Question

Draw a phylogeny of major populations of modern humans that would reject the out-of-Africa hypothesis.

Accepted Answer

Hi everyone. Let's look at our next problem here. It says given the following illustration, when did homo erectus diverged from homo habilis and were given a little diagram here? Ah There's a simple tree that lists different homo habilis, homo erectus, homo sapiens down at the bottom and then a more complex tree up above. And so let's look up on the tree above. We're looking at homo erectus. So here's homo erectus here and homo habilis or the species we're looking at and we're looking for when homo erectus diverged from homo habilis. And we see this connection here, you see branching off and if we trace that down to our timeline, We see that that that is between 2.0 and 1.5 million years ago. A closer to 2.0. So let's look at our answer choices, see which fits best. He says two million years ago. Well we're not quite at two million, so that's not our answer choice B says one million years ago. Well we're definitely longer ago than that quite a ways past it. So that's not an answer choice C says 1.8 million years ago, while choice D says 1.5 million years ago. Um well, million years ago, we're definitely past that according to our Diagram. So 1.8 million years ago would be the best description based on the diagram were given. So based on that illustration, when did homo erectus diverged from homo habilis choice C 1.8 million years ago. See you in the next video
