Would the following organisms be considered separate species according to the biological species concept? Answer "True" for yes (separate species), and "False" for no (the same species). 1. Lions and tigers can interbreed to produce viable, fertile offspring, but lions live in open grasslands and tigers live in dense forests.
Hybrid offspring have low fitness relative to the parental species. Indicate whether each scenario would promote or prevent speciation in humans. Nuclear warfare destroys 99% of the human population, leaving only small pockets of survivors. A small population of humans establishes a colony on Mars and no more spaceships arrive.
Over many generations, the flycatchers diverge between the two islands and become reproductively isolated. Which of the following likely contributed to this divergence? Determine whether the examples are most likely to undergo allopatric or sympatric speciation.
