Another remarkable example of a similar concrete construction are the two airplane hangars for the Italian Air Force in Orvieto, Italy, by Italian architect and structural engineer Pier Luigi Nervi, designed in 1935 and built in 1938. They were also destroyed during World War II.

The molecular clock (based on the molecular clock hypothesis (MCH)) is a technique in genetics, which researchers use to date when two species diverged.It deduces elapsed time from the number of minor differences between their DNA sequences. It is sometimes called a gene clock.The notion of a molecular clock was first attributed to Emile Zuckerkandl and Linus Pauling who, in 1962, noticed that the quantity of amino acid differences in hemoglobin between lineages roughly matched the known evolutionary rate of divergence based upon fossil evidence.t is sometimes called a gene clock.
