Variation in DNA content has been largely ignored as a factor in evolution, particularly
following the advent of sequence-based approaches to genomic analysis. The significant …

Understanding the diversification of phenotypes through time—“descent with modification”—
has been the focus of evolutionary biology for 150 years. If, contrary to expectations …

Research into the lives of animals in their natural environments has revealed a rich tapestry
of complex social relationships and previously unsuspected social and mating systems. The …

In this paper, we present Salamandra robotica II: an amphibious salamander robot that is
able to walk and swim. The robot has four legs and an actuated spine that allow it to perform …

Controversy surrounds the apparent rising maximums of morphological complexity during
eukaryotic evolution, with organisms increasing the number and nestedness of …

Publisher Summary This chapter focuses on genomic size evolution in animals. There are
many ways of studying the evolution of genome. The chapter looks on the examination of …

For many years the mammalian CNS has been seen as an organ that is unable to
regenerate. However, it was also long known that lower vertebrate species are capable of …

Accumulation of noncoding DNA and therefore genome size (C-value) may be under strong
selection toward increase of body size accompanied by low metabolic costs. C-value directly …

Haploid genome size (C-value) is correlated positively with cell size, and negatively with cell
division rate, in a variety of taxa. Because these associations are causative, genome size …

Among vertebrates, most of the largest genomes are found within the salamanders, a clade
of amphibians that includes 613 species. Salamander genome sizes range from∼ 14 to∼ …
