It has long been thought that dramatic changes in a landscape like the formation of the Andes Mountain range or the Amazon River is the main driver that initiates species to diverge. However, a recent ...

Speciation is a central and fundamental process in evolution that concerns the origin of reproductive isolation. The latest generation of genomic approaches provide remarkable opportunities to ...

Mimicry has had a significant historical influence as a tractable system for studying adaptation and is known to play a role in speciation. Here, we discuss recent theoretical treatment of adaptive ...

New research has uncovered how different populations of the bird crimson rosella are related to each other -- a discovery which has important implications for research into how climate change may ...

Most diploid species have unique polygenic systems; since they are complex and coadapted throughout the genome, their integrity is not easily perturbed. A recent theory calls for the formation of new ...

The strength of mate choice (choosiness) often varies with age, but theory to understand this variation is scarce. Additionally, theory has investigated the evolution of choosiness in speciation ...

The process of speciation allows a single species to diverge into two. Dive into the different versions of this process, including “allopatric speciation” and “sympatric speciation,” and discover how ...

"Supplement to The Auk"--Cover. Differentiation and speciation without extended isolation appear to be common among migratory animals. Historical oversight of this is probably due to temporal ...

German researcher Christian Rabeling was digging up ant colonies on a college campus in Brazil when he found something unexpected—certain ants appeared smaller and shinier and had wings. Rabeling soon ...
