Hearing apparatus
Mammals
Ears only in their head
Only one common principle
Of ear design
Cochlea
Constrained
Same biophysical principles
Respective molecular processes
For mechanotransduction
Share a common evolutionary origin
Earliest life
3.7 billion years ago
Two billion years later
Eukaryotes evolved
From an endosymbiotic amalgamation of prokaryotic
components
Flagella/cilia
Difference that evolved in eukaryotes
Microtubule cytoskeleton
Linear repeating chain
Tubulin proteins
In oxygen-poor primordial broth
Hot
Simple single-celled prokaryotic organisms
Tapestry of membrane-bound receptor proteins
Interactions with their environment
Insects
Evolved at least 19 times
In different insect groups
Can be found in completely different body parts.
Morphologies and functional characteristics
Wildly diverse
Constrained
