We will sequence the entire DNA (genomes) and proteins (proteome) of Mungo Man (Willandra), the Yidinji King (Cairns), the Deep Skull (Borneo) and the Bewah specimen (Malaysian Peninsula). This will provide a better understanding of the settlement of Australia and new knowledge about the ancient people of Australasia and their relationship to other human populations worldwide. The research will use cutting-edge methods of DNA and protein sequencing of ancient human material and will provide critical reference genomes / proteomes that will anchor future research.Read moreRead less
Genetic architecture and evolution of complex traits across populations. Most human traits have a genetic component and display substantial diversity within and among populations. How natural selection changes and maintains genetic variation in human traits is a long-standing question in evolution that the proposed project aims to answer. Using innovative statistical methods and largest genomic “big” datasets ever across populations of different ancestral backgrounds, this project expects to gen ....Genetic architecture and evolution of complex traits across populations. Most human traits have a genetic component and display substantial diversity within and among populations. How natural selection changes and maintains genetic variation in human traits is a long-standing question in evolution that the proposed project aims to answer. Using innovative statistical methods and largest genomic “big” datasets ever across populations of different ancestral backgrounds, this project expects to generate new knowledge on the roles of natural selection in shaping the genetic variation in traits and identify key factors that drive the differentiation of human populations. These outcomes will significantly improve our understanding on the evolution of human traits and adaptation of populations to changing environments.Read moreRead less
The origins of Australia's non-Pama-Nyungan speaking people. This project aims to test the likelihood of multiple migrations into Australia before European arrival and determine if the phylogenetic relationships among non-Pama-Nyungan languages is mirrored by their speakers’ genomic phylogenetic relationships. The non-Pama-Nyungan First People of Australia speak an extraordinary number and diversity of Aboriginal languages, but the origins of these languages and the genomic diversity of the peop ....The origins of Australia's non-Pama-Nyungan speaking people. This project aims to test the likelihood of multiple migrations into Australia before European arrival and determine if the phylogenetic relationships among non-Pama-Nyungan languages is mirrored by their speakers’ genomic phylogenetic relationships. The non-Pama-Nyungan First People of Australia speak an extraordinary number and diversity of Aboriginal languages, but the origins of these languages and the genomic diversity of the people who speak them are only now starting to be understood. There is a remarkable concordance between the Pama-Nyungan languages and the genomic diversity of their speakers. This research could show whether genomes change languages or vice versa, or whether they evolve together over time.Read moreRead less
The nature of standing genetic variation. This project aims to expand understanding of the genetic variation underlying phenotypic differences among individuals. The nature of genetic variation has broad consequences across biology, from the detection of causal genetic variants to the adaptation of natural populations. This project will take a novel experimental approach to test several long-standing assumptions about the effects of new mutations on individual traits and their joint pleiotropic ....The nature of standing genetic variation. This project aims to expand understanding of the genetic variation underlying phenotypic differences among individuals. The nature of genetic variation has broad consequences across biology, from the detection of causal genetic variants to the adaptation of natural populations. This project will take a novel experimental approach to test several long-standing assumptions about the effects of new mutations on individual traits and their joint pleiotropic effect on fitness. By expanding our understanding of how mutation, selection and drift interact, this project could provide significant improvements in our understanding of the genetic basis of phenotypes, and our ability to predict phenotypic evolution.Read moreRead less

Summary
Genes, reproduction and inheritance in a microbe. The project aims to particularly explore sexual gene inheritance in Plasmodium, a representative of a large group of human and animal parasites. Plasmodium must have a sexual exchange of genes in the mosquito for the transfer of disease to a new host. This project will investigate the fate and behaviour of Plasmodium genes during reproduction; the differing chromosome states resulting from sexual genetic processes and the asymmetrical inheritance ....Genes, reproduction and inheritance in a microbe. The project aims to particularly explore sexual gene inheritance in Plasmodium, a representative of a large group of human and animal parasites. Plasmodium must have a sexual exchange of genes in the mosquito for the transfer of disease to a new host. This project will investigate the fate and behaviour of Plasmodium genes during reproduction; the differing chromosome states resulting from sexual genetic processes and the asymmetrical inheritance of some Plasmodium genes. The project is expected to advance Australia’s ability to understand the reproduction and survival of these parasites in their mosquito vector and develop cutting-edge genetic tools that will advance the microbial genetics discipline globally. This may ultimately lead to biotechnology and biomedical outcomes.Read moreRead less

This project aims to develop and apply novel statistical methods to quantify the effects on a large number of complex traits of two forms of non-random mating in humans, that is inbreeding and assortative mating. The innovation in this proposal lies in integrating multi-level phenotypes with next-generation sequencing data collected in more than half a million study participants. Expected outcomes of this research include advanced analytical methods to perform this integration and dissection of the biological consequences of non-random mating in humans at an unprecedented phenotypically detailed scale. The benefit of this project will be to identify new drivers of mate choice that can contribute to economic, health and social inequalities. Read moreRead less
Control of vascular form and fate by a novel pre-mRNA splicing mechanism . Vertebrate vasculature forms elaborate, branched networks essential for life.

Vertebrate vasculature forms elaborate, branched networks essential for life. As developing vessels permeate tissues and organs, dynamic and spatiotemporally regulated cellular signalling determines the fate, patterning and distribution of new vascular networks. This project follows the recent discovery of a mechanism whereby RNA diversification through alternative splicing controls complex signalling patterns in forming vessels. This project investigates this molecular mechanism in embryo and tissue development. The project will produce fundamental knowledge in RNA diversification, vascular fate, growth and cell signalling. New knowledge generated may lead to new approaches in stem cell biology, tissue engineering and regenerative biology.Read moreRead less

The genetic link between local adaptation and speciation. Darwin believed that natural selection drove the origin of new species, or speciation. However, research on speciation during the 20th century shifted focus from studying adaptation within a population to examining the causes of reproductive isolation (lack of interbreeding) between populations. This Project aims to unify our understanding of adaptation and reproductive isolation by examining their shared heredity.

However, research on speciation during the 20th century shifted focus from studying adaptation within a population to examining the causes of reproductive isolation (lack of interbreeding) between populations. This Project aims to unify our understanding of adaptation and reproductive isolation by examining their shared heredity. Using an established system in natural conditions, this project will generate new knowledge on the genetic processes driving speciation. This interdisciplinary research will clarify how biodiversity originates with implications for crops, conservation biology and species responses to environmental change.Read moreRead less
