<p class="MsoNormal">From agriculture to urbanization to invasive species, humans have created novel evolutionary challenges for organisms across the globe. Perhaps one of the most widespread of these challenges is climate change, which pushes organisms past
their physiological limits and can result in population decline or local extinction. With the increasing ease of genome sequencing in natural populations, genetic variation associated with climate has been uncovered in a wide variety of systems. Although this
genetic variation represents the raw material needed for organisms to adapt to ongoing climate change, we know little about the relative rates and limits of adaptation. In this talk, I will present frameworks for using population genomics to predict evolutionary
responses to climate change, focusing on two very different taxa – migratory birds and reef-building corals. I will also discuss how evolutionary predictions can be synthesized to inform conservation plans.<o:p></o:p></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">The diversity of life that we see today stems from a single common ancestor and has been ~3.5 billion years in the making. However, the biochemical processes that underlie the functionally diversification of
organisms are poorly understood. To explore the molecular mechanisms governing functional diversification I use evolutionary simulations to examine the relationship between selective pressures, protein biochemistry, and functional change. I find that proteins
maintain the ability to functionally interact with one another over long evolutionary periods even when that function is not being selected for. I also identify key biochemical differences that are indicative of the loss of functional interaction. Further,
when examining how duplicated proteins functionally diversify I have made the unexpected observation that important functional changes frequently happen in non-duplicated proteins that interact with duplicated proteins, rather than in the duplicated proteins
themselves. Interestingly, this finding implies that the mere presences of a duplicate can impact how protein interfaces co-evolve, independent of the fate of a duplicate. Although it is conventionally assumed that duplicate genes acquire novel functionality
due to changes to the gene itself, I demonstrate that these ends can be facilitated by modifications to the original functionality. This finding highlights that concepts of functional gain, change, or loss after duplication need to be studied in the context
of the entire system containing a duplicated gene, not just the duplicated gene by itself.<span style="font-size:12.0pt"><o:p></o:p></span></p>
