You can read more about these results here and here. https://images.squarespace-cdn.com/content/v1/5e200a54c907326f1d50701c/1625691147571-FBQSVSEURAIVZAVBA57E/Timescale.png Research - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/5e200a54c907326f1d50701c/0ace24ed-0318-40e2-a679-4295089cefa1/NEE+Figure+2_edited.jpg Research Eukaryotes apparently evolved “symbiogenetically” via lineages representing each of the two primary domains of life (the Bacteria and the Archaea). Details can be found here. This figure was designed by collaborators Phil Donoghue and Davide Pisani at The University of Bristol. https://images.squarespace-cdn.com/content/v1/5e200a54c907326f1d50701c/1581822059716-0TM2T2DJWK51INZE08T3/complex_multicellularity_plot_DBM.svg.png Research A timeline showing when the six major eukaryotic clades displaying complex multicellularity likely evolved. The horizontal bars represent the highest confidence intervals (95%) for the age of each multicellular clade, as taken from various molecular clock (MC) analyses. The diamonds indicate the mean estimates for the age of each clade. Ma = million years ago. An earlier version of this figure was published here, and a PDF of this version can be downloaded here.
