11. On Speciation in Birds – Genomic Signatures across Space and Time
Sammanfattning : The process of speciation is a cornerstone in evolutionary biology. In Darwin’s On the Origin of Species, he described how he imagined that a new species would evolve to fill an empty niche. This focus on ecology shifted with Mayr towards the importance of isolation, and for many decades the geographic modes of speciation were debated. LÄS MER
12. The evolution of courtship rituals
Sammanfattning : The fact that many animals engage in highly ornamented and conspicuous display behaviours in connection with reproduction has received much attention in zoology ever since Darwin launched his theory of sexual selection. This thesis intends to investigate the evolution of such display behaviour. LÄS MER
13. Controlling Destiny : Julian Huxley's Post-Darwinian Evolutionism and the History of Transhumanism
Sammanfattning : The evolutionary biologist Julian Huxley (1887–1975) attempted to promote a “religion for the future,” which he would come to refer to as Transhumanism. It was Huxley’s firm belief that mankind needed a unifying system of thought that could motivate action and change. LÄS MER
14. From wolf to dog: Behavioural evolution during domestication
Sammanfattning : Biologists since Darwin have recognized that domestication, where species are selected to live in human-controlled environments, exerts strong selection on organisms and dramatically impacts their evolutionary trajectories. Across domesticated mammal species, characteristic morphological, physiological and behavioural changes occur simultaneously, as correlated traits, a phenomenon known as the domestication syndrome.

15. Evolutionary genetics and consequences of inbreeding in sand lizards (Lacerta agilis)
Sammanfattning : Inbreeding is a well-known phenomenon in evolutionary and conservation biology. In the 19th century, Charles Darwin demonstrated the detrimental effects of inbreeding in plants, followed by over a century of extensive research including various animal and plant taxa. LÄS MER
