And of what is it all made? Without this understanding it is impossible to come to any firm conclusions about how the universe evolved. Protons, Neutrons and Electrons: The Stuff of Life You, this computer, the air we breathe, and the distant stars are all made up of protons, neutrons and electrons. Protons and neutrons are bound together into nuclei and atoms are nuclei surrounded by a full complement of electrons. Until about thirty years ago, astronomers thought that the universe was composed almost entirely of this "baryonic matter", ordinary atoms. WMAP and Dark Matter / Dark energy By making accurate measurements of the cosmic microwave background fluctuations, WMAP is able to measure the basic parameters of the Big Bang model including the density and composition of the universe. 4.6% Atoms. Another Probe of Dark Matter HST Image of a gravitational lens Candidates for the Dark Matter.
Cool Cave Facts. "Leave Nothing but Footprints, Take Nothing but Pictures, Kill Nothing but Time.
" [ About UCG ] [ Scott's Gulf ] [ Caving Safely ] [ Cave Conservation ][ Gallery Underground ] [ The Entrance ] Skip to.... Caves in Human History Human beings have been exploring caves since the dawn of time. In human prehistory, they provided shelter, as well as a canvas on which prehistoric man could paint his desires for a good hunt. Among Stone Age cultures, caves had great ritual significance.
In more modern times, caves have been used for a variety of purposes: refrigerated food storage during pioneer times, saltpeter mining and weapons storage during the 1800s, speak-easies and hideouts for moonshine stills during Prohibition, and dance halls during World War II. Currently, extreme outdoor sports have gained popularity thanks to the "Mountain Dew" mentality of "been there, done that. " Back to the TOP of the page.

CORDIS FP6: New and emerging science and technology (NEST) Home. 29+ Evidences for Macroevolution: the Scientific Case for Common Descent. Volution, the overarching concept that unifies the biological sciences, in fact embraces a plurality of theories and hypotheses.
In evolutionary debates one is apt to hear evolution roughly parceled between the terms "microevolution" and "macroevolution". Microevolution, or change beneath the species level, may be thought of as relatively small scale change in the functional and genetic constituencies of populations of organisms. That this occurs and has been observed is generally undisputed by critics of evolution.
What is vigorously challenged, however, is macroevolution. Macroevolution is evolution on the "grand scale" resulting in the origin of higher taxa. Universal common descent is a general descriptive theory concerning the genetic origins of living organisms (though not the ultimate origin of life). This article directly addresses the scientific evidence in favor of common descent and macroevolution. What is Universal Common Descent? How to Cite This Document. Constellation List.

"Textbooks present science as a noble search for truth, in which progress depends on questioning established ideas. But for many scientists, this is a cruel myth. They know from bitter experience that disagreeing with the dominant view is dangerous - especially when that view is backed by powerful interest groups. Call it suppression of intellectual dissent. Introduction Science is in a state of crisis. In true science, theory always surrenders to the primacy of evidence. But in current mainstream science, the opposite occurs with disturbing regularity. Referring to the fin de siecle "end of science" mentality and the scientific revolutions following it, Robert G. "As we enter the 21st century, science seems poised to execute a similar evolutionary cycle of advancement of their comprehension and relevance.
