Premiered This Day: The Creature Walks Among Us
Back on this day in 1956 the second sequel to The Creature From the Black Lagoon debuted. It's long been considered the weakest film in the trilogy, and it's hard to argue this given that they drag The Creature out of the Amazon, burn him in a fire, and convert him into an air-breathing humanoid with no hope of ever returning to the lagoon. But, when viewed today, the film reveals some deeper tones than I'm sure were originally intended.
The plot and language of the film can now be taken to speak directly to the hot-button topics of genetic manipulation of animals and foods, and man's destructive meddling with nature leading to accelerated rates of extinction. The movie moves beyond being a simple “monster on the rampage” story and actually has some pointed comments to make about science and politics. It's well worth watching on one of those upcoming hot, humid summer nights.

Born This Day: Willi Hennig
From the Willi Hennig Society :
Hennig (April 20, 1913 – Nov. 5, 1976) is best known for
developing phylogenetic systematics, a coherent theory of the investigation and presentation of the relations that exist among species. Contrary to the position generally held during his time, Hennig viewed historical inference as a strictly logical and scientific endeavor. He first summarized his ideas in 1950 in German which became more widely known with the publication of the English revision, Phylogenetic Systematics (Hennig, 1966).

Major Hennigian principles are:

Major Hennigian principles are:
1. Relationships among species are to be interpreted strictly genealogically, as sister-lineages, as clade relations. Empirically, a phylogenetic hypothesis may be determined.More info about Henning HERE. photo.
2. Synapomorphies provide the only evidence for identifying relative recency of common ancestry. Synapomorphies are understood to be the shared-derived (evolved, modified) features of organisms.
3. Maximum conformity to evidence is sought (his auxiliary principle). Choice among competing cladistic propositions (cladograms) is decided on the basis of the greatest amount of evidence, the largest number of synapomorphies explainable as homologues.
4. Whenever possible, taxonomy must be logically consistent with the inferred pattern of historical relationships. The rule of monophyly is to be followed, thereby each clade can have its unique place in the hierarchy of taxonomic names.
Born This Day: Sir William Logan
From Today in Science History:
Logan (April 20, 1798 – June 22, 1875) was a Canadian geologist dubbed the "Father of Canadian Geology."
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 (1842-69) of the new Geological Survey of Canada, its geology was virtually unknown. He produced the monumental Report on the Geology of Canada (1863) which recorded 20 years of research, fieldwork, plotting maps, preparing reports, and examining fossil and mineral specimens.

Born This Day: Noble Johnson
“Meanwhile, the light-skinned Noble Johnson (April 18, 1881 – Jan. 9, 1978) was heavily made up for his role as the village chief [in 1933's, KING KONG]—he was a leading black actor of the era (known as “America’s premiere Afro-American screen star” in the black press) and therefore worth the extra consideration. Johnson, an ex-cowboy, horse trainer, and boxer, had quite a resume before portraying the Chief of Skull Island.
He was a student of all aspects of movie making from directing to distribution, and instrumental in the 1916 formation of the Lincoln Motion Picture Company, created to produce what were called “race movies.” Johnson left the company after it had released three films, rumored to have been “encouraged” by Universal to do so or lose any opportunity for parts at the bigger studio.
Johnson - a childhood friend of Lon Chaney - portrayed a variety of ethnicities in his long career; one of the few black actors of Hollywood’s early era to be allowed any diversity in roles.” From Kong Is King.net

Died This Day: Edward Drinker Cope
Art © Mark Schultz
"What truly assured Cope's (July 28, 1840 – April 12, 1897; above right) place in the history of paleontology and even eclipsed his science was his bitter feud with Yale University paleontologist O.C. Marsh (above left).Read about Cope HERE.
What began as a friendly rivalry in the late 1860s, broke out into all out war in 1872 and then raged on until Cope's death in 1897.
Both Cope and Marsh were recipients of family fortunes and they used their wealth to discover new fossils and to reconstruct ancient life. This scramble literally propelled American science into the forefront of paleontology."

Tyrannosaur Feeding Behaviour
The role of the neck in the feeding behaviour of the Tyrannosauridae: inference based on kinematics and muscle function of extant avians. 2014. Snively et al. J. Zool: 290–303
Abstract [edit]: Tyrannosaurid necks were strong and powerful instruments for wielding the jaws during feeding. Hypotheses of tyrannosaurid neck function are here grounded by observations of neck morphology and function in extant archosaurs.
Respectively derived morphologies in birds, crocodilians and tyrannosaurids compromise inferences for some muscles. However, alternate reconstructions indicate that tyrannosaurid neck muscles combined the robustness of crocodilian musculature with the functional regionalization seen in birds.
Electromyography of the M. complexus in chickens strengthens inferences about its function in both dorsiflexion and lateroflexion in extinct dinosaurs, and further suggests that it imparted roll about the longitudinal axis in concert with the actions of contralateral ventroflexors.
Videography of extant raptors reveals the involvement of the neck when striking at prey and tearing flesh, and reconstructed tyrannosaurid musculature indicates capacity for similar neck function during the feeding cycle.
As for birds, muscles originating in the anterior region of the neck likely stabilized the head by isometric or eccentric contraction as tyrannosaurids (and other large theropods) tore flesh by rearing back the body through extension of their hind limbs.

It's always nice when a paper you've forgotten about gets published!
Published This Day: The DNA Double Helix
From Today in Science History:
On this day in 1953, the journal Nature published a paper from Francis Crick and James Watson, titled Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid, in which they described a double helix structure for DNA.
