Carl H. Eigenmann an ichthyologist wrote Cave vertebrates of America: a study in degenerative evolution (1909) in which he concluded that cave evolution was essentially degenerative. The entomologist William Morton Wheeler and the Lamarckian Ernest MacBride (1866-1940) also advocated degenerative evolution.

Maleic acid or cis-butenedioic acid is an organic compound that is a dicarboxylic acid, a molecule with two carboxyl groups. Its chemical formula is HO 2 CCHCHCO 2 H. Maleic acid is the cis-isomer of butenedioic acid, whereas fumaric acid is the trans-isomer.It is mainly used as a precursor to fumaric acid, and relative to its parent maleic anhydride, maleic acid has few applications.aleic acid is an industrial raw material for the production of glyoxylic acid by ozonolysis. Maleic acid may be used to form acid addition salts with drugs to make them more stable, such as indacaterol maleate.
