ABSTRACT Background: The Wnt signaling pathway is uniquely metazoan and used in many processes during development, including the formation of polarity and body axes. In sponges, one of the earliest diverging animal groups, Wnt pathway genes have diverse expression patterns in different groups...

The plant vascular system transports water and nutrients, but also regulatory molecules that function in short- and long-distance mechanisms to pattern surrounding tissues. As such, the development of the vascular system is tied to the overall patterning and development of the plant body. The...

Abstract: Sponges (Porifera) are abundant in most marine and freshwater ecosystems and as suspension feeders they play a crucial role in filtering the water column. Their active pumping enables them to filter up to 900 times their body volume of water per hour, recycling nutrients and coupling a...

Palmer, A.R.

Two recent studies in BMC Biology and Evolution raise important questions about a textbook case of frequency-dependent selection in scale-eating cichlid fishes. They also suggest a fascinating new line of research testing the effects of handed behavior on morphological asymmetry.

Sponges (Porifera) are among the earliest evolving metazoans. Their filter-feeding body plan based on choanocyte chambers organized into a complex aquiferous system is so unique among metazoans that it either reflects an early divergence from other animals prior to the evolution of features such...

Abstract The sponge reefs, found only off the coast of British Columbia, Canada, are a unique and alien deep sea ecosystem that is not well understood and is threatened by human activities. Here I developed a genetic barcode to differentiate between the two most common sponges on the reefs,...

The genomes of non-bilaterian metazoans are key to understanding the molecular basis of early animal evolution. However, a full comprehension of how animal-specific traits such as nervous systems arose is hindered by the scarcity and fragmented nature of genomes from key taxa, such as Porifera....
