Document Summary

Different animals literally see the world differently: uv light unpolarised light, this is what we see as humans, the light is scattered, polarized light this light all goes in the same direction. Animals have adapted to extract accessible information from their environment u pov: uv light, polarized light, vibrations, odours. Whistling moths - ears: ears on thorax allows for improved detection of predators, other moths have ears in the same location for feedback on wing movement. It is metabolically costly to produce, maintain, and process all information from sensory system, you can flood the system and this is why not all information we take in is important. Sensory drive hypothesis - predicts adaptation in sensory and signaling systems to different environments can cause premating isolation between populations: guppies vary in light sensitivity. Low sensitivity group and high sensitivity group: differences were greater after a number of generations, basically showed that sensory systems can drive selection.
