Hello, I need help answering number 5 questions using the phylogeny below pls & thank you! 5.a) In the 1990s, when only mitochondrial DNA sequencing was available, geneticists claimed that there was no hybridization between humans (Homo sapiens) and Neanderthals (Homo neanderthalensis). Does the phylogeny shown above support the claim humans did not hybridize with Neanderthals in the past? How can you tell? b) Once nuclear DNA sequencing became fast and able to handle sequencing ancient DNA, living humans were found to have some Neanderthal genes. Is this finding clear evidence that some early modern humans did indeed hybridize with Neanderthals? Why? c) Did female H. sapiens hybridize with Neanderthal males to produce fertile offspring that then back-crossed with modern humans? What does the graph say about this? d) Did male H. sapiens hybridize with Neanderthal females that then back-crossed with modern humans? What does the graph say about this? Picture reference:…
Find a current, credible phylogenetic tree representing any group of organisms (your choice)! Draw that tree and on it indicate nodes, synapomorphes, monophyletic, polyphyletic, and paraphyletic groups (make sure the image you choose is complex enough to show all these groups). Below your drawing, in paragraph form, describe the relationships of four of the members on your tree based on how a phylogenetic tree is interpreted

10. Taxonomy versus Phylogenetics For novice biologists, taxonomy and phylogenetics are difficult concepts to understand and keep separate. This confusion is made worse because modern taxonomic methods make use of molecular tools. Write an essay that contrasts taxonomy to phylogenetics and explain how both disciplines are important to our understanding of species and evolution. Your essay should include a description of taxonomy and phylogenetics, as well as a detailed explanation about how information is represented in a phylogenetic tree or a cladogram. It may help you to frame your argument if you start by constructing a paragraph for yourself that says: "Before reading my paper, my reader will think X. After reading my paper, my reader will think y."
