Two groups of birds, A and B, have not been observed to mate in nature, and hybrids produced by laboratory matings are unable to reproduce. Birds in the two groups have similar color patterns, the same beak shape and beak size, and the same average wing span. Based on analyses of gene (DNA) sequences, group A appears to be most closely related to a species of sparrow, while group B is more closely related to a species of finch. Based on this information, under which species concept(s) would group A and group B be considered different species?

Species Concept

Explanation:

Based on the given information, group A and group B can be considered different species under biological species concept  and phylogenetic species concept

Because the two groups of birds share similar physical characteristics, they would not be considered different species under the morphological species concept The two groups have not been observed to mate, and hybrid offspring generated in a lab cannot reproduce, both of these observations support the hypothesis that they are different species under the biological species conceptThe fact that group A is more closely related to sparrows, while group B is more closely related to finches supports the hypothesis that they are different species under the phylogenetic species concept

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
