Testing the Hamilton-Zuk Hypothesis: Past, Present, and Future [PDF]
Integrative and Comparative Biology, 2014 Hamilton and Zuk proposed a good-genes model of sexual selection in which genetic variation can be maintained when females prefer ornaments that indicate resistance to parasites. When trait expression depends on a male's resistance, the co-adaptive cycles between host resistance and parasite virulence provide a mechanism in which genetic variation for ...

Mass extinctions past and present: a unifying hypothesis [PDF]
, 2008 Abstract. Enzymes are often referred to as the "agents of life" – a very apt term, since essentially all life processes are controlled by them. Typically, these enzymes only function across a narrow band of environmental conditions, particularly temperature and pH.

State-to-State Cosmology: A New View on the Cosmological Arrow of Time and the Past Hypothesis [PDF]
Foundations of Physics, 2022 Cosmological boundary conditions for particles and fields are often discussed as a Cauchy problem, in which configurations and conjugate momenta are specified on an "initial" time slice. But this is not the only way to specify boundary conditions, and indeed in action-principle formulations we often specify configurations at two times and consider ...

A Toy Model Provably Featuring an Arrow of Time Without Past Hypothesis
The laws of Physics are time-reversible, making no qualitative distinction between the past and the future—yet we can only go towards the future. This apparent contradiction is known as the "arrow of time problem". Its current resolution states that the future is the direction of increasing entropy.

New Difficulties for the Past Hypothesis [PDF]
Philosophy of Science, 2021 I argue that explanations for time asymmetry in terms of a ‘Past Hypothesis’ face serious new difficulties. First I strengthen grounds for existing criticism by outlining three categories of criticism that put into question essential requirements of the proposal.
