Primate Anatomy Understanding Evolution Evolution is NOT a goal oriented process a primate is not “superior” to another- each is uniquely adapted to their habitat This helps answer the question: “ If people evolved from apes, why do apes still exist?” Terms to know Morphology 1. The form of an anatomical structure (shape,size) “Primitive” traits 1. Traits or a combination of traits present in an ancestral form “Specialized” or derived traits 1. Evovled for a particular function 2. Not present in the ancestor Primates are distinguished from other mammals by their specialized morphology and traits. .. General Primate Traits 1.

Reduced reliance on senses of smell and hearing • 1.Versatile skeletal structure 1. Erect posture 2. Flexible and general limb structure 3. Divergent Thumb (pollex) 4. Divergent (opposable) big toe (hallux) 5. Pentadactility (five digits) and nails, not claws, contribute to whole hand prehensility (grasping ability) • 2. Enhanced Sense of Touch 1. Tactile pads enhance our sense of touch 2. Fingerprints at the tips (dermatoglyphics) enhance grip 3. Hands rather than snout, used as an exploratory and manipulative organ • 3....
