Description

A vast number of approaches have been suggested in the search for selection, ranging from genomic‐based signatures of recent or ongoing selection, tests based on either excessive amounts or nonrandom patterns of divergence (in both fossil sequences and with functional genomics data) and the more classical Lande‐Arnold fitness estimates (direct association of phenotypic values with fitness estimates) and their modern extensions. This workshop presents an integrated overview of all these approaches.

Full attendance and active participation

Information

When?
September 6 to 10, 2021

Morning discussion 8:00-9:30 / Afternoon discussion 15:00-16:30

Where?
Online

We will adopt an hybrid setting for the course, see below


How?

Participants (on their own time) watch a total of three lectures for each day of discussion (6-10.09.2021), where we discuss two in the morning and one in the afternoon. These lectures will all be posted about a week before the course starts, so that students can begin to watch them on their own schedule ahead of the course. It will also include a welcome lecture and hints about how to watch the online lectures.The discussion format will be around 45 minutes of general questions, a 5 minute break, and then 30 minutes in breakout rooms (focused on specific questions/problems) with a general 10 minute discussion afterwards.
