22. Keynote: Role of epigenetic variation in adaptation

Recent experiments have shown that spontaneous epigenetic variation exists. This means variation in heritable epigenetic changes that behave in a manner analogous to genetic variation. Currently this sort of variation is best understood for DNA methylation in plants. We know that spontaneous DNA methylation changes happen, and the rate of these changes is many orders of magnitude higher than...

23. Why extra-genetic inheritance is a platypus

...and what we can do about it. In my talk I will take a look at the history of science and outline that extra-genetic inheritance is a classic Duhem-Quine problem. I will explain why the representation of extragenetic inheritance as a fairy-tale organism with apparently incompatible characteristics (like a platypus) can contribute to understanding the current debate about its relevance. I...

24. Spatial heterogeneity induces selection on a system of adaptive epigenetic induction

Evidence that non-genetic traits can be transmitted to future generations has caused a surge in interest in epigenetic inheritance. If it were found to be common across species that adaptive traits acquired during an organism’s lifetime can be passed on to future generations it would prompt a rethinking of evolutionary theory. Yet solid evidence for epigenetic changes being both adaptive and...

Much discussion has recently arisen in relation to the Extended Evolutionary Synthesis to the effect that the Weismann barrier between germ and soma may at times be effectively trespassed by processes of trans-generational epigenetic inheritance and non-genetic inheritance. This is extremely significant as the strict separation between soma and germ and thus the prohibition of the Inheritance...

28. Keynote: Extended Heredity and the Extended Synthesis: An attempt to put recent developments of evolutionary theory into perspective

In recent years it has become increasingly apparent that non-genetic forms of heredity exist in a wide variety of organisms. Furthermore, these “extended” forms of heredity can have interesting and important effects on how evolution by natural selection proceeds. Parallel to these findings has been the development of ideas from evo-devo, niche construction theory, and theory related to other...
