The populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring. The populations are isolated and thus do not interbreed. The populations become totally separated from one another. The populations successfully interbreed. 2 points Save Answer QUESTION 4 Which stage is the first stage of speciation? The populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring. The populations are isolated and thus do not interbreed. The populations become totally separated from one another. The populations successfully interbreed. 2 points Saved QUESTION 5 The Colorado River carved out a deep canyon in the habitat of an Abert’s squirrel population. This is an example of which stage of speciation? The populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.
