Phosphorus plays a crucial role in life chemistry. Phosphates serve as the backbone for all nucleic acids and are the major repository of chemical energy for metabolism. The human body contains about 11,000 parts per million of phosphorus by weight.
Mass Extinctions/ExtinctionsA Family Breakup Kills the Dinosaurs

4/1/2001 A rising challenge to Christianity, both within and beyond the borders of America, springs from the popular obsession with UFOs (unidentified flying objects) and ETI (extraterrestrial intelligent life). Designed to Live, Designed to Die
1/1/2008 "Why don't we see new species emerging now?" Charles Darwin faced this question nearly 150 years ago when he proposed the theory of evolution. His answer–all Earth's habitats are full. Extinction Risks and Speciation Models
When human beings first arrived on the terrestrial scene, more than... Extinction Risks For Birds
By Hugh Ross One of the complex challenges facing evolutionists can be described in simple terms. It is the problem of time. For naturalistic evolution to work, the rate of speciation (introduction of new species) must, by nature alone, exceed the rate of extinction. Observed reality says it does not. In fact, extinction is accelerating (for some obvious reasons) while speciation has virtually stalled. Gamma Rays Burst Biological Evolution
1/1/2003 The energy released during a gamma ray burst strains the imagination. With the power of 10 billion billion suns, gamma ray bursts are the most brilliant photon emitters in the universe. By comparison, supernovae emit (at peak) the energy equivalent of 100 billion suns. If such a gamma ray burst occurred closer than millions of light years away and lasted longer than a few minutes—or in some cases, milliseconds—humanity would be wiped out. Rapid Post-Flood Speciation: A Critique of the Young-Earth Model
8/25/2004 Creationists disagree on the extent of Noah’s Flood. The main reason young-earth creationists insist the Flood was a global event is their model demands it. The Flood is the mechanism they use to explain the earth’s geological features. Rather than forming over millions or billions of years as most scientists believe, young-earth creationists maintain the earth’s features are the result of global floodwaters and processes that accompanied the Flood, like erosion, volcanism and tectonics. The Dark and Bright Sides of Cosmology
10/1/2007 Astrophysics has its ironies. Here’s one: Studies of the brightest galaxies in the universe led to the discovery that 99 percent of all matter is "dark matter".1 But matter is only part of the universe (about a fourth). The rest is energy. Adding irony to irony, research focusing on the brightest stars in the universe shows that "dark energy" is far more abundant than dark matter, making up most of the rest of the universe. Despite its often negative connotation, this "darkness" is not a bad thing. Mass Extinctions/ExtinctionsMass Extinctions/Extinctions |
