A semi-popular science book on reproductive genetics: why, you may ask? Because reproduc-tion is the central theme in both biology and evolutionary biology.How can a species persist? The relay baton in the form of the fusion of the egg and sperm cell creates a new generation that gets to run another lap and pass on the baton. What lies behind this metaphor, and how does it work? What are the im…
Over the last two decades, new cell and molecular biology toolshave become available, allowing the exploration of a broader rangeof metazoan regenerative mechanisms and prompting a (re)-expansion of the field of regenerative biology [3, 4]. A unifyingtheory of regeneration is nevertheless still lacking. Why do not allspecies regenerate? Does regeneration have a single or multiple(evolutionary) …
Currently, the origins ofin vitrocell lines are highly biased towards humans.Around 75% of the total number of established cell lines are from Hominidae origin(96,862/128,799) and over 97% are of mammalian origin (126,033/128,799) (Bairoch2018) (Figure 1). However, mammals represent only 0.4% (1.3% when excluding theInsecta taxon) of the extant identified metazoan evolution (Zhang 2013; Wilson …
