Identifying the genes and population histories that drive rapid adaptive change and speciation. This project will uncover the genetic variation and demographic histories that allow rapid adaptation and speciation in natural populations. It will leverage the powerful framework provided by Indo-Australian sea snakes, and new gene sequencing technologies, to reconstruct the evolutionary histories of genes, populations and species.

This project will uncover the genetic variation and demographic histories that allow rapid adaptation and speciation in natural populations. It will leverage the powerful framework provided by Indo-Australian sea snakes, and new gene sequencing technologies, to reconstruct the evolutionary histories of genes, populations and species. Using this data, it will address inter-related key questions that are critical to effective biodiversity conservation but have rarely been evaluated in the same taxon. It will address what genetic changes are involved in adaptive shifts and speciation, whether these originate de novo or from pre-existing variation and how gene flow and changes in population size promote or constrain adaptation and speciation.Read moreRead less
Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and gene ....Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and genetics to address questions such as how and why ancestral macropods descended from the trees and evolved bipedal hopping, and the upper size limits of the kangaroo “body plan”. This should improve our understanding of the long-term effects of climate change on marsupials, and provide a test of key placental-based evolutionary models.Read moreRead less
