Edouard Suess attributes to Oswald Heer and HF the generalisation "That the time during which a new species is formed, is (as a rule) very short in comparison with the time during which it persistently presents the same peculiar specific characters". [Edouard Suess, "Über die Verschiedenheit und die Aufeinanderfolge der tertiären Landfaunen in der Niederung von Wien", Sitzungsberichte der Kaiserlichen Akademie der Wissenschaften in Wien (Math-naturw. Klasse) 47 (1863): 306–31.] [See 4277.]
