Inheritance of Fertility—Facts, Opinions, and Speculations

Bacteria are different: observations, interpretations, speculations, and opinions about the mechanisms of adaptive evolution in prokaryotes.

To some extent, the genetic theory of adaptive evolution in bacteria is a simple extension of that developed for sexually reproducing eukaryotes. In other, fundamental ways, the process of adaptive evolution in bacteria is quantitatively and qualitatively different from that of organisms for which recombination is an integral part of the reproduction process. In this speculative and opinionated...

Telegony, the sire effect and non-mendelian inheritance mediated by spermatozoa: a historical overview and modern mechanistic speculations.

Telegony is the belief that the sire first mated to a female will have an influence upon some of that female's later offspring by another male. Although the reality of telegony was acknowledged by such authorities as Darwin, Spencer, Romanes and many experienced breeders, it has been met with scepticism because of Weismann's unfavourable comments and negative results obtained in several test ex...

Speculations on Story Puns

There is a class of joke which consists of an anecdote , which is sometimes quite long and often has no inherently humorous content, followed by a punchline which is a distorted form of some well-known phrase, proverb or quotation. Usually the punchline purports to summarise or draw a moral from the preceding story. This genre has some unusual aspects, from the viewpoint of conventional claims ...

Speculations on Hodge theory

Recall that a Mumford–Tate domain DM is an open set in its compact dual ĎM — the latter is a rational homogeneous variety defined over Q (think of the upper half plane H ⊂ P1). Thus a polarized Hodge structure (PHS) φ has an “upstairs” field of definition k(φ). If H•,• ⊂ T •,• is a subalgebra then the Noether-Lefschetz locus NLH = {φ : Hg•,• φ ⊇ H} is defined over Q. Its components are defined ...
