The Theory Of The Glacial Sarasvati Has Been Given A Quiet Burial

Something significant went unnoticed and unreported amongst all the hoopla surrounding the recent paper on Harappan civilization and its link to climate change. The theory of the glacial Sarasvati got dumped. The paper does not even mention it as a possible reason for the reduced water flow in the Ghaggar. Based on its geographic description in the Rig Ved the Ghaggar has been equated with

Iron Fertilization Won’t Work in Equatorial Pacific, Study Suggests

Over the past half-million years, the equatorial Pacific Ocean has seen five spikes in the amount of iron-laden dust blown in from the continents. In theory, those bursts should have turbo-charged the growth of carbon-capturing algae, but a new study shows that the excess iron had little to no

The bit about early life having a devastating environmental impact is just a shot at the greenies.  What goes around comes around, there isn't anything that the Earth hasn't experienced before, many times.  Digression:  We have no logic that takes us from organic molecules to DNA.  For a while I thought about Galactic Seeders, but now I believe in my "Theory of Evolution of Primordial

Published This Day (1868): Variation of Animals and Plants under Domestication by Darwin

From Today In Science History: In 1868, Charles Darwin's book - Variation of Animals and Plants under Domestication - was published. He was 58. It is probably the second in importance of all his works. This was a follow-up work, written in response to criticisms that his theory of evolution was unsubstantiated. Darwin here supports his views via analysis of various aspects of plant and

Wallace (Jan. 8, 1823 – Nov. 7, 1913) was a British naturalist and biogeographer. He was the first westerner to describe some of the most interesting natural habitats in the tropics. He is best known for devising a theory of the origin of species through natural selection made independently of Darwin. Between 1854 and 1862, Wallace assembled evidence of natural selection in the Malay

Hutton (June 3, 1726 - March 26, 1797) is considered to be the father of modern geology. He is accredited with proposing that observed geologic processes have been occurring at a uniform rate since the creation of earth, also know as the theory of unconformities. This led to his controversial suggestion that the earth is incredibly old. Hutton began to notice geologic processes on his land

On this day in 1967, the governor of Tennessee signed into law the repeal of the 1925 state law prohibiting the teaching of evolution. The original law had made it "unlawful for any teacher in any of the Universities, Normals and all other public schools of the State which are supported in whole or in part by the public school funds of the State, to teach any theory that denies the story of

Two important new palaeobiological hypotheses regarding diplodocids

The first hypothesis is that, contra Elk (1972), all Brontosauruses were rather fat at one end, then much fatter in the middle, then thin at the other end. The second theory is that Diplodocus was dumb. Evidence is here presented in the form of an important new life restoration by Matthew Taylor. References Elk, Anne.

Patrick Matthew (1790-1874) was a Scottish landowner with a keen interest in politics and agronomy who also came up with the concept of 'evolution by natural selection' 27 years before Charles Darwin did.Matthew's version of evolution by natural section captures a valuable aspect of the theory that isn't so clear in Darwin's version - namely, that natural selection is a deductive certainty

He began is career making geologic maps of coalfields in Wales, noting the relationship between the underlying clay layers and fossil tree roots with local coal beds. This substantiated the theory that coal beds are formed in place. When he began as director

This whole thing is quite relevant today, since the usgus has got everybody convinced that it is shallow faults and injection volume that is driving this whole thing.  Thus, Kansas and OK are reducing volumes.  The next big earthquakes will blow that out of the 'water'. So, we look in detail at my 'straw dog' principles, or working hypothesis.  I've almost promoted all this to a theory,

Last night we played dominos.  Somebody remarked that the failure of the Mt Polley tailings facility was like a line of dominos standing on end and all lined up: push the first one over and it topples the next one that knocks over the next, until they all fall down and flow to Hazeltine Creek.

The partial shell below is likely from an inarticulate brachiopod called Lindstoemella sp.  It came from the Centerfield mbr. of the Ludlowville Fm. near Fayette, NY.  This would have been the top valve of the animal since the bottom valve was likely cemented to a hard surface. It is interesting to note the differences in the rock type of the Centerfield member between two geographically distant locations. Normally I collect fossils from this rock unit that are eroding out of a grey [...]
