  1. imo it doesnt change anything. because we now have terms like past, present and future. we also record time chronologically etc.
  2. A tiny, furry-tailed creature is the most complete picture yet as to what the ancestor of humans once looked like. These new findings also suggest this forerunner appeared shortly after the catastrophe that ended the age of dinosaurs, scientists added. http://news.yahoo.com/meet-mama-first-ancestor-placental-mammals-revealed-191137721.html
  3. http://www.foxnews.com/science/2013/01/21/doubling-down-four-stranded-quadruple-helix-dna-discovered/ 60 years after scientists first described the “double helix” shape of human DNA, the chemical code of life, scientists have discovered the first quadruple helix -- and it may help them prevent the runaway cell proliferation at the root of cancer. "It's been sixty years since its structure was solved but work like this shows us that the story of DNA continues to twist and turn," said Julie Sharp, senior science information manager at Cancer Research UK. 'The story of DNA continues to twist and turn.' - Julie Sharp, senior science information manager at Cancer Research UK The research, published Monday in the science journal Nature Chemistry, shows clearly a four-stranded DNA structure that the scientists dubbed a “G-quadruplex.” The name comes from the building block guanine, one of the chemical bases that form DNA, along with adenine, cytosine, and thymine (usually abbreviated to their first letter). By targeting these DNA oddities with synthetic molecules that trap and contain them -- preventing cells from replicating their DNA and consequently blocking cell division -- it may be possible to halt the spread of cancer, the researchers said. "We are seeing links between trapping the quadruplexes with molecules and the ability to stop cells dividing, which is hugely exciting," said professor Shankar Balasubramanian from the University of Cambridge's Department of Chemistry and Cambridge Research Institute, whose group produced the research. "We've come a long way in 10 years, from simple ideas to really seeing some substance in the existence and tractability of targeting these funny structures," he told the BBC. "I'm hoping now that the pharmaceutical companies will bring this on to their radar and we can perhaps take a more serious look at whether quadruplexes are indeed therapeutically viable targets Read more: http://www.foxnews.com/science/2013/01/21/doubling-down-four-stranded-quadruple-helix-dna-discovered/#ixzz2IdhuXA3Q
  4. i have been told that certain fruits and vegetables are male/female is there any truth to this?
  5. would this also pertain to a different phenotype
  6. how does infra red light work ? we can't see that shift normally right ? what if i made a full body suit made of infra red, would yall be able to see me ?
  7. actually found it on another site but i see your point and thanks
  8. actually this is something i came across online (in reference to the theory)
  9. okay someone gave me this answer would you agree with this : There is a theory that peoples that lived in grassland savannas tend to have more intricate musical patterns than peoples that lived in other terrains. The thought being that grassland and lowland savannas by nature tend to allow sound to travel further and more accurately. This is thought relevant due to hunter gatherers leaving the homesite further and further away and over time using chants, percussions and "music" as a communicative network with the homesite.. Over time, this disposition toward chants, pervussions and music proves beneficial and is made more complex to communicate more complicated messages...thus over time providing survival value that can be refined and passed fown through darwinian and mendelian mechanisms.
  10. AbiogenesisDo Evolutionist believe in Abiogenesis aka Spontaneous Generation? If so, explain why.
  11. ???? also also another good question about sound is why are asian people usually better at identifying specific musical notes than other peoples. i know its related to pitch and that asian people seem to use pitch a lot more in their speech to stress different syllables
