To discuss the phylogeny of hippopotamuses, we can refer to the evolutionary tree, or phylogenetic diagram, which illustrates the relationships between various species based on their evolutionary history.
1. **Common Ancestry**: The statement that "millions of years ago, the whale did share a common ancestor with the hippopotamus" is supported by molecular and fossil evidence, placing both of these groups closer together on the evolutionary tree than to other mammals like cows. This can be seen on the diagram where both whales and hippos originate from a common node, suggesting they diverged from a shared lineage.
2. **Evidence of Fossils**: The claim that "more whale fossil evidence has been discovered compared to ancestor fossil evidence of the modern hippopotamus" is reflected in the greater number of documented whale species and their evolution that is represented in fossil records, showcasing a clearer lineage in the evolutionary tree.
3. **Divergence from Cows**: The assertion that "the whale does not share a common ancestor with the cow or hippopotamus" is not wholly accurate. Instead, the evidence indicates that while whales and cows do not share a direct common ancestor on the evolutionary tree, they both share a distant common ancestor at a deeper node. The diagrams typically illustrate that while these two groups diverged, they both trace back to an earlier point in time, but their paths have been distinct since then.
4. **Shared Ancestors**: The information that "the whale, cow, and hippopotamus all share a common ancestor below level A and B" indicates that there is an even older ancestor of all three species that existed before the divergence into separate lineages. This ancestor would be positioned at a deeper branching point on the tree.
5. **Recent Common Ancestors**: Finally, the statement that "the hippopotamus shares a more recent common ancestor with the whale than the cow" reinforces the argument presented in the phylogenetic tree that hippos and whales are more closely related than either is to cows. This would be evident in the diagram, showing a more recent branching event for hippos and whales compared to the branch leading to cows.
In summary, through analysis of the evolutionary tree, we can see the relationships and divergences between whales, hippos, and cows, highlighting their evolutionary connections and the concept of common ancestry within deep time. Understanding the placement of shared ancestors and the relative distances of their branches on the tree allows us to infer their evolutionary history more accurately.
