Rather, the shared coevolutionary history of the anthropoid primates and their lice contains a mixture of evolutionary events including cospeciation, parasite duplication, parasite extinction, and host switching.
This is expected as real data is more likely to fall along a continuum caused by a mixture of evolutionary processes, rather than fit yes/no definitions for the adaptive radiation metaphor [ 71].
During this period Lansbury published his political credo, My England (1934), which envisioned a future socialist state achieved by a mixture of revolutionary and evolutionary methods.
Whole gene contents of any genome can be the result of a mixture of different evolutionary events such as vertical inheritance of genes and their duplication, gain and loss events, and their relative contributions may vary among different species [ 46].
Thus, the use of synonymous codons in any gene can be the result of a mixture of these different evolutionary factors, and their relative contributions may vary among different species depending on their life history.
For constrained states, since we do not know the exact form of constraint at each position, we opted to use a mixture model and assume that the conditional probability P(S i | z i =1) is described by a mixture of K constrained evolutionary models: (14) where π k represents the constraint vector associated with model k, and P(k) is its prior distribution.
Or, as Konrad Ott puts it: "If you are unlucky, you will catch an adherent of Singer, Tooley or colleagues when you are a disabled infant, or as an asylum seeker, somebody who defends a mixture of 'hard' communitarianism and evolutionary ethics" ([ 26], p. 73; own translation).
Thus, the data one obtains represent the mutations in a mixture of cells with potentially distinct evolutionary histories.
The radiation of phyllostomid bats is actually a number of radiation episodes nested within each other, caused by a mixture of adaptive and non-adaptive evolutionary mechanisms.
The stable model is well suited to a stochastic process with a volatile rate of change in which biological characters undergo a mixture of neutral drift and occasional evolutionary events of large magnitude.
In this hypothesis, mosaic evolution, where some exons evolve divergently and others evolve concertedly, would explain the mixture of evolutionary patterns seen in the phylogenetic trees.
