In modern terms, this transmission from parent to offspring could be considered a method of epigenetic inheritance. Scientists are now questioning the framework of the modern synthesis, as epigenetics to some extent is Lamarckist rather than Darwinian. While some evolutionary biologists have dismissed epigenetics' impact on evolution entirely ...
Epigenetic mechanisms. In biology, epigenetics is the study of heritable traits, or a stable change of cell function, that happen without changes to the DNA sequence. [1] The Greek prefix epi-(ἐπι-"over, outside of, around") in epigenetics implies features that are "on top of" or "in addition to" the traditional (DNA sequence based) genetic mechanism of inheritance.

Transgenerational epigenetic inheritance is the proposed transmission ... do changes in epigene frequencies constitute evolution? Rapidly decaying epigenetic effects ...
New types of inheritance, including cultural and epigenetic inheritance. [55] [56] The way that organismal development and developmental plasticity channel evolutionary pathways [57] [41] [43] and generates phenotypic novelty [48] [49] [58] How organisms modify the environments they belong to through niche construction. [5] [2]
From position and maternal effects on gene expression to epigenetic inheritance [6] to the active construction and intergenerational transmission of enduring niches, [3] development systems theory argues that not only inheritance but evolution as a whole can be understood only by taking into account a far wider range of ‘reproducers’ or ...
In 1977, a revolution in thinking about evolution and developmental biology began, ... epigenetic inheritance, genetic assimilation, niche construction and symbiosis.
J. Bruce Walsh was skeptical of Jablonka's claims in the book Epigenetic Inheritance and Evolution regarding the importance of epigenetic inheritance in evolution. [11] R. J. Berry, however, wrote that the book made a strong case for the importance of epigenetic inheritance in evolution and recommended the book for evolutionary biologists. [12]
In 2008, Jablonka and Lamb published the paper Soft inheritance: Challenging the Modern Synthesis which claimed there is evidence for Lamarckian epigenetic control systems causing evolutionary changes and the mechanisms underlying epigenetic inheritance can also lead to saltational changes that reorganize the epigenome.
