AUSTRALIAN IMMUNOLOGIST
Ted steele; Ted Steele; Meta-Lamarckism

Lamarckism         
  • [[Charles-Édouard Brown-Séquard]] tried to demonstrate Lamarckism by mutilating [[guinea pig]]s.
  • methylation]], enabling a neo-Lamarckian pattern of inheritance for some generations.
  • [[Charles Darwin]]'s [[pangenesis]] theory. Every part of the body emits tiny gemmules which migrate to the [[gonad]]s and contribute to the next generation via the fertilised egg. Changes to the body during an organism's life would be inherited, as in Lamarckism.
  • The long neck of the [[giraffe]] is often used as an example in popular explanations of Lamarckism. However, this was only a small part of his theory of evolution towards "perfection"; it was a hypothetical illustration; and he used it to discuss his theory of heredity, not evolution.<ref name="Ghiselin1994"/>
  • [[Jean-Baptiste Lamarck]] repeated the ancient folk wisdom of the inheritance of acquired characteristics.
  • genera]]. Lamarckism is the name now widely used for the adaptive force.
  • Waddington]]'s [[genetic assimilation]]. All the theories offer explanations of how organisms respond to a changed environment with adaptive inherited change.
  • hologenome]]<ref name="Moran Sloan 2015"/>
  • [[Edward J. Steele]]'s disputed<ref name=Bowler1989Hypermutation/> Neo-Lamarckian mechanism involves [[somatic hypermutation]] and [[reverse transcription]] by a [[retrovirus]] to breach the Weismann barrier to [[germline]] [[DNA]].
  • [[Edward Drinker Cope]]
  • [[Paul Kammerer]] claimed in the 1920s to have found evidence for Lamarckian inheritance in [[midwife toad]]s, in a case celebrated by the journalist [[Arthur Koestler]], but the results are thought to be either fraudulent or at best misinterpreted.
  • Soviet]] agricultural policy in the 1930s.
  • develop]] afresh in each generation from the germ plasm, creating an invisible "[[Weismann barrier]]" to Lamarckian influence from the soma to the next generation.

Edward J. Steele

Edward J. "Ted" Steele is an Australian molecular immunologist with interests in virology and evolution. He is an honorary research associate at the C.Y.O'Connor ERADE Village Foundation in Piara Waters, WA, Australia.

Steele was also the subject of a dispute in 2001–2002 with the University of Wollongong, which led to his widely publicized dismissal, court-ordered reinstatement and subsequent undisclosed financial settlement by the university.

Steele is a proponent of the panspermia hypothesis, which suggests that life exists throughout the Universe.
