Minimal autocatalytic networks
Mike Steel, Wim Hordijk, Joshua Smith
Self-sustaining autocatalytic chemical networks represent a necessary, though not sufficient condition for the emergence of early living systems. These networks have been formalise…
Identifying a species tree subject to random lateral gene transfer
Mike Steel, Simone Linz, Daniel H. Huson +1
A major problem for inferring species trees from gene trees is that evolutionary processes can sometimes favour gene tree topologies that conflict with an underlying species tree.…
A formal model of autocatalytic sets emerging in an RNA replicator system
Wim Hordijk, Mike Steel
Background: The idea that autocatalytic sets played an important role in the origin of life is not new. However, the likelihood of autocatalytic sets emerging spontaneously has lon…
Reconstructing fully-resolved trees from triplet cover distances
Katharina T. Huber, Mike Steel
It is a classical result that any finite tree with positively weighted edges, and without vertices of degree 2, is uniquely determined by the weighted path distance between each pa…
Is the Random Tree Puzzle process the same as the Yule-Harding process?
Sha Zhu, Mike Steel
It has been suggested that a Random Tree Puzzle (RTP) process leads to a Yule-Harding (YH) distribution, when the number of taxa becomes large. In this study, we formalize this con…
The impact and interplay of long and short branches on phylogenetic information content
Iain Martyn, Mike Steel
In molecular systematics, evolutionary trees are reconstructed from sequences at the tips under simple models of site substitution. A central question is how much sequence data is…
Autocatalytic Sets Extended: Dynamics, Inhibition, and a Generalization
Wim Hordijk, Mike Steel
Background: Autocatalytic sets are often considered a necessary (but not sufficient) condition for the origin and early evolution of life. Although the idea of autocatalytic sets w…
The Structure of Autocatalytic Sets: Evolvability, Enablement, and Emergence
Wim Hordijk, Mike Steel, Stuart Kauffman
This paper presents new results from a detailed study of the structure of autocatalytic sets. We show how autocatalytic sets can be decomposed into smaller autocatalytic subsets, a…
Root location in random trees: A polarity property of all sampling consistent phylogenetic models except one
Mike Steel
Neutral macroevolutionary models, such as the Yule model, give rise to a probability distribution on the set of discrete rooted binary trees over a given leaf set. Such models can…
On Patchworks and Hierarchies
Andreas Dress, Vincent Moulton, Mike Steel +1
Motivated by questions in biological classification, we discuss some elementary combinatorial and computational properties of certain set systems that generalize hierarchies, namel…
