Thanks @llundgren for the summary, and @taorminalepore for the great overview of the skull anatomy terms!
Like Lisa wrote in her summary, I wondered what a “sister group” means? It had been a while since my college evolutionary biology classes, so I did some Googling to review and found a great, short phylogeny overview from UC Berkeley, including a simple sister group diagram: https://evolution.berkeley.edu/evolibrary/article/phylogenetics_02
The authors mention that their phylogenetic conclusions should be viewed with caution, however, due to low bootstrap support. @jbokor, @bmacfadden, @smoran – you were all recommended as people with phylogenetic knowledge, can anyone help explain what that means? Thanks!
