Promoter Regions Explain Ape Human Difference

Promoter regions explain ape human difference, reports an article in ScienceNOW 13 August 2007. Although chimp and human genes are claimed to be 99 percent the same you don’t have to be a biologist to see that chimps and humans are very different. Way back in 1975 Allan Wilson of the University of Wisconsin suggested […]

Polar Bears Were Irish

Polar bears were Irish, according to articles in BBC News 7 July 2011 and ScienceDaily 8 July 2011. Scientists in the UK, Ireland and USA have studied mitochondrial DNA extracted from the teeth and skeletons of 17 Brown Bears that were found at eight cave sites across Ireland. Mitochondrial DNA (mtDNA) is genetic material carried […]

Pigeon DNA Proves Darwin Right

“Pigeon DNA proves Darwin right” claims Nature News 31 January 2013 in a genetic study of pigeon breeds also reported in ScienceNOW 31 January 2013. Charles Darwin spent many years breeding many varieties of pigeons, and wrote about them in Origin of Species. According to Nathan Young, an evolutionary biologist at the University of California, […]

Location Matters for Genes

Location matters for genes, according to a report in New Scientist, p12, 15 September 2001. At a meeting of the British Association Wendy Bickmore explained that our genes are organised so that the most active genes are in the centre of the nucleus and the less active parts of the genome arranged around the outside.

Lactose Tolerance Evolved Three Times

Lactose tolerance evolved three times, according to articles in ScienceNOW 11 December 2006 and Science, vol. 314, p1672, 15 December 2006. Lactose tolerance is the ability to digest milk in adult life, and depends on the activity of an enzyme named lactase that breaks down lactose, the sugar in milk. In most of the world’s […]

Junk Generated RNA

Junk generated RNA “astonishes” scientists, according to a report in New Scientist, 21 February 2004, p.10. When the information encoded on DNA needs to be used to make proteins, the information is copied onto a similar molecule called RNA. However, not all DNA codes for proteins and it has been assumed that the “non-coding” DNA, […]

Jumping Genes Make Brains Unique

Jumping genes make brains unique, according to reports in ScienceNOW 15 June 2005, Nature Vol 435, p903 and New Scientist 18 June 2005, p21. Jumping genes are pieces of DNA that can spontaneously move from one place in the genome to another. When they insert themselves into a new part of the genome they can […]

Indian Frog Living Fossil

Indian frog is a living fossil, as reported in Nature vol. 425, p711, 16 October 2003. Scientists have analysed the DNA of a strange purple burrowing frog recently discovered in India and found it is similar to some frogs that are only found in the Seychelles Islands in the middle of the Indian Ocean. The […]

Hybrids Produced New Species

Hybrids produced new species, according to a report in New Scientist, 16 August 2003, p12. A team of scientists led by Loren Rieseberg of Indiana University, Bloomington USA studied the genes of five species of sunflower and came to the conclusion that three of them were hybrids descended from the other two. The “hybrid” species […]
