Looks like Wiki did a small whoopsie. The Canaanites were not indigenous to Canaan. Anthropologists say that the origins of the Canaanites were as follows: a group migrated from the Caucasus Mountains, and intermarried with a Neolithic people that already existed there, and the resulting new culture was the Canaanites.
"It turned out the Greeks were half right: About 50% of the Canaanites' genes came from local farmers who settled the Levant about 10,000 years ago. But the other half was linked to an earlier population identified from skeletons found in Iran, the team reports today in The American Journal of Human Genetics."
"The genes of Canaanite individuals proved to be a mix of local Neolithic people and the Caucasus migrants, who began showing up in the region around the start of the Bronze Age."
A study of ancient DNA traces the surprising heritage of these mysterious Bronze Age people.

If you really are interested in the indigenous people of Canaan, Wikipedia has this good article. Scroll down to the section on the Paleolithic era. Basically, the first time homo sapiens tried to settle the Levant, they were unsuccessful, and overtaken by local Neanderthal culture. That was around 90,000 BCE. A second and successful attempt by homo sapiens out of Africa to settle the Levant came around 50,000 BCE. Anthropologists have labeled this culture the Boker Tachtit. So, the "indigenous people" of the Levant would be the Boker Tachtit, not the Canaanites.
