Interesting take on the periodicity of species extinction
from the UC Santa Barbara campus;
"Santa Barbara, California - The sixth mass extinction of both plants and animals is underway, scientists say, warning that nearly 50 percent of all species could disappear within the lifetimes of people now living on Earth.
Some species are more critical than others in preserving the functions of ecosystems and scientists researching grasslands around the world have found that the most valuable species are those that are genetically unique.
"The current extinction event is due to human activity, paving the planet, creating pollution, many of the things that we are doing today," said scientist Bradley Cardinale, assistant professor of ecology, evolution and marine biology at the University of California-Santa Barbara.
"The Earth might well lose half of its species in our lifetime," he said. "We want to know which ones deserve the highest priority for conservation." .... etc.
