To introduce selection into a model of coalescence, I explore the use of modified integer partitions that allow the identification of a preferred lineage. I show that a partition-partition transition matrix, along with Monte Carlo discrete time kinetics, treats both the neutral case and a wide range of positive and negative selection pressures for small population sizes. Selection pressure causes multiple collisions per generation, short coalescence times, increased lengths of terminal branches… 


Coalescents with Simultaneous Multiple Collisions
We study a family of coalescent processes that undergo ``simultaneous multiple collisions,'' meaning that many clusters of particles can merge into a single cluster at one time, and many such mergers
The general coalescent with asynchronous mergers of ancestral lines
Take a sample of individuals in the fixed-size population model with exchangeable family sizes. Follow the ancestral lines for the sampled individuals backwards in time to observe the ancestral
Genealogies in simple models of evolution
It is discussed how coalescence times which grow logarithmically with the size of the population in contrast with the linear growth of the neutral case are modified in a simple way of introducing selection.

A Classification of Coalescent Processes for Haploid Exchangeable Population Models
We consider a class of haploid population models with nonoverlapping generations and fixed population size N assuming that the family sizes within a generation are exchangeable random variables. A

Dynamics of the evolving Bolthausen-Sznitman coalecent
The limiting behavior of the evolution of the time back to the most recent common ancestor and the total length of the branches in the tree are obtained and a new result concerning the number of blocks in the Bolthausen-Sznitman coalescent is obtained.
Random Recursive Trees and the Bolthausen-Sznitman Coalesent
We describe a representation of the Bolthausen-Sznitman coalescent in terms of the cutting of random recursive trees. Using this representation, we prove results concerning the final collision of the
The solitary wave of asexual evolution
It is shown that the accumulation of advantageous mutations is slowed by linkage over a broad, finite range of population size and supports the view of Fisher and Muller, who argued in the 1930s that progressive evolution of organisms is slowed because loci at which beneficial mutations can occur are often linked together on the same chromosome.
Effect of selection on ancestry: an exactly soluble case and its phenomenological generalization.
A family of models describing the evolution under selection of a population whose dynamics can be related to the propagation of noisy traveling waves, and one striking result is that, for this particular model, the genealogical trees have the same statistics as the trees of replicas in the Parisi mean-field theory of spin glasses.
