After multiple complaints, the United States Food Safety and Inspection Service obtained hamburger samples from Peat's Patties (Peat's Sample A and Peat's Sample B), extracted the DNA from the meat, conducted genetic sequencing and used the resulting sequences, along with DNA sequence data from other animals, to build a phylogeny that shows the relationship of Peat's Patties meat to other animals. Use the phylogeny below to determine if Peat's Patties is guilty of using alternative meat sources in their burgers. Bison Cow Goat Sheep 2.

- Which of the following is FALSE regarding phylogenetic trees? 1) The branch lengths on the tree are scaled to molecular (DNA) changes and/or time. 2)Phylogenetic trees have shown us that there is much more bacterial diversity compared to eukaryotes. 3) Phylogenetic trees show the evolutionary relatedness of different organisms. 4). The branch lengths on the tree depict abiotic and biotic factors affecting speciation.arrow_forwardWhat is adaptive radiation?
