Reticulate evolution can happen between lineages separated only for a short time, for example through hybrid speciation in a species complex. Nevertheless, it also takes place over larger evolutionary distances, as exemplified by the presence of organelles of bacterial origin in eukaryotic cells.
Phylogenetic trees also have trouble depicting microevolutionary events, for example the geographical distribution of muskrat or fish populations of a given species among river networks, because there is no species boundary to prevent gene flow between populations. Therefore, a more general phylogenetic network better depicts these situations.

Two forms of reticulation can be distinguished: Terminal reticulation and inner reticulation. In a terminal reticulation a single taxon or next-level-key is keyed out in several locations in the key. This type of reticulation is normally compatible with any printable presentation format of identification keys and normally does not require ...
Reticulation is a net-like pattern, arrangement, or structure. Reticulation or Reticulated may refer to: Reticulation (single-access key), a structure of an identification tree, where there are several possible routes to a correct identification; A coloration pattern of some animals (e.g. the reticulated giraffe)
These include comparison of model predictions with repeated data. An attempt to predict the residuals m(, ) with the operating conditions c using linear regression will show if the residuals can be predicted. [21] [22] Residuals that cannot be predicted offer little prospect of improving the model using the current operating conditions. [5]
black box model: No prior model is available. Most system identification algorithms are of this type. Most system identification algorithms are of this type. In the context of nonlinear system identification Jin et al. [ 9 ] describe grey-box modeling by assuming a model structure a priori and then estimating the model parameters.
The original model assumes that if an allele has a mutation that causes it to change in state, mutations that occur in repetitive regions of the genome will increase or decrease by a single repeat unit at a fixed rate (i.e. by the addition or subtraction of one repeat unit per generation) and these changes in allele states are expressed by an integer (. . .
