Exploring the sexual diversity of flatworms: Ecology, evolution, and the molecular biology of reproduction.

Flatworms show great diversity in their reproductive biology, making the group an excellent model system to explore how differences between species in reproductive ecology is reflected in the physiological and molecular details of how reproduction is achieved. In this review, I consider five key “lifestyle choices” (ie, alternative evolutionary / developmental outcomes) that collectively Encompass many sexual diversity flatworms, begins with a decision: (i) whether to live free or parasites; (Ii) whether to reproduce asexually or sexually; and (iii) whether it should gonochoristic (separate-sexed) or hermaphrodite.

I then checked two further decisions involving hermaphroditism (iv) outcrossing to selfing and (v) the balance of investments into male versus (allocation sex) female sexual function. Collectively, lifestyle choice, it sets the ground rules for how reproduction occurs, but as I emphasized in the second part of the review, reproductive biology flatworms also heavily influenced by the pressure near-pervasive strong sexual selection, together with the related phenomena of competition sperm and sexual conflict.

Exactly how this plays out, however, strongly influenced by the particular combination of reproductive strategies adopted by each species.
Between November 30 and December 2, 2015, Jacques Loeb Center for History and Philosophy of Life Sciences at Ben-Gurion University of the Negev in Beer Sheva (Israel) organized the Eighth International Workshop titled “From Genome to Gene: causality, Synthesis and evolution”.

Eric Davidson, founder of the concept of development of Gene Regulatory Networks, has regularly attended previous meetings, and participation in this one is expected, but suddenly he died three months earlier. In this paper, we provide an introduction and overview of the five papers presented at the workshop and examine the importance of genome and gene regulatory networks in biology that still exist, developmental biology, evolutionary biology and medicine, as well as a collection of memories of Eric Davidson, personality and contribution scientific. provided a historical perspective, and the ethical issues raised by new tools developed to modify the genome are also discussed.

Dynamic modeling approach based on logic to explain the evolution of the central dogma of molecular biology.

It is almost half a century past the age of introduction of the Central Dogma (CD) of molecular biology. Biological axiom has been developed and now it seems all the more complex. In this study, we modify the CD by adding more species to the flow of information CD and CD expressed mathematically in a dynamic framework using Boolean network based on its present and 1965 editions.

We show that the increase of Dogma is not only now require a higher level of complexity, but also showed a higher level of endurance, so far more consistent with the nature of the biological system. Using mathematical modeling approach, we put forward the expression based on the logic-conceptual perspective of molecular biology. Finally, we show that the biological concepts can be turned into a dynamic mathematical model using logic-based approach and thus may be useful as a framework for improving the static conceptual model in biology.
