A brood parasitic bird, the common cuckoo, is divided into host races, each characterized by egg mimicry of different host species.
WebDec 1, 1999 · The initial step of Bush’s sympatric speciation model for Rhagoletis and other phytophagous and parasitic animals (Diehl & Bush, 1989; Bush, 1994) is the evolution of a host race (a partially ... WebSpeciation is thereby envisaged as having two phases: (i) the evolution of host races from within polymorphic, panmictic populations; and (ii) further reduction of gene flow between host races until the diverging populations can become generally accepted as species. We apply this criterion to 21 putative host race systems.
WebDec 4, 2012 · Several other genera of Tephritidae are known to have undergone race formation and speciation through host association (Bush 1969; Abrahamson and Weis 1997), so the uniquely broad host range of S. longipennis is an indication that it could be a conglomerate of cryptic lineages. WebHost–parasite coevolution is a special case of coevolution, where a host and a parasite continually adapt to each other. This can create an evolutionary arms race between them. ... potentially enhancing biodiversity and possibly speciation. Host–parasite coevolution may also affect the underlying genetics, for example by favouring increased ...
WebSpeciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge. In allopatric speciation, groups from an ancestral population evolve into separate species due to a period of geographical separation. In …
