Using the framework of evolutionary lineages to separate the process of evolution and
classification of species, we observe that 'anagenesis' and 'cladogenesis' are unnecessary …

Abstract Aim East Africa is one of the most biologically diverse regions, especially in terms of
endemism and species richness. Hypotheses put forward to explain this high diversity …

Chameleons so easily capture the imagination, and have done so for centuries. In scientific
writings, they first appear with Aristotle (350 BC), and although they were recognized as …

The mechanisms that underpin ecological speciation, morphological convergence and the
evolution of ecological morphotypes (ecomorphs) in squamates have allowed for a better …

Species delimitation within recently evolved groups can be challenging because species
may be difficult to distinguish morphologically. Following the General Lineage Concept, we …

The head is a complex integrated system that is implicated in many vital functions. As such,
its morphology is impacted by different and sometimes conflicting demands. Consequently …

Urbanisation is a major driver of habitat transformation that alters the environmental
conditions and selective regimes of the habitats where it occurs. For species inhabiting …

Interspecific variation in animal form, function and behaviour is often associated with habitat
use, implying co-adaptation. Numerous studies of the 'ecomorphs' of Greater Antillean …

The evolutionary processes that produce adaptive radiations are enigmatic. They can only
be studied after the fact, once a radiation has occurred and been recognized, rather than …

Evidence that morphological traits associated with particular environments are functionally
adapted to those environments is a key component to determining the adaptive nature of …
