Cricket's finicky mating behavior boosts biodiversity
...s Mendelson, "lineages - species that have split - cease to recognize each other as mates. Although the ancestors recognized each other as mates, the descendants no longer do because of evolutionary change. In the case of Laupala, members of the two species are physiologically capable of mating. But they a......ed receptors become engulfed by the cell, and thus cease signaling. In response, the cell halts growth and, when chemotherapy is used in combination with the immunotherapy, it dies.
