The origin of the animals and a 'Savannah'hypothesis for early bilaterian evolution
The earliest evolution of the animals remains a taxing biological problem, as all extant
clades are highly derived and the fossil record is not usually considered to be helpful. The …

Frameworks for interpreting the early fossil record of eukaryotes
The origin of modern eukaryotes is one of the key transitions in life's history, and also one of
the least understood. Although the fossil record provides the most direct view of this process …

Fundamental constraints to the logic of living systems
It has been argued that the historical nature of evolution makes it a highly path-dependent
process. Under this view, the outcome of evolutionary dynamics could have resulted in …
