Having an Insight into Malware Phylogeny: Building Persistent Phylogeny Tree of Families

Evaluation of Malware Phylogeny Modelling Systems Using Automat

A malware phylogeny model is an estimation of the derivation relationships between a set of species of malware. Systems that construct phylogeny models are expected to be useful for malware analysts. While several different phylogeny construction systems have been proposed, little is known about effective ways of evaluating and comparing them. Little is also known about the consistency of their...

The binary perfect phylogeny with persistent characters

The binary perfect phylogeny model is too restrictive to model biological events such as back mutations. In this paper we consider a natural generalization of the model that allows a special type of back mutation. We investigate the problem of reconstructing a near perfect phylogeny over a binary set of characters where characters are persistent: characters can be gained and lost at most once. ...

Phylogeny and the Tree of Life

 Phylogeny is the evolutionary history of a species or group of species.  To reconstruct phylogeny, scientists use systematics, an analytical approach to classifying the diversity and determining the evolutionary relationships of living and extinct organisms. o Evidence used to reconstruct phylogenies can be obtained from the fossil record and from morphological, biochemical, and genetic simi...

Phylogeny and the Tree of Life

Phylogeny reconciliation under gene tree parsimony

The growing genomic and phylogenetic data sets represent a unique opportunity to analytically and computationally study the relationship among diversifying species. Unfortunately, such data often result in contradictory gene phylogenies due to common yet unobserved evolutionary events, e.g., gene duplication or deep coalescence. Gene tree parsimony (GTP) methods address such issue by reconcilin...
