other new species are probably waiting to be brought to light. Though people have been there a long time, concerns about work and shelter have been the priority not biological research.
