1. How do the various characteristics of animal skulls indicate the importance of one sense over another? 2. What skull features do prey animals have in common? 3. What skull features do predator animals have in common? 4. What can be learned by studying the dentition of various mammal skulls? 5. How do carnivore and primate skulls differ? 6. Describe the characteristics of each of the animal skulls that you classified. This comes from: http://www.mhhe.com/biosci/genbio/virtual_labs/BL_27/BL_27.htmExplanation / Answer
Ans:
1)how it works is that if a Nasal cavity(nose) is larger it indicates that there was more room there for tissue that would be used for that particular action (smelling)
2)Their eyes are in the front of their head to help them judge distance very well.
The relative size of the nasal passage in a skull is an indication of the animal’s sense of smell.
3)
Long, strong jaw bones (a long-ish snout shape or strong beak) with sharp teeth/beaks to crush bones and tear flesh off.
4)
The dentition of various animals corresponds to their lifestyles and environmental adaptations. For example, carnivores have sharp, pointed incisors and canines that are designed to tear apart flesh and muscle, they also have short alimentary (digestive) tracts, because meat doesn't take long to break down. Herbivores have broad teeth to chew through plant, and long digestive systems to fully break down plant cell walls. By studying dentition, one could learn how an animal ate and lived. This would lead to understanding how the animal acted in its environment (predatory or prey), and who knows what else. Much can be learned from it, suffice it to say.
5)
The pointiness of the teeth. Primates have teeth for cutting and chewing. Carnivores have teeth for catching, biting into, and holding prey. Primates do the catching and holding prey with hands.
Also, the positioning of the ears. Primates have side-facing ears. Most carnivora have the ears positioned more forward-facing.
Last, the lower jaw is more restricted in motion in carnivora. Primates have some side-to-side movement, for grinding of food when chewing. Carnivora move the lower jaw only up-down.
