A Tale of Unequal Substitution

Digital Necrosis: A Hoarder’s Tale

The probability of speciation on an interaction network with unequal substitution rates.

Speciation is characterized by the development of reproductive isolating barriers between diverging groups. A seminal paper of a mathematical model of speciation was published by Orr (1995), extended by Livingstone et al. (2012) to incorporate interaction networks. Here, we further develop the model to take into account the possibility of different substitution rates for network nodes of differ...
