Relatedness can be determined by comparing the genomes of two species but that is a much more complex analysis than simply we share 50% of our DNA with bananas..
More recent research has propped up Darwin's theory of common descent (also called common ancestry): genome analysis reveals the genetic difference between humans and chimps to be less than 2 percent. In other words, humans and chimps have DNA sequences that are greater than 98 percent similar. While the genetic similarity between human and ape strengthened Darwin's theory, a significant, unexplained discrepancy remained. While great apes all have 48 chromosomes (24 pairs), humans have only 46 (23 pairs).
