How is the molecular clock concept used to construct phylogenies?
How is the molecular clock concept used to construct phylogenies?
- By identifying the most recently evolved species in a lineage
- By comparing the DNA sequences of unrelated species
- By calculating the time elapsed since species diverged from a common ancestor using known mutation rates (correct)
- By measuring the rate of evolution within a single generation

- Step 2 - Highest fitness individuals contribute the most to the next generation (correct)
- Step 4 - Only the best few solutions are selected as parents
- Step 1 - Initialization of the population with random solutions
