The first picture is a question that has already been complete, but you do need to use that first picture to answer to question #2
Below are six faces. Each face represents a species, with Species 6 being the outgroup. Seven characters are listed in the table, along with an ancestral and a derived character state for each character. Please identify the derived characters and complete a character matrix for these species that includes only the derived character states. ancestra Ichracte rs, species → species 1 species 2 species 3 species 4 species 5 round jaw ✓ X X X X Character Neck size Jaw shape Eyebrows Ears 2 small neck ✓ X X Eyes Tail Nose X X 3 Character States Big neck, small neck Round jaw, pointy jaw Angled brow, rounded brow THE ANSWER: ✓ X angled brow human ears X Human ears, cat ears Square eyes, round eyes Tail, no tail Small nose, large nose X X √ ✓ X 5 X ✓ no tail ✓ X ✓ √ 6 ✓ small nose ✓ √ √ X √
