A new universal mechanism controlling body proportions in animals. This project aims to establish that a recently-discovered mechanism, the inhibitory cascade, determines the basic proportions of appendages and body segments in a diverse range of animal groups, particularly vertebrates and arthropods. The goals of the project are to reveal the molecular mechanisms in mice and insects, and build computer simulations to show how to manipulate the control of development by the inhibitory cascade.

The goals of the project are to reveal the molecular mechanisms in mice and insects, and build computer simulations to show how to manipulate the control of development by the inhibitory cascade. The project should benefit bioengineering by establishing control mechanisms for the manipulation and regeneration of teeth and limbs.Read moreRead less

Summary
Using sponge transcriptomes to understand ancestral animal development. The invention of a basic developmental program was likely a key step in the transition to multicellularity in animals, one of the major transitions in the tree of life. By combining next-generation sequencing of a representative panel of sponges and functional studies on an oviparous sponge, this project aims to identify gene interactions and networks that built the first animal embryos over 680 million years ago.

The invention of a basic developmental program was likely a key step in the transition to multicellularity in animals, one of the major transitions in the tree of life. By combining next-generation sequencing of a representative panel of sponges and functional studies on an oviparous sponge, this project aims to identify gene interactions and networks that built the first animal embryos over 680 million years ago. Furthermore, the role of Wingless (Wnt) signalling in patterning these ancestral embryos along a primordial anterior-posterior axis will be investigated. Piecing together the fundamental molecular machinery shared by all animal embryos will shed light on the molecular basis for the complex development of most animals on Earth.Read moreRead less
Evolutionary origin of stem cells and the emergence of animal complexity. The project aims to decipher the fundamental mechanisms governing stem cell specification and formation. All animals rely on stem cells to replenish, repair and regenerate tissues. Stem cells are also often a conduit to malignant tumours. This project seeks to uncover the rules governing stem cell formation through the study of a simple and ancient animal – the marine sponge Amphimedon queenslandica. The project plans to c ....Evolutionary origin of stem cells and the emergence of animal complexity. The project aims to decipher the fundamental mechanisms governing stem cell specification and formation. All animals rely on stem cells to replenish, repair and regenerate tissues. Stem cells are also often a conduit to malignant tumours. This project seeks to uncover the rules governing stem cell formation through the study of a simple and ancient animal – the marine sponge Amphimedon queenslandica. The project plans to combine insights from the simple, experimentally-tractable sponge stem cell system with existing knowledge of stem cell specification in humans and other animals, to reveal the essential features of stem cell formation. These insights may inform future pursuits to generate, control and use stem cells in cancer and regenerative medicines.Read moreRead less
Evolution of environmental regulation of cell states in animal life cycles. This project seeks to understand how the environment influences the fate of cells over an animal's life, and how this influence originated in animal evolution. Using a homegrown Australian model, a sea sponge from the Great Barrier Reef, and advanced multi-omic approaches (genomics plus cell biology), this project aims to uncover the mechanisms underlying global cell state changes that are induced through the interplay o ....Evolution of environmental regulation of cell states in animal life cycles. This project seeks to understand how the environment influences the fate of cells over an animal's life, and how this influence originated in animal evolution. Using a homegrown Australian model, a sea sponge from the Great Barrier Reef, and advanced multi-omic approaches (genomics plus cell biology), this project aims to uncover the mechanisms underlying global cell state changes that are induced through the interplay of environmental and endogenous signals at metamorphosis. Because of the evolutionary position of sponges, outcomes of this project expect to reveal the cardinal rules governing environmentally-induced cell state changes that are obligatory for most animals to complete their complex life cycles.Read moreRead less

Summary
How did mammals evolve large brains? A multidisciplinary view from the pouch. This project applies novel data collection techniques to explain how the large brain sizes of today's mammals (including humans) are possible. The focus will be on brain structure, development, and evolution in the mostly Australian marsupials, whose ancestral mode of brain development makes them an ideal group for studies of brain size evolution.
