Describe one difference between the humerus of the whale and the humerus of the human.
Answer
One difference between the humerus of the whale and the humerus of the human is that the whale's humerus is more streamlined and adapted for swimming, while the human's humerus is structured for a wider range of bipedal movement and manipulation.
Step 4
Describe one difference between the phalanges of the horse and the phalanges of the human.
Answer
One difference between the phalanges of the horse and the phalanges of the human is that the horse has fewer phalanges; it typically has three phalanges in each leg, while a human has fourteen phalanges in their fingers and toes.
Step 5
Describe how the thinner beak of species A is a result of evolution.
Answer
The thinner beak of species A is a result of evolution due to variations in beak shape that occurred over generations. Thinner beaks are better suited for extracting food, leading to increased success in obtaining food from their environment. Birds with thinner beaks were more likely to survive and reproduce, passing this trait on to their offspring. Over many generations, this trait became more common due to natural selection.
