Examine the image of the relatedness of vertebrates represented in this phylogenetic tree. Which statements are correctly inferred from this tree? Select all that apply. A) The mammals are the outgroup in this tree. B) Birds and dinosaurs share a recent common ancestor. C) Mammals and birds are more closely related than any other species.

The table shows the distribution of traits (A-E) in six extant species (1-6). A “0” indicates the ancestral condition, and a “1” indicates the derived condition. 1. Which trait is least informative of phylogenetic relationships within the group? 2. Which species has the fewest number of derived characters?
4) Pretend it's a year later, and you have collected more data to make a more detailed phylogeny. You notice that some of these species of birds are sexually dimorphic (males have significantly different plumage than females, generally much brighter!). You also notice that in some of these species both parents feed the offspring, while in others only the female feeds the offspring. You imagine that having bright males near the nest may tend to attract predators to the young. You want to distinguish between two hypotheses to explain the patterns you see: 1) Males not feeding the young is an adaptation to dimorphism 2) If males don’t feed the young in a species, it will allow them to become brightly colored To begin to address this question, map the characters changes in dimorphism and males feeding the young onto each of the trees on the previous page.

(a) How do you describe the data from the amino acid sequence to anatomical features provided in the cladogram? Are they generally associated with one another? (b) do you agree that the more differences in amino acid sequence, the more closely related organisms are, if yes does that mean they shall be group under the same biological classification? (c) in the molecular data provided, describe how human and rhesus monkey relate with one another (d) why do you think 30 and chicken are different species despite the fact that they have the same sequence of amino acids for cytochrome c protein? help plssss, thank u! thank u!
10. Refer to the figure shown. Species Stripe Color 1 2 3 B. C R The figure shows the phylogeny of seven species of beetles (A-G) and whether the beetles have (?) or do not have (x×) one of three stripes. It also indicates the color of the beetle (R for red and G for green). Based on the phylogenetic tree and the principle of parsimony, the absence of stripe in species is most likely O 1; E and F; an evolutionary reversal O 2; E and F; due to convergent evolution O 2; E and F; a synapomorphy O 1; E and F; a synapomorphy O 1; E andF; due to convergent evolution
Currently, two of the extant porpoise species (Y and Z) are placed in the genus Tursiops, and a third species (X) is placed in the genus Delphinus. Assuming this classification reflects evolutionary relatedness, which of the following is the most accurate phylogenetic tree? d O C OB OA OD
