In the article, "Where do we come from?" Dr. Sang-Hee Lee argued that
incomplete lineage sorting is more common than most biologists think. Which
of the following is evidence for this assertion? Select four correct answers.
The discovery that Australopithecines did not make stone tools.
The discovery of a Denisovan-Neanderthal hybrid, indicating two populations that were speciating,
underwent gene flow and produced hybridized fertile offspring.
The discovery of *Australopithecus sediba* with its mosaic of traits, living at the same time as early
*Homo*, increases the likelihood that members of the genus *Homo* interbred with them.
The discovery of Neanderthal DNA and Denisovan DNA within some populations of modern *Homo
sapiens*, indicating we interbred with them and produced hybridized fertile offspring.
The discovery of *Homo naledi* with its human characteristics mixed with more australopith
characteristics, living at the same time as *Homo sapiens*, 300,000-200,000 years ago, increases the
likelihood we or our ancestors interbred with them.
