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.

Spiders Eat Fish

It is commonly believed that spiders are land dwelling creatures that eat air breathing prey. However, this is a misconception. New research shows certain spiders eat fish.

These spiders exist on all continents except Antarctica. No less than eight kinds of spider consume fish up to twice their size. they also eat amphibians, mice, bats and birds.

The diving bell spiders lives underwater. Many spiders live on the edge of water bodies and will eat just about anything that can be caught. Some fish they catch are very large indeed. Spiders take the chance of a rough fight because nearly all of a fish is edible.

They hunt by holding on to something solid on the land with two of their rear legs. When a fish actually touches one of the six legs in the water the spider pounces completely leaving the land and bites the fish on the neck.

We do not know everything about nature. Much of the living habits of animals is still unknown. As time goes on and data are accumulated we will know more but never all of it.
