Can computer simulations help to unravel the evolution

of circadian clocks?

React vs. Anticipate

@DerSchmelling

Circadian clocks are ubiquitous

@DerSchmelling

Circadian clocks provide fitness advantage

@DerSchmelling

→ Anticipate is better than react

● Competition experiment with WT and clock mutant

● No effect in constant light● WT has fitness advantage in

oscillating condition

Digital Organisms

@DerSchmelling

Digital organisms are unlimited data sources

@DerSchmelling

Problem Solution● Evolution

happens extremely slowly

● Data collection is hard

Computer simulationwith

digital organisms

Three criteriafor evolution● Replication● Variation

(Mutation)● Competition

Don’t feel the pressure to do everything at once. Even one step towards open science is great.
