Накратко на български

Педоморфозата при бръмбарите е явление, при което възрастните насекоми запазват белези от младостта си. Анализът на тези промени помага да се разбере как се развиват сходни външни характеристики при различни животни.

How Paedomorphosis shapes Animal Phenotypes Evolution: A Case Study Using Beetles

The paedomorphosis syndrome (PDM) is a phenomenon in which individuals retain juvenile traits or features into adulthood, resulting in a resemblance of adults with their young forms. Overall, our knowledge about the effects and causes of the PDM in animals is fragmentary. In beetles, the PDM has evolved multiple times in several unrelated lineages, such as fireflies and click-beetles. Our knowledge about the effects and causes of PDM in beetles is as fragmentary as in animals in general. It is currently unknown whether the paedomorphic modifications in different beetle lineages have the same evolutionary origins or if they have evolved independently. These gaps negatively impact our understanding of how PDM shapes the evolution of organisms. This study aimed to (1) Identify and document morphological changes in paedomorphic lineages across the Coleoptera, 2) Test hypotheses of homology for morphological characters heavily affected by PDM in a phylogenetic framework using beetles of the tribe Calopterini (Lycidae) as example, and 3) Identify evolutionary causes for the repeated and independent development of PDM in beetles as a model to understand convergent phenotypes in animal evolution.

Цел на проекта

Paedomorphosis is a poorly understood phenomenon in evolutionary biology in which juvenile traits of an organism are retained into adulthood. The evolutionary origins of, and driving forces behind, various cases of paedomorphosis in animals remain unknown. Exploring cases of paedomorphosis across the entire animal kingdom is a desired but overwhelming task, but beetles, a mega-diverse insect order with numerous paedomorphic lineages, is the best proxy to study this phenomenon within a manageable project and with high potential for broad extrapolations. With this project, I propose to (1) document the morphological changes in paedomorphic lineages across beetles to (2) test hypotheses of morphological homology for paedomorphic characters in a phylogenetic framework using genomics and to (3) identify evolutionary causes behind the repeated development of paedomorphosis. I expect the results to be scalable and thus instrumental in generating an inclusive theory of the repeated origin of paedomorphosis across the entire animal kingdom. Through my past research I developed a unique systematic knowledge of the elateroid beetles where paedomorphosis occurs with high frequency. The implementation of this project will raise me from a domain-restricted entomologist to an independent successful evolutionary biologist and thus maximize my chances for a tenure track position in a world-class research institution in Europe. Dr. Alexey Solodovnikov, my host at Copenhagen University, works with current integrative methods in systematic entomology, fundamental to the successful development of my ideas on paedomorphosis.
