A scientist studying a species of duck (species A) finds that this species only occurs in one small lake. Despite similar lakes
that occur several hundred miles to the north, the other lakes are inhabited by a similar, but different duck species (species B). Which statement could be true?
There are some species of animals and plants in the earth that are developed in one specific place due to the different conditions that can affect the development in life of an alive being such as temperature, pressure, altitude, humidity, water conditions, and a lot of other geographical conditions that have an influence in life. That is why some species are endemic from a particular place that can be a continent or also a small lake.
