POPSAccuracy of radiometric dating an earlier clip got me looking for resources on the internet to explain simply, yet completely, the underpinnings of radiometric dating. www.pbs.org/evolution provides a good starting point for many such references. there is a religious tract on the internet that makes many claims about the inaccuracy of radiometric dating methods and the infallibility of the bible as a historical record. the link in this clip addresses some of its primary claims.

POPSFossils tell of mass exodus from sea Creatures could develop some protection from the sun in the water, but the land was wide open, and predators were yet to get anywhere the efficiency of ocean based predators. They can understand why shelled arthropods had the protection to survive, but can't understand the survival of soft bodied things like worms and Molluscs? then perhaps they can explain why a slug like creature evolved a shell and branched unto the Snail genotype. i don't imagine life is safe anywhere for exposed slugs and worms, and solar radiation, particularly UV Light can accelerate development. and change. Perhaps they were moving to the place that was the least dangerous.

POPSFossil Reef found in Aussie outback So now they think Animal life evolved 80 million years earlier than we had calculated. clearly 'Scientific' discoveries are too often base with too little evidence. one of the Basic Principles of "science' is the development of a method and a control where a method can be repeated in an attempt to get similar or 'Identical'- through the imposition of specific qualifications. this can be difficult when most natural situations are unique, or 'one offs' There's generally no harm in 'looking', we just have to be careful the way we describe what we find

POPSJesus Horses and Sarah Palin Sarah "Speaking in Tongues" Palin explains how she believes that dinosaurs and man lived together. This is precisely why the taboo of not discussing one's religion is wrong. This woman's viewpoint needs to be brought out and examined in the light of day. She holds ideas that have consequences in an increasingly technological world. By her own statements, she clearly doesn't have a clue what's going on.

POPSessay on creationism vs evolution long essay talking about how many who defend evolutionary theory need to rethink their approach because often their responses to creationists are inflammatory (thus hundering honest open debate) and/or do not reflect actual science. the essay deals specifically with the origin of life, and is a response to a couple other essys/blogs that are linked to.

POPSWere Ancient Viruses a Key to Human Evolution? Heidmann believes that without endogenous retroviruses mammals might never have developed a placenta, which protects the fetus and gives it time to mature, which eventually led to live birth, one of the hallmarks of human evolutionary success over birds, reptiles, and fish. Eggs cannot eliminate waste or draw the maternal nutrients required to develop the large brains that have made mammals so versatile. “These viruses made those changes possible. It is quite possible that, without them, human beings would still be laying eggs.”

POPSWere Ancient Viruses a Key to Human Evolution? These viral fragments are fossils that reside within each of us, carrying a record that goes back millions of years. Because they no longer seem to serve a purpose or cause harm, these remnants have often been referred to as “junk DNA.” Although many of these evolutionary relics still manage to generate proteins, scientists have never found one that functions properly in humans or that could make us sick. That is until Thierry Heidmann who runs the laboratory at the Institut Gustave Roussy, on the southern edge of Paris, brought one to life. Heidmann long suspected that if a retrovirus happens to infect a human sperm cell or egg, which is rare, and if that embryo survives—which is rarer still—the retrovirus could have the evolutionary power to influence humans as a species becoming part of the genetic blueprint, passed from mother to child, and from one generation to the next, much like a gene for eye color or asthma.

POPSBroon modelling for Michaelangelo.
Put maer Gin in yer tonic, Gordin. Labour Cullodened in Glasgow east. Within the next eighteen months that will be the same in Blackpool. Why? Last night I talked to a young man who echoed the derision of youth and the enthusiasm of not having lived through past Labour miseries on the late 60's and mid 70's. With prospective Conservatives swanning it in deepest Rwanda, now is an ideal time for the youth of the region to kick these fossils in the dangly bits. Go for it Ben. If you can't find a decent Party to adopt you, follow the lead of the Independent Doctor in the Forest of Dean and go it alone. I think the Conservatives have dropped a clanger with their nominee and I will be doing everything in my power to explain why to the electorate. Already the hierarchy of the local CP(Conservative Party) refuse to debate their situation with anyone not in their local party. Where was that article that say it takes £20K to get a nomination as a CP prospective candidate?

POPSDinosaurs Diversified Over Time, not Suddenly During this epoch of riotous biodiversity, flowering plants, social insects, butterflies, modern groups of lizards, mammals, and possibly birds, too, all emerged. Some experts have suggested that dinosaurs were also part of the show, as so many weird fossils, such as duckbilled hadrosaurs, horned ceratopsians, pachycephalosaurs and other wonders, date from this time. But a new study, published on Wednesday in a British journal Proceedings of the Royal Society B, says that dinosaurs were less than a sideshow in the DNA spectacular. Researchers led by Graeme Lloyd of the University of Bristol, western England, devised a "supertree" of dinosaur evolution, patiently analyzing how more than 450 species -- about 70 percent of the known finds -- developed.

POPSDino diversity earlier than first thought Maybe there is the idea that species including the dinosaurs were trying to deal with conditions brought about by the meteor, so many adaptations arose, but nature loves nothing more than competition, even when times are good.

POPSFlatfish caught evolving, thanks to its roving eye Now Friedman reports finding two different missing links. They are fossil fish with their eyes in different places on the two sides of their skulls - one in the normal position and one closer to the midline (see Diagram). One is Amphistium, a previously described genus found in several fossil deposits in Europe, in which the asymmetry went unnoticed because in fish fossils only one side of the animal is generally preserve. The other is Heteronectes, a new genus. At 10 to 20 centimetres long, the specimens were clearly adults and not larvae in which the eyes were migrating
