Forradalmi megközelítése és új szemlélete a matematikai biológia volt, azaz a matematika alkalmazása a biológiában. A fizikai erők és törvények működését a biológiai rendszerek fejlődésében egyenrangú hatóként kezelte a darwini természetes szelekcióval, felhívva a figyelmet arra, hogy számos biológiai forma és kifejlődés megértéséhez szükségtelen a természetes szelekciót segítségül hívni. Manapság elmélete az evolúciós fejlődésbiológia alapműve, és számos kutatási irány gyökere Thompson műveiben keresendő. Hatása túlmutat a tudományon: szobrászok, festőművészek, építőmérnökök, sőt, még a mesterséges intelligencia arcfelismerő programjai is merítenek belőle, ősforrásuknak tekintik.

Rarely observed structures in the upper lamellar layers of the studied laevaptychi revealed 24–32 concentric lamellae that represent primary textural features and indicate excellent preservation. After careful screening for diagenetic effects, stable oxygen isotope compositions yielded seawater temperatures between 20 and 26 °C in good agreement with earlier studies on Jurassic formations, with improved precision.

In the SE direction from the volcanic edifice at Zengővárkony, a shallow marine (depth 100–200 m) carbonate sediment hosted a vent environment, and iron ore deposition occurred at the end of the Valanginian to early Hauterivian, hosting a diverse, endemic fauna of approximately 60 species. The detailed mineralogical analysis of the transport conduits included Fe oxides (ferrihydrite, goethite, hematite, and magnetite), quartz, mixed carbonate, pyrite, feldspar, Fe-bearing clay minerals, apatite, sulfates (barite, gypsum, and jarosite), and native sulfur. Filamentous, microbially mediated microtextures with inner sequented, necklace-like spheric forms (diameter of 1 μm) and bacterial laminae are also observed inside decapod crustacean coprolites (Palaxius tetraochetarius) and in the rock matrix. This complex ecological and mineralogical analysis provided direct evidence for the presence of bacteria in fossil sediment-hosted vent (SHV) environments on the one hand and for the intimate connection between bacteria and decapod crustaceans in hydrothermal environments 135 Ma before.

Carnivorous diet appeared on Earth slightly before the information behaviour as a completely new way of feeding – and what is more important: the application of light into the behavioural complexes as a radically innovative survival supporting tool. A genetic toolkit was ready for Metazoa, and the combination of the neural system, eyesight and carnivorous diet initiated the information behaviour.
