Abstract: This paper presents some of the recent challenges to the Modern Synthesis of evolutionary theory, which has dominated evolutionary thinking for the last sixty years. The focus of the paper is the challenge of soft inheritance -the idea that variations that arise during development can be inherited. There is ample evidence showing that phenotypic variations that are independent of variations in DNA sequence, and targeted DNA changes that are guided by epigenetic control systems, are important sources of heredit… Show more

“…The major transitions in evolution (34) seem to have been all crucially influenced by "soft" epigenetic inheritance (35,36). In particular, the role of flexible epigenetic reactivation might be very critical in evolutionary survival of young gene duplicates (18)(19)(20).…”

“…O argumento principal é que a seleção natural de variações genéticas deveria ser complementada pela seleção de outros tipos de variação¹ (Jablonka & Lamb, 2005, 2008b. Além disso, na medida em que todas essas fontes de variação sofrem, em algum grau, influência de processos que ocorrem no interior do próprio organismo e de mudanças ambientais (e, portanto, não são completamente randô-micas), seria legítimo dizer que a experiência ambiental do organismo interfere no processo evolutivo, levando alguns autores a defender que o neodarwinismo poderia ser substituído por um neolamarckismo (Gissis & Jablonka, 2011;Jablonka & Lamb, 2005).…”

“…O primeiro deles é que o processo evolutivo envolveria múltiplas fontes de variações herdáveis sobre as quais a seleção natural operaria (Jablonka & Lamb, 2005, 2008b. Com isso, essa teoria passa a considerar outros sistemas de herança, além do sistema genético.…”

“…Variations in chromatin acetylation and DNA-methylation can influence rates of mutation, transposition, and recombination of DNA. This can provide a bias for change in the DNA sequence (Jablonka & Lamb, 2008). It may provide an explanation for the tendency of the Human Accelerated Regions (HARs) to have biased patterns of DNA nucleotide substitutions (Berglund et al 2009).…”
