It seems like your question may have some unclear elements. If you're asking about how a population might be affected when split by a river before speciation is complete, it's crucial to note that geographical barriers can lead to isolation, which may accelerate speciation. If the river dries up, rejoining the populations could result in gene flow and potentially reduce the divergence that had begun. For effective management, it would be important to consider the ecological impacts of the river's condition on both the populations and their habitats.
A population of animals is split in half by a river before spectation is complete the two halves are rejoined when a drought casues the river to run dry how would this impact the two population
