occur, as was clearly brought out in the Drosophila pseudoobscura experiments of Dobzhansky and associates14-16 where drift, occasioned by the fact that only a small proportion of possible recombinants is represented in finite populations, was demonstrated. Our results also suggest that an assumption of indeterminism within experimental populations should not be taken lightly where genotypic variability has not been carefully controlled or not investigated to determine its adequacy to explain…

Fine structure of eyespots in tornarian larvae (Phylum: Hemichordata)

The tornarian ocellus studied is compared with eyespots of other invertebrates, and the evolutionary significance of its putative photoreceptors is discussed.

Hydromedusan Photophysiology: An Evolutionary Perspective

For many groups of simple invertebrates, and particularly cnidarians, there has been insufficient information to begin to examine the correlation between the degree of structural complexity and photoreceptor function, revealed either by its photophysiology or by the behavior of the animal.

Amphioxus photoreceptors - insights into the evolution of vertebrate opsins, vision and circadian rhythmicity.

How the available information on photoreceptive organs and light-guided behavior in amphioxus helps generate hypotheses about the history of these features during chordate and subsequently vertebrate evolution is considered.

Fine structure of the neuromuscular system of Polyorchis penicillatus (Hydromedusae, Cnidaria)

The basal portions of the cells of the endoderm canals form a muscle band which might enable the animal to regulate the flow of materials or could perform peristalsis.

Evolution of Photoreceptors

This essay will endeavor to demonstrate the relevance to photoreceptors of the Darwinian dictum: descent with modification to animal and plant photoreceptor structures.

Ocelli in a Cnidaria polyp: the ultrastructure of the pigment spots in Stylocoronella riedli (Scyphozoa, Stauromedusae)

Although the polyps of S. riedli show no distinct reaction to light stimuli, the ultrastructural results corroborate the hypothesis that these organs are light-sensitive organs.

Structure of Invertebrate Photoreceptors

Every explorer is thrilled by the unique and the beautiful. How great must have been the wonder of the first men to view the Grand Canyon of the Colorado, Victoria Falls, Fujiyama on a brilliant

Atlas of the Neuromuscular System in the Trachymedusa Aglantha digitale: Insights from the advanced hydrozoan

The data uncovered the complex organization of neural networks forming a functional ‘annulus-type’ central nervous system with three subsets of giant axons, dozen subtypes of neurons, muscles and a variety of receptors fully integrated with epithelial conductive pathways supporting swimming, escape and feeding behaviors.

Fine structure of the optic cusion in the asteroid Nepanthia belcheri

The optic cushion of Nepanthia belcheri (Perrier) is a prominent pigmented sense organ situated on the oral surface below the terminal tentacle. The distal region contains up to 170 optic cups,
