Human embryo in vitro: a processual entity in legal stasis

This paper is intended to provide a history of the field and some of the techniques used, as well as some suggestions for future research, which are currently being developed.

Experimental Studies on Germinal Localization (1904), by Edmund B. Wilson [1]

Biologists proposed various versions of the theory of germinal localization in the decades following His's work, arguing that substances are unequally distributed throughout the cytoplasm of the egg, and that the eventual production of tissues and organs can be traced back to those distributions.

Use of Artemia as model organism to study epigenetic control of phenotypes relevant for aquaculture species

Interestingly, overall results leave no doubt on the role of epigenetic modifications, such as DNA methylation, histone H3 and H4 acetylation and H3K4Me3 on emergence of these new phenotypes.

The holist tradition in twentieth century genetics. Wilhelm Johannsen's genotype concept

This paper shows how Johannsen's holistic genotype theory provided a platform for criticism of narrowly genocentric versions of the chromosome theory of heredity that came to dominate genetics in the middle decades of the twentieth century.

The Riddle of Sex: Biological Theories of Sexual Difference in the Early Twentieth-Century

This paper will illustrate how the older metabolic theory of sex was displaced when those who argued for the relatively newer theories of chromosomes and hormones gradually formed an alliance that accommodated each other and excluded the metabolic Theory of sex.

It is argued that historical considerations need to be included as part of the use and critical assessment of basic concepts in science, including the potential for conceptual distortions due to historical factors.
