The statement that is true is:
**Fossils can provide information about when life forms existed.**
Fossils give us insights into the history of life on Earth, including when different organisms existed and how they changed over time. They can also provide some information about relatedness and behaviors, but they do not provide a complete picture of the entire evolutionary process.

Without the specific phylogeny diagram or tree you are referring to, I can't directly identify the relationship between species 4 and the other species.
However, in a typical phylogenetic tree, the species that are most closely related share a more recent common ancestor. If species 4 is positioned closer to one of the other species (1, 3, or 5) than to the others, then that species would be considered its closest relative.
If you're uncertain based on the tree structure, the option "1 or 3 (Can't tell)" would be an appropriate response if both species 1 and 3 are equally close to species 4 in the diagram.
If you provide the structure or key details from the phylogeny, I can give a more precise answer.

The statement that describes a limitation of using the fossil record and comparative anatomy to assemble evolutionary lineages is:
**They can show false relationships between organisms that are not reflected in the DNA.**
While the fossil record and comparative anatomy provide valuable insights into evolutionary relationships, they can sometimes lead to misleading conclusions about how species are related, especially when convergent evolution or other factors complicate the interpretation. Molecular evidence, such as DNA analysis, can often provide a clearer picture of the true relationships between organisms.

The accurate statement about evolution is:
**Living things have adapted and changed over time for specific, discoverable reasons.**
This acknowledges that evolution is a process driven by mechanisms such as natural selection, genetic drift, and mutation, which can lead to adaptations and changes in living organisms over time. The other statements are inaccurate: all living things share a common ancestry, evolution continues to be a field of active research and study, and while DNA provides significant evidence for evolution, there are many other forms of evidence supporting the theory, such as the fossil record and comparative anatomy.

The correct response is:
**This suggests that all of these species share a common ancestor.**
The presence of a gene for insulin hormone in chimpanzees, chickens, cows, and humans indicates that these species have a shared evolutionary history. It suggests that they all descended from a common ancestor that had this gene, which has been preserved and underwent modification in various lineages over time.
