A comparative analysis of L1 retrotransposition activities in human genomes suggests an ongoing increase in L1 number despite an evolutionary trend towards lower activity

Table 1 Parameters of the speciation-extinction model fitted to L1 phylogenetic tree with binary retrotransposition activity data

Parameter	Description
λ₀	Speciation rate of low activity L1
λ₁	Speciation rate of high activity L1
μ₀	Extinction rate of low activity L1
μ₁	Extinction rate of high activity L1
q₀₁	Rate at which low activity L1 change into high activity L1
q₁₀	Rate at which high activity L1 change into low activity L1
