Artefacts ‘alter migration story’


A research team reports new findings of stone age tools that suggest humans came “out of Africa” by land earlier than has been thought.

Geneticists estimate that migration from Africa to South-East Asia and Australia took place as recently as 60,000 years ago. But Dr Michael Petraglia, of Oxford University, and colleagues say stone artefacts found in the Arabian Peninsula and India point to an exodus starting about 70,000 to 80,000 years ago – and perhaps even earlier. Petraglia, whose co-workers include Australian and Indian researchers, presented his ideas at the British Science Festival, which is hosted this year at Aston University. “I believe that multiple populations came out of Africa in the period between 120,000 and 70,000 years ago,” he said. “Our evidence is stone tools that we can date.” http://www.bbc.co.uk/news/science-environment-11327442

James Watson and Francis Crick
James Watson (left) was only 24 when together with Francis Crick (right) he published the paper that first described the structure of DNA
“Newly-found letters of the British scientists who discovered the structure of DNA highlight tensions around this major scientific breakthrough.” http://www.bbc.co.uk/news/science-environment-11438569

Great ‘real’ story.
“Tiny tubes thought to have been etched into South African rocks by microbes are at least 3.3 billion years old, scientists can confirm.” http://www.bbc.co.uk/news/science-environment-11525674 The dating work is reported in Earth and Planetary Science Letters.

It is a follow-up study to the University of Bergen team’s discovery of the microscopic tunnels and pits first published in 2004.

The earliest plants to have colonised land have been found in Argentina. The discovery puts back by 10 million years the colonisation of land by plants, and suggests that a diversity of land plants had evolved by 472 million years ago. http://news.bbc.co.uk/earth/hi/earth_news/newsid_9079000/9079963.stm

Benoit Mandelbrot, who discovered mathematical shapes known as fractals, has died of cancer at the age of 85.

“Mandelbrot, who had joint French and US nationality, developed fractals as a mathematical way of understanding the infinite complexity of nature. ” http://www.bbc.co.uk/news/world-europe-11560101

“A tiny faint dot in a Hubble picture has been confirmed as the most distant galaxy ever detected in the Universe. This collection of stars is so far away its light has taken more than 13 billion years to arrive at Earth.” http://www.bbc.co.uk/news/science-environment-11580789

Audio slideshow: Jurassic woman – “She survived a lightning strike as a child, and it’s suggested that she inspired the tongue-twister “She sells sea shells” – but it was her prolific work on the Dorset beaches, known now as the Jurassic Coast, that earned Mary Anning her place in scientific history. Her fossil discoveries 200 years ago near Lyme Regis – are being celebrated by the Royal Society, The Natural History Museum and the town’s museum. With novelist Tracy Chevalier, who has written extensively about the early fossil-hunter, take a look back at Mary Anning’s remarkable life.” http://www.bbc.co.uk/news/science-environment-11590505

Early date for Chinese human fossils – “Modern humans could have reached East Asia much earlier than believed, according to new evidence. An international team analysed fossil teeth and part of a jaw unearthed in southern China in 2007. In the journal PNAS, the scientists say the fragments belonged to a “modern” human who lived 100,000 years ago.” http://www.bbc.co.uk/news/science-environment-11618814

“Palaeontologists have identified the oldest known dinosaur embryos, belonging to a species that lived some 190 million years ago. The paper stated that the rather awkward body of the embryos suggested that just like humans, the hatchlings would have required parental care – and if in this case, it would be the earliest known example of parental care.” http://www.bbc.co.uk/news/science-environment-11734616

About luckyme0

My First family, second marriage, bringing up my 18-year-old twins, boy, and girl. I am a third generation Humanist, who has some old handwritten information and notes; collected over many years. Someone may find the articles interesting, or helpful. They could bring back a little ‘reality’, after being ‘shocked’ and ‘brainwashed’, by some malicious group, or institution (REBT Therapy). People should know better, than to do this, to our very young, and the ‘obviously’ vulnerable! Go to easily accessible, non-superstitious knowledge that is not charlatanism! https://charleslizzy.com/2011/08/06/independent-schools-inspectorate-isi-marketing-spirituality-buzzword-or-maybe-even-for-you-to-shiver-at-the-something/ The blog has given me an incentive to order my thoughts, learn, and read up again, after a few non-thinking years of (very silly) imagination and passion. Why not, get your own key to a ‘door’, customise it to suit you, and it can be, all of your very own! Don’t believe, or be led by someone else’s; inherited, stupid, and a very likely (past, and not of today’s) ‘totally preposterous reality’s’. Only some interest in the ‘really big questions’, keeps life above the level of a farce, and very little else! KEEP THINKING! Some of the posts may need some correcting. Interests: REBT Counselling, Atheism, Secularism, Humanism, Psychology, Reading, Popular Science, School Ethos, Philosophy, History, Family, Parenting, Psychology, Horse Riding, Sailing, Rescue Boat Driver, Skiing (Teppichswinger), TV Documentaries, Motorbike Cross Country Riding, Volunteer Sports Stewarding, Writing, Primitive Man, Pre-history, Social Anthropology, British Humanist Association, BHA, Meaning of Life, The Big Questions, Where am I, What am I, Why am I, Hippie Love, Knowledge, Education, Globalisation. Favorite quote: “The world belongs to those who, at least to some degree, have figured it out.” Carl Sagan, ‘The Demon Haunted World’, ‘Contact’, and other famous books DVD ‘Cosmos’. The warning of another and horrendous, “Age of Superstition”. “Isn’t there something deeply absurd in the presumption that children ought to inherit beliefs from their parents. It can be deeply damaging, even lethally divisive. A ‘them’, with an ‘against us’, mentality” – Professor Richard Dawkins. “The will to believe is stronger than mere reason in the vast majority of people” – Dr J.Brown, Army Psychologist of the 1960′s. Humans will believe in almost anything, in fact, they seek it! Why? “98% of us, trained to be just good consumers, let’s train our children to be the 2% who have their very own creativity and discernment”; quote by a famous surreal artist. “The lack of reason brings forth monsters”. “Global interconnectedness is lethal against mass religion, nationalism, racism, and other destructive memeplexes. Let us connect everybody they hate it in restrictive regimes”; from the ‘meme learning group’, Richard Brodie’s book, ‘Virus Of The Mind’ (Richard Brodie a designer for ‘Microsoft Word’). Following on, J.Bronowski, and ‘The Ascent Of Man’ TV series, and a book http://www.bbcshop.com/science+nature/the-ascent-of-man/invt/9781849901154/ with the last DVD in this series, ‘The Long Childhood’ being especially revealing. ‘Prehistory’ and the ‘Making of the Human Mind’ by Colin Renfrew, with P.Wilson’s, ‘The Domestication of the Human Species’, and Nigel Spivey’s, TV series and book, ‘How Art Made The World’, offers some further explanations.
