Why is Homologous traits wrong? N o, humans have never been born with gills. This is almost certainly because humans and fish share some DNA and a common ancestor, not because we go though a fish stage when in our mothers' wombs as part of our development towards biological perfection. Similarity not due to common ancestry is called _______. No, the human fetus never develops gills, tail or a yolk sac, as some have claimed. For each of the following, provide an explanation of how the forelimb has evolved. So over the next few weeks, they begin to practice their breathing by carrying out small swallowing movements while expanding and contracting their lungs. Given the continued oozing of blood at the suture sites, both slits were closed with suture for hemostasis the next day without reaccumulation of the subcutaneous air (Figure 5).Although the patient's pulmonary status improved in the days after his cardiac arrest and he recovered brainstem reflexes and could locate the source of a stimulus, the patient subsequently developed fungal septicemia .
