sentences: the opposite of the same is different & two birds are not in the same taxonomic family ->  two birds are in different taxonomic families  two birds live in environments with similar characteristics & environments with similar characteristics place similar environmental pressures on the organisms in them ->  two birds developed under similar environmental pressures  if two things are thousands of miles apart then those two things are separate from each other & two birds developed thousands of miles apart ->  two birds developed separate from each other  two birds developed under similar environmental pressures & two birds developed separate from each other ->  two birds developed in separate environments under similar environmental pressures  two birds are in different taxonomic families & two birds developed in separate environments under similar environmental pressures ->  two birds from different taxonomic families developed in separate environments under similar environmental pressures  a bird is a kind of organism & a species is a group of a certain kind of organism ->  a species can be a group of a certain kind of bird  a species can be a group of a certain kind of bird & convergent evolution is when two species in different taxonomic families develop in different places under similar environmental pressures ->  convergent evolution can be when two kinds of birds in different taxonomic families develop in different places under similar environmental pressures  two birds from different taxonomic families developed in separate environments under similar environmental pressures & convergent evolution can be when two kinds of birds in different taxonomic families develop in different places under similar environmental pressures -> an example of convergent evolution is two birds from different taxonomic families developing in separate environments under similar environmental pressures
