This figure shows a phylogenetic tree of Zika virus sampled in people in Polynesia and Latin America. The tree is turned 90 degrees so that the branches are vertical instead of horizontal, but that is just a style preference of the authors. The branch lengths of the phylogenetic tree are scaled by time (time is on \( y \)-axis), the tips are positioned at their sampling date. Zika virus was sampled in Polynesia in 2013-January 2014 and these Polynesian samples are indicated in grey. Zika virus was sampled in various South and Central American countries in 2015-2016 and these Latin American samples are indicated in color. From this phylogenetic tree, when was Zika virus estimated to have emerged in South and Central America (including Brazil, Caribbean)? Early 2013 Early 2014 Mid 2016 Mid 2015 Question 34 (1 point) Consider this published phylogenetic tree of HIV-1 (Human Immunodeficiency Virus) trains M/A, M/B, N and O, and several SIVcpz strains (Simian Immunodeficiency /irus of chimpanzees). Don't mind the colors. Which of the following is an accurate statement of relationships? HIV-1 \( \mathrm{O} \) is more closely related to SIVCpzTAN1 than to \( \mathrm{HIV}-1 \mathrm{M} / \mathrm{A} \). The different HIV-1 strains (HIV-1 M/A. HIV-1 M/B, HIV-1 N and HIV-1 O) form a monophyletic group that uniquely infects humans. The HIV-1 M/A - HIV-1 M/B clade and the HIV-N clade are each more closely related to particular chimpanzee-borne SIVcpz strains than they are to each other. HIV-1 M/A and HIV-1 M/B are more closely related to HIV-1 N than to any chimpanzee-borne SIVcpz strain. Cane toads were introduced by people in Australia in 1935. Toads that are able to jump farther and longer are able to colonize more new areas, consequently experience less competition from other toads, and therefore have better survival chances. Whether or not the Australian cane toad population will evolve to on average jump farther and longer, will depend on: Whether or not the trait to jump farther and longer is physiologically more complex. Whether or not cane toads will consciously realize it is advantageous to jump farther and longer. Whether or not cane toads have already reached their maximum ability to jump farther and longer before they arrived in Australia. Whether or not the trait to jump farther and longer is heritable.
