Generative grammarians typically advocate for a rationalist understanding of language acquisition, according to which the structure developed faculty reflects innate guidance rather t...

The study examined the growth characteristics of Siberian spruce (Picea obovata Ledeb.) under canopy coniferous forests in early ontogeny. We revealed that undergrowth adverse conditions is suppressed, slow to grow and has xylorhizomes. result a significant difference height, age stage ontogeny affects forest’s dynamics. formation xylorhizomes changes relative dimensions above-ground part plant...

Shell suture obliteration (ankylosis) was exceptionally frequent in the earliest turtles, contrast to post-Triassic taxa. Since modern turtles grow mostly along sutures, early ankylosis Triassic taxa is intriguing. The turtle Proterochersis porebensis Szczygielski & Sulej, 2016 known from numerous specimens, allowing observation of shell microstructure changes during ontogeny. occurred seem...

Knowledge about vocal ontogeny and vocal plasticity during ontogeny in primate species is central to understanding the evolution of human speech. Vocalizations in gibbons (Hominoidea) are very interesting and contain complex species- and sex-specific patterns. However, ontogeny of gibbon songs is little studied. Here, we document regular production and ontogenetic changes of female-specific "gr...
