This possibility: an archaeal origin of eukaryotes has been a bit of a distraction in that it has led to models that try and explain eukaryote origins from modern archaea lacking any eukaryotic features. In this talk I will summarise what we know about eukaryote origins, and argue that ways of thinking now more common in palaeontology can help us to understand eukaryote origins. By focusing on known biological processes, and ecological drivers, key events in the origin of eukaryotes can be understood without needing to appeal to special or rare events. 20170516T100000 20170516T110000 Building 54, Room 915 0
