Molecular Clock

MOLECULAR CLOCK

Mutation rate (μ): 0.001/site/gen Sequence length: 100 bp Fossil calibration: 500 Mya Time speed: 5 gen/frame Lineages: 2

Time elapsed: 0 gen

Div 1-2: 0 subs/site

Estimated time: — gen

Clock error: —%

Calibrated age: — Mya

Molecular clock: neutral mutations accumulate at rate μ. Sequence divergence = 2μt. Fossil calibration converts substitutions/site → absolute time.
