Domain-general mechanisms, on the other hand, are proposed to deal with evolutionary novelty.
The acquisition of symbiotic organisms, however, is a source of evolutionary novelty, and she is happy to produce a living example.
These names were in use in Darwin's youth, but the origins of the evolutionary novelty and diversity they represent were still big problems then.
Symbiosis, an interdependent relationship between two species, is an important driver of evolutionary novelty and ecological diversity.
Until recently it was believed that "genetic and fossil data support the hypothesis that digits are evolutionary novelties".
Eukaryotes have maintained their introns because they confer the capacity to create evolutionary novelty through exon shuffling [ 2 ] .
The way evolutionary novelties start is an important topic.
They are considered the most complex integumentary structures found in vertebrates, and indeed a premier example of a complex evolutionary novelty.
Human trichromatic color vision is a recent evolutionary novelty that first evolved in the common ancestor of the Old World Primates.
Most neo-Darwinians consider epigenetic inheritance mechanisms to be little more than a specialized form of phenotypic plasticity, with no potential to introduce evolutionary novelty into a species lineage.
