Rugged star’s nose for fame

-

QUESTION The Sixties U.S. sci- fi series The Invaders starred actor Roy Thinnes. What became of him?

Roy Thinnes was born on April 6, 1938, in Chicago, illinois. he began acting in high school and moved to new york in 1957, where he made his screen debut as a teenage arsonist in a 1957 pilot for a never screened TV series, Chicago 212.

After a variety of film, theatre and TV roles, Thinnes’s big break came with a two- year stint on General hospital, starting in 1963.

Female viewers noticed his piercing blue eyes and rugged good looks — the thricebrok­en nose courtesy of his days as a teenage street brawler.

success in General hospital and a role as Ben Quick in the TV adaptation of William Faulkner’s The Long hot summer saw Thinnes snapped up by producer Quinn Martin to play David Vincent in Larry Cohen’s The invaders.

he married his co-star Lynn Loring, who also acted with him in the movie Journey To The Far side of The sun (1969). They parted in 1984.

Though Thinnes has occasional­ly appeared in films, such as The hindenburg (1975), Airport 1975 (1974) and Blue Bayou (1990), he has remained essentiall­y a TV star. Among his post-invaders TV roles was Dr James Whitman on The Psychiatri­st (1970), Captain (later Major) holms on From here To eternity (1980) and nick hogan on Falcon Crest (1981).

his most notable recent appearance was as the enigmatic alien Jeremiah smith in The X-Files.

Thinnes lives on the West Coast of the states with his fourth wife, French author stephanie Batallier, and concentrat­es on his art work with gallery exhibition­s in Texas and California.

QUESTION Following Blue Planet II’s revelation­s about the sea toad — it’s a fish with feet — what traits do humans share with fish?

ChARLes DARWin once said he thought the evidence from the comparativ­e anatomy of embryos was ‘ by far the strongest single class of facts in favour of change of form’. While it has since been eclipsed by genetics, it remains a compelling argument for evolution.

in this context, perhaps the single most striking details in the comparativ­e embryology of vertebrate­s are structures colloquial­ly known as gill slits.

embryonic gill slits or branchial clefts ( branchia is Greek for gill), or more properly pharyngeal clefts (grooves and folds), are part of what is called the pharyngeal apparatus found in the front (ventral) and sides (lateral) of the head/ neck region of all vertebrate­s in the pharyngula stage of developmen­t.

At this stage, the embryos of all vertebrate­s are similar, having developed the beginning of a spinal cord.

in fish and the larva of amphibians these gill slits develop into respirator­y organs used to extract oxygen from water. in amniotes ( reptiles, birds and mammals) they are modified into the ear drum and glands such as the thymus and parathyroi­d.

Two unwanted vestiges of our fishy ancestry are the propensity of men to suffer from hernia and hiccups.

The gonads of sharks, other fish and humans develop in the same place — the chest. This works well for sharks, as they stay there, but in human males, the gonads need to travel all the way down into the scrotum to keep cool. This causes a looping of the spermatic cord, which causes a weakness in the body wall, leaving them prone to hernia.

The path of the human phrenic nerves begins at the base of the skull and goes through the body cavity to the diaphragm. This is an efficient path to fish and amphibian gills, which are in the neck, but is an inefficien­t path to the diaphragm in humans. The irritation of these nerves can cause problems such as hiccups, a reflexive vestige.

other powerful evidence that fish and humans share ancestry is more obscure. The mammalian left recurrent laryngeal nerve, a branch of the vagus nerve (cranial nerve X) that supplies all the intrinsic muscles of the larynx, appears to have been poorly designed.

it travels downward past the larynx, then round the aorta and back up to the larynx. A much shorter route directly to the larynx would be far more effective.

The evolutiona­ry model, however, is a precise fit, especially when one considers fish anatomy.

in fish, several branches extend from the vagus nerve, each looping around arterial arches that connect the dorsal and ventral aorta between each gill slit, which is a direct route.

QUESTION When and why was it decided there should be 12 members on a jury?

The previous answer reminded me of the following story.

A prolific serial burglar came before the magistrate and was told the case could tried immediatel­y. however, if he wished to plead not guilty, he would go to the Crown Court and his guilt or innocence would be decided by 12 of his peers.

‘excuse my ignorance, but who might these peers be?’ he asked.

‘Twelve people, chosen at random and from the same social background as yourself,’ replied the magistrate.

‘Good grief,’ said the accused. ‘There is no way i want my fate decided by a bunch of thieves!’

More seriously, contempora­ry medieval commentato­rs suggested that juries of the time were not particular­ly impartial. They were usually recruited from groups with a higher social standing than the local peasantry, maybe freemen, craftsmen or village chiefs.

They would almost certainly know the accuser or defendant, and depending on who gave them a brown envelope would give judgment in that direction.
