Sentence examples for species challenges from inspiring English sources

At the microevolutionary level, the likely existence of a billion prokaryotic species challenges microbiologists to determine what might promote rapid speciation in prokaryotes, and to identify the ecological dimensions upon which new species diverge and by which they may coexist.

However, the high degree of sequence conservation between prodomains amongst different species challenges this dogma and strongly suggests additional biological functions [9].

The bacterial species challenge: making sense of genetic and ecological diversity.

New hantaviruses have been discovered in shrews, moles and bats and increasing evidence points at host-switching events and co-circulation in multiple, sympatric reservoir species, challenging the strict rodent virus co-evolution theory.
