Anthropologists and Archaeologists Anthropologists

many ways. They have taken us back to our most
humble beginnings. They have given us an awareness
of just how far we have come through the
centuries. Archaeology is the investigating of
life by unearthing and interpreting the objects
left behind by earlier peoples and cultures,
dating back to prehistoric times. Anthropology is
the scientific study of hominids, their physical
features, developmen...

Carbon Dioxide Emissions Amount Of Carbon Dioxide

The consequences of global warming have by now
come to the attention of the majority of the
population of the United States of America. The
gradual warming of the earths atmosphere is due to
an increased amount of carbon dioxide released
into it. The burning of fossil fuels, oil, coal,
and natural gas are the main activities that
release carbon dioxide into the atmosphere.
Americans add carbon dioxide to the atmosphere
every time they drive their car, use a chainsaw,
or use electricity produced ...

Soft Bodied Animals Early Cambrian Rocks Large

In Namibia, where the rock record is excellent,
Vendian fossils are followed immediately by
Cambrian fossils, and they may have overlapped
briefly in time. In Siberia, a whole suite of
small shelly fossils appears in the rocks as the
Cambrian period begins, together with sponges of
several different types. Most of the small shells
are tiny cones and tubes that we don't understand
properly, but at least some of them are complex
animals, including the first molluscs. Soon,
archaeocyathid sponges w...

considering that the earth will naturally warm up
again, and when it does that it will warm up a
little more than it was before. But what I think
Dr. Landscheidt is are saying is that it does not
need to be dealt with so fast because the planet
will cool down more. So we can do it slower and
spend less money on it. But we do not know if the
greenhouse effect will overpower the natural
effects. Unfortunately, this scenario of normal

of humanity is as old as its inhabitants. Since
the early 1800 's mankind has narrowed the debate

is returning to religion. Scientists are finding
proof that the universe was created by a Supreme
Being. The word evolution refers to the change of

Newsday Health And Discovery Health And Discovery Years

Fossils are amazing how they are formed. The
process is fossilization. I was surprised to
discover that a series of mistakes must happen in
order for a fossil to be created. First some
living creatures must die and must some how escape
the scavengers that have a roll in the food chain.
The once living has to then become entombed in mud
and sand. The shroud must lie undisturbed for
years so that mineralization can take place in
which the tissue or cast gets filled in with
sediment. Then this body...

the animals in the zoo he is visiting. He implies
his disapproval of these things by using phrases
such as; The apes yawn, and adore their fleas in

In giving to the treatise here announced the name
of an Essay on the Theory of the Earth, the Editor
has taken a liberty that is certainly not
warranted by the original. The title of the French
work makes no mention whatever of the theory of
the earth. The fact is, that M. CUVIER having

of memoirs on the fossil remains of animals found
in the strata around Paris, (of which an account

nuclear fission produces toxic waste, and solar
heaters are not efficient. When compared to other
energy sources, hydroelectricity has fewer
disadvantages and is being explored and widely
used today. Throughout the world an increasing
amount of people are turning towards hydroelectric
power as a new source of energy. Although the idea
of converting water to power might seem simple,

How the Snake Lost Its Legs In the article 'How

the common theory of snake evolution is about to
be questioned. All vertebrates that live on land
whether mammalian or reptilian are known as
tetrapods. In most animals these feet evolved into
other limbs, like arms for humans and into wings
for birds; however, the snake lost its four feet
altogether. The only sign that snakes ever had
four feet is a remaining hip located within the
