Abstracts

PL

Łuskonośne to jedna z największych grup współczesnych kręgowców. Przez wiele lat jej systematyka wydawała się dobrze ustalona, jednak zaawansowane badania molekularne prowadzone w XXI wieku sugerują zupełnie odmienny jej obraz. Tradycyjne dane morfologiczne wskazują, że łuskonośne obejmują dwie główne grupy - Iguania i Scleroglossa. Z kolei według badań molekularnych Iguania są zagnieżdżone głęboko wewnątrz Scleroglossa i blisko spokrewnione z zupełnie odmiennymi morfologicznie waranami, padalcami, czy wężami. Wskazywałoby to na ogromną konwergencję w morfologii lub sekwencjach genów pomiędzy różnymi grupami łuskonośnych i ich krewnych.

Squamates are one of the largest groups of extant vertebrates. For many years, their systematics seemed to be well established, yet comprehensive molecular genetics analyses conducted in the XXI century suggest completely different picture of the squamate phylogeny. Traditional morphological data suggest that squamates comprise two main groups - iguanians and scleroglossans. However, molecular data imply that iguanians are deeply nested within Scleroglossa and most closely related to squamates of strikingly different morphology such as monitor lizards, slow worms and snakes. This would suggest a huge amount of convergence either in morphology or gene sequences between many groups of squamates and their closest relatives.
