Lake Tanganyika in Africa is a true hotspot of organismal diversity. Approximately 240 species of cichlid fishes have evolved in this lake in less than 10 million years. A research team from the ...

Evolution, Vol. 70, No. 7 (JULY 2016), pp. 1559-1568 (10 pages) Brain size is strongly associated with body size in all vertebrates. This relationship has been hypothesized to be an important ...

This is a preview. Log in through your library . Abstract The morphological diversity of Malawi and Tanganyika cichlids has often been qualitatively described, but rarely have hypotheses based on ...

A distant star-killing supernova could have bombarded Earth with radiation strong enough to shift the course of evolution.

Cichlid fishes, renowned for their extraordinary speciation and adaptive radiation, provide an exceptional framework to explore evolutionary dynamics, particularly through the study of their parasites ...

Africa’s deepest freshwater lake holds a dizzying array of animals, including hundreds of species of cichlid fish found nowhere else in the world. They crowd the waters of Lake Tanganyika, with scales ...

Biologists shed new light on animal speciation. Animals that have either migrated to or been introduced in Central Europe -- such as the Asian bush mosquito or the Asian ladybeetle -- feel extremely ...

Behavioral laterality, or left- or right-handedness, has been reported in many animals, including humans, chimpanzees, toads, rats, mice, and invertebrates such as crustaceans and insects. Now ...

There are other animals besides the cuckoo who smuggle their offspring into another animal's nest. The synodontis multipunctatus, which occurs in Lake Tanganyika in Africa and is better known as ...
