- Fragmentation of forests leads to allopatric speciation: Deforestation fragments habitats. Allopatric speciation occurs when populations are geographically isolated, so this is correct.
- Animal species evolve differently to suit the environment: Different fragmented habitats exert new selection pressures, driving divergent evolution, so this is correct.
- Animal species migrate to different ecosystems: Deforestation destroys habitats, forcing animals to move to find suitable environments, so this is correct.
- Animal species have a decreased chance of speciation: Deforestation and fragmentation actually increase the chance of allopatric speciation (geographic isolation), so this is incorrect.
- Animal species will have an increased chance of finding an unrelated mate: Deforestation reduces population sizes and fragments them, decreasing mate availability (especially related mates? No, actually, it reduces overall mate access and can increase inbreeding, so this is incorrect.
