What are dolphins, horses, and modern humans adapted for?

1.Dolphins:
– Dolphin skull including: 1. The “telescoped” cranial and facial bones and features 2. Aquatic breathing and sound generating system (nasal opening blowhole) , lungs, air passages, phonic lips, melon, etc.) 3.Food acquisition and processing system (jaws, jaw muscles, dentition ) 4. Aquatic hearing (echolocation, communication) system (from acoustic window to fat pad in hollow mandible to auditory bullae with an involucrum up autic nerve to large and complex brain for echo interpretation.)

-Aquatic locomotor (swimming) system (torpedo shaped body, front limb (flipper for steering), Hind limb (vestigial, Spine (flexibility, musculature) tail (flukes), etc. )

2. Horses: investigate and illuminate (draw/ diagram /print, label, and describe) the historical development and adaptive significance of each of the following anatomical systems present in modern HORSES.

– Pelage (Hair/fur: vibrissae, insulation, protection, protective coloration,
– olfactory system (nostrils, turbinal bones, jacobson’s organ, olfactory bulb of brain, etc.)
– tactile system (vibrissae, lips tongue, etc.)
-Auditory System (Pinnae, ear tube, ear drum, ear ossicles, inner ear (especially the cochlea)
– visual system (eyes: pupil, lense retina, teptum lucidum, etc. Also: orbit placement, visual field, etc.)
– masticatory system (lips, tongue, jaws, jaw muscles, dentition (incisors, canines, premolars, molars) etc.)
-Unguligrade locomotor system (pectoral girdle- front limb, pelvic girdle, hind limb, lumbar vertebrae,etc.)

3. MODERN HUMANS: : investigate and illuminate (draw/ diagram /print, label, and describe) the historical development and adaptive significance of each of the following anatomical systems present in modern humans ( homo sapiens)

– Hearing system (pinnae, ear tube, ear drum, ear ossicles, cochlea, auditory regions of brain, speech centers including broca’s (speaking, wrting, tool making ) and wernicke’s areas( understanding language ) etc. )

– Visual system (eyes: pupil, lense retina, rod and cone cells, retinal fovea for trichromatic color and precision vision) ALSO: boney orbital capsules, overlapping visual fields for depth perception,etc.
– Masticatory system (jaws, Jaw muscles dentition including incisors, canines, pre-molars, molars, plus lips, cheeks, tongue, etc.)
– Arm and hand adaptations (shoulder, arm, wrist, palm and finger bones, five digits, long opposable thumb, short fingers, nails backing tactile pad with dermatoglyphs, fine motor and power gripping manipulation capability, etc.)
– Bipedal locomotor system (adaptations of the spine, pelvis, leg and foot: adaptations for walking striding, jogging, sprinting, jumping, kicking, climbing, etc .)
– Skin (organ system) : protection, body hair, tactitle capabilities, pigmentation, thermoregulation, eccrine ( sweat) glands, subsurface capillaries, subcutaneous fat for energy storage, insulation, etc.)
