Patterns of evolution, as illustrated by the fossil record
As one example, so-called heterodont dentition has apparently evolved
polyphyletically. Similarly, crossed-lamellar shell structure has evolved
polyphyletically from the primitive prismato-nacreous condition (Taylor, 1973). In

Classification and Biology
... serious phylogenist would deny that particular characters may at times arise
polyphyletically. Many botanists and zoologists argue that any character which
possesses an evident adaptive value is a priori likely to have arisen
polyphyletically; ...

The Chloroplast: From Molecular Biology to Biotechnology: ...
Different from primary eukaryotes, these plants arose polyphyletically and hence
evolved independently of each other, with both different hosts and different
engulfed microalgae [3-5]. This is in line with the occurrence of different antenna

Plants and the Human Brain
In contrast, the synthesis of tropane alkaloids developed polyphyletically
following independent genetic events in a number of families of plants.
Polyamines, such as putrescine, spermine, and spermidine, are primary
metabolites synthesized ...

Biology of Coelenterata
Evolutionary studies of trends within Family Lithostrotionidae have shown that the
parallels are so close in several descendent stocks that species originally
lumped in the same genera were actually derived polyphyletically.

Termites: Evolution, Sociality, Symbioses, Ecology
According to Noirot and Pasteels [99], workers arose polyphyletically during the
evolution of termites: once in the Hodotermitidae, at least once in the
Rhinotermitidae plus Termitidae clade, and once in the Mastotermitidae.

Genetics and Evolution of Aquatic Organisms
The situation in this genus is similar to that of Lasaea in that clones have arisen
polyphyletically through multiple hybridizations between diploid parental species.
Echelle and colleagues recommend that the clonal complex, formerly treated as ...
