Bird guides once listed the myrtle warbler and Audubon's warbler as distinct species Recently, these birds have been reclassifie
d as eastern and western forms of a single species, the yellow-rumped warbler. Which of the following pieces of evidence, if true, would be cause for this reclassification? The two forms live in similar habitats and have similar food requirements The two forms have many genes in common. The two forms interbreed often in nature, and their offspring survive and reproduce well.
The two forms interbreed and their offspring survive and reproduce well.
Explanation:
When talking about classification of species, one of the first features observed is the species fitness, which describes the reproductive success or their ability to leave to their successive generations the most copies of their genotype. When different species that were recently divided into 2, by geographic isolation, for instance, usually there is no genetic compatibility, and if its possible to produce offspring, there might be some development issues like infertility.
