Question

based on the anatomical features of the embryos, which pairs of organisms are likely most closely related? choose two (2) answers. fish and tortoise pig and human chicken and pig tortoise and chicken

Explanation:

• Pig and Human: Both are mammals, so their embryos have similar anatomical features due to shared evolutionary history.
• Tortoise and Chicken: Tortoises (reptiles) and chickens (birds) are both amniotes, and their embryos show related anatomical traits from a common amniotic ancestor.
• Fish (aquatic, non - amniote) and Tortoise (amniote, reptile) have more distant evolutionary relationships. Chicken (bird) and Pig (mammal) also have relatively less similar embryonic anatomy compared to the other two pairs.

Answer:

B. Pig and Human
D. Tortoise and Chicken
