2.
The features that evolved in the human supralaryngeal airway which allowed for speech production include:
3. The position and shape of the Neandertal (_______) bone may indicate that they possessed the ability to speak.
A. limbs evolved after some species had already adapted to living on land B. the first tetrapods evolved from aquatic insects C. limbs evolved in the water, allowing some tetrapods to adapt to life on land D. the first tetrapods had wings, which allowed them to adapt to life outside of water E. none of these answers are correctExplanation / Answer
1)C)
limbs evolved in the water, allowing some tetrapods to adapt to life on land.this is evident from tiktaalik fish , which had characters of fish and tetrapods, it had fins, scales like a fish and rib cage , flat head like tetrapod . The most intriguing fact was it had a little limb with its hip bone ,which suggests they had grown limb like structure while in water which later came to use when they started roaming on earth.
2)D) all the above , also expanding size of cranium, bipedal posture also put an evolutionary pressure to human speech devolopment , though structure of larynx plays a major role.
3) The position and shape of the Neandertal (____hyoid___) bone may indicate that they possessed the ability to speak. This is a horse shoe shaped bone (semicircular) , its presence indicated the ability of speech.
