Pheidole Ants Rule the World

Man is not the only animal to dominate the Earth. Pheidole ants have spread over all the livable continents. They are so common that a walk in a tropical forest means some are killed by just stepping forward.

There are 1,200 species of the genus Pheidole. Each has developed to exist in a particular niche of the ecosystem. In a study of 300 species it has been found that certain species evolved similar characteristics independently.

Species proliferated dramatically - from one to 600 species in the Americas. The evolutionary goal was to dominate all niches, first in the New World then in the Old. Expansion across one was independent of the other. Evolution took its own course.

Ants are essential for healthy ecosystems. They aerate the soil, disperse seeds and help move nutrients. In biomass they equate with all vertebrates. Their study is indeed important

Earth's Oldest particle Found in Western Australia - a Zircon Crystal

Everyone knows that Australia is old. Just how old has been defined by science - A zircon crystal on a Western Australian sheep station is the oldest piece of planet Earth. It is 4.4 billion years old.

Tests were done to determine the crystal's age. The rate of decay of uranium against the constant lead showed how old it was. This was confirmed by atom-probe tomography where the mass of lead atoms is measured.

The zircon particle was created on the Earth's crust soon after the planet formed. And the Earth was not a violent place until much later. Water was already present and there is a high probability that life began at this time. The Hadean eon as this period is called in now a misnomer because it means Hadean the god of hell.

Proof of life is unlikely. Science is not advanced enough yet to fully examine this period. Very little can be identified as originating in this period of the Earth's development.

Tranferring Human Minds to Robots Is a Pipe Dream

Some people assume too much. This applies to the scientific sphere where people can "get ahead of themselves" and make claims about achievements that are only in the "possible" stage. Science is advancing very fast, but some things are still out of reach. People in positions of power due to wealth or public office can make the wrong decision.

A group of 100 scientists have been put together by Dmitry Itskov a Russian entrepreneur to download, or upload depending how you look at it, human minds into robots. This is fairy tale stuff. They expect to complete this within 10 years. This is probably at least 30 years away.

These human/robot "things" Itskov has called Avatars. He claims it will mean immortality for humans who agree to have their minds "implanted" into robots. This is a silly point of view. Unless consciousness is transferred as well there is no immortality. Claims that consciousness will be transferred with the mind are nonsense. Neither scientists nor theologians know what consciousness is anyway.

The idea has of course been taken from the movie Avatar. Why Itskov should depart from the script and presume consciousness can be moved with the mind but the body must die is not clear. In the movie humans return to their bodies after cohabiting alien bodies on a colonized planet.
