Modern cetaceans, the taxonomic group that includes whales, dolphins, and porpoises, evolved from land mammals. However, it has only been within the past few decades that transitional fossils have been found that have shed light on cetacean hindlimb reduction. DNA data suggest that cetaceans are most closely related to Hippos, which are even-toed ungulates. Other even-toed ungulates include deer, pigs, camels, and cows. Which statement describes most accurately how the early cetacean, Pakicetus, fossil ankle bones shown in the figure supports the hypothesis that cetaceans are closely related to even-toed ungulates?
A. The Pakicetus ankle bone suggests that Pakicetus most likely evolved from pigs.
B. The two humps on the bottom end of the Pakicetus ankle bone is a distinguishing feature shared with other even-toed ungulates.
C. This demonstrates that the early cetaceans had ankles 50 million years ago.
D. The Pakicetus ankle bone is most similar to other mammal ankles, suggesting a relationship between other mammals and cetaceans.

The galapagos island contain 13 species of finches four of the species are seen here it is believed that all of the species had one common ancestor and overtime

Will mark brainliest i only need the ! 1.use ten beads and a centromere of one color to construct the long chromosome. use ten beads and a centromere of a second color to construct the second chromosome in the long pair. make a drawing of the chromosomes in the space below. 2. for the second pair of chromosomes, use only five beads. 3. now model the replication of the chromosomes. make a drawing of your model in the space below. part b: meiosis i during meiosis i, the cell divides into two diploid daughter cells. 4. pair up the chromosomes to form tetrads. use the longer tetrad to model crossing-over. make a drawing of the tetrads in the space below. 5. line up the tetrads across the center of your “cell.” then model what happens to the chromosomes during anaphase i. 6. divide the cell into two daughter cells. use the space below to make a drawing of the result. part c: meiosis ii during meiosis ii, the daughter cells divide again. 7. line up the chromosomes at the center of the first cell, one above the other. separate the chromatids in each chromosome and move them to opposite sides of the cell. 8. repeat step 7 for the second cell. 9. divide each cell into two daughter cells. use the space below to make a drawing of the four haploid cells
