Answer:
Sympatric speciation.
Explanation:
Sympatric speciation occurs between Crematogaster ashmeadi and Linepithema humile ants because they live on the same geographical location. Sympatric speciation is a type of speciation in which ancestral population evolve into separate species without separation of geography. Hybrid sterility is the postzygotic isolating mechanism that decreases the fitness of the hybrid individuals and helps in controlling the population of an organisms..
Answer:
I would write "terrestrial/lives on land during all life stages" between the frog and pigeon branches.
Explanation:
Jaw evolution has started with fish, so i'd place that before the perch, evolution of four limbs is next and I would plate it between the perch and the frog. Evolution of an egg has ensured that organisms remain terrestrial during all stages of life and don't need to rely on water to lay their eggs. So I would place that between the frog and the pigeon. True mammary glands and true hair, as we know it formed on mammals so i'd place that between the pigeon and the rats (although synapsids evolved similar structures long before birds even existed). And lastly, I would place "walking on two legs" between rats and human branches. Because our ancestors evolved bipedalism relatively late.
