You are looking at cat eyes and human eyes. List 2 similarities and 2 differences between the two and explain why you think these adaptions occurred.
**Quality of your points are up to Ms. Turner's discretion**
SAME: Simple/camera eyes, can see colour like humans (similar amount of cones), similar anatomy (e.g., lens, cornea, retina, etc...).
DIFFERENT: Tapetum lucidum, non-round pupil, no white part of eye, more rods.
