  • Aquatic Ape Hypothesis

    The Aquatic Ape Hypothesis By David Shiffman, on September 9th, 2010 Science can often be complicated, which makes a simple explanation extremely appealing. Sometimes, these simple explanations are correct. Sometimes they are spectacularly wrong. One of the most complicated areas of science is evolutionary biology. Describing the origin of current species  is a lot like putting together an enormous puzzle when most of the pieces are missing. A simple explanation for an evolutionary problem would

    WHAT IS ECOSYSTEM An ecosystem consists of the biological community that occurs in some locale, and the physical and chemical factors that make up its non-living or abiotic environment. There are many examples of ecosystems -- a pond, a forest, an estuary, grassland.  The study of ecosystems mainly consists of the study of certain processes that link the living, or biotic, components to the non-living, or abiotic, components. Energy transformations and ecosystem components are the two main topics
