EVOLUTIONARY TRANSITION FROM AMMONITE SUBPRIONOCYCLUS TO REESIDITES- PUNCTUATED OR GRADUAL?

The Rise of the Modern State: Gradual Reform or Punctuated Transition

A state is not alive, yet it performs many of the central functions of life like replication and adaptation to new conditions to balance social protection and opportunity. As a lifelike system the rise of the modern state raises four sets of fundamental questions about its evolutionary design. A first set concerns how it became a sustainable, autonomously replicating system, capable of evolutio...

From manual gesture to speech: a gradual transition.

There are a number of reasons to suppose that language evolved from manual gestures. We review evidence that the transition from primarily manual to primarily vocal language was a gradual process, and is best understood if it is supposed that speech itself a gestural system rather than an acoustic system, an idea captured by the motor theory of speech perception and articulatory phonology. Stud...

A Gradual Transition: Emerging Adulthood

Is evolution gradual or rectangular? Evidence from living fishes.

The traditional view that most evolutionary change is gradual and cumulative within lineages (phyletic gradualism) has recently been challenged by the proposition that the majority of evolutionary change is concentrated within speciation events (rectangular evolution). The logical implications of these competing hypotheses for the means and variances of genetic distance among living members of ...
