How does cladistics help us understand phylogeny? A. Cladistics is based on the shared characters between organisms and their network of evolutionary relationships.
B. Cladistics is based on ranking organisms in evolutionary history and predicting prospective future species.
C. Cladistics is based purely on the shared characters between organisms and their ranking in evolutionary history.

The phylogenetic tree illustrates the relationship between humans and our closest living relatives. the tree was based on biochemical comparisons, including dna and amino acid sequences. according to the biomolecular data, we could infer that a) the four organisms do not have a common ancestor. b) humans are more closely related to chimps than any other apes. c) chimps are more closely related to gorillas than they are to humans. eliminate d) there is no evidence if any relationship between the four branches on the tree.
