The life cycles of eukaryotes alternate between haploid and diploid phases, which are initiated by meiosis and gamete fusion, respectively. In both ascomycete and basidiomycete fungi and chlorophyte algae, the haploid-todiploid transition is regulated by a pair of paralogous homeodomain protein encoding...

Many modern amphibians have biphasic life cycles with aquatic larvae and terrestrial adults. The central questions are how and when this complicated ontogeny was established, and what is known about the lives of amphibians in the Paleozoic. Fossil evidence has accumulated that sheds light on the ...
It is widely held that the bilaterian tubular gut with mouth and anus evolved from a simple gut with one major gastric opening. However, there is no consensus on how this happened. Did the single gastric opening evolve into a mouth, with the anus forming

An overall brief summary of microstructural evolution is given in Table 5.5. The microstructural evolution is a strong function of various FSW process parameters that influence the thermal cycle. The recrystallized grain size is typically in the range of 1–10 µm. By carefully controlling the pr...
Life, living matter and, as such, matter whose attributes include responsiveness, growth, metabolism, energy transformation, and reproduction. Each individual is composed of one or more minimal living units, called cells, and is capable of transformation
animals and fungi. We show that species in this clade have diverged towards either a fungal-like closed mitosis or an animal-like open mitosis, probably to support distinct multinucleated or uninucleated states. Our results indicate that multinucleated life cycles favour the evolution of closed ...
Island faunas can be characterized by gigantism in small animals and dwarfism in large animals, but the extent to which this so-called ‘island rule’ provides a general explanation for evolutionary trajectories on islands remains contentious. Here we us
