Adelie Penguins Population Under Threat Discussion In the videos this week, you learned from people who are intensively studying populations of large wild mammals and trees in Africa. Their stories are dramatic and impressive. There are equally interesting stories right around you, now. Biologists at CSUN...
https://www.researchgate.net/publication/14004004_Endemic_African_mammals_shake_the_phylogenetic_tree 1- why is the order Insectivore important to understanding the phylogenetic relationships with Placental mammals? 2- when do the authors feel that the "African Radiation" occured? 3- looking at the three phylogenies on Figure 1, briefly explain what is being represent here. what is the significance of...
