Green lizards were observed in the region in the image. changes in the geography of the region caused the formation of a stream, which divided the region into two halves. the left half developed a dark green environment, and the right half a comparatively lighter green environment. as a result, two geographically isolated populations, dark and light green lizards inhabited either side of the stream. a stream running between two grassy regions the region on the right has more light green lizards as a result of . the new species will develop by way of .

The correct answers are postzygotic isolation and allopatric isolation.

Explanation:

A kind of reproductive isolation that inhibits species from mating with each other as a consequence of the variations, which has created between them when they are distinguished by physical boundary is known as postzygotic isolation.  

The mode of speciation, which take place when a biological population of similar species becomes separated from each other to an extent that it interferes with genetic exchange is known as allopatric speciation. It generally takes place as a consequence of variation in the environment.
