Question

SCIENTIFIC THINKING By measuring the fossil remains of Homo floresiensis, scientists have estimated its weight to be around 32.5 kg and its brain volume to be roughly 420 cm3. Plot these values on the graph in Figure 19.13A. Which hominin has the most similar relationship of brain volume to body mass? Does this information support the hypothesis that H. floresiensis is a dwarf form of H. erectus, or an alternative hypothesis? Explain.

Accepted Answer

Hello everyone and welcome to today's video. So what is the alternative hypothesis of the origin of the homo homo floresiensis Besides being a dwarf descendant of the homo erectus? Well, this homo floresiensis is what we call the Hobbit. Or like the question states the dwarf descendants of homo erectus. Or there is a certain hypothesis. There is an alternative hypothesis that states that this homo floresiensis is actually not its own species. That is actually part of homo sapiens, which is us and that instead of being their own species, they had a genetic disorder and this genetic disorder caused certain bone defects that cause they're abnormal size. Because of this, this could be the confusion that is going on between them being their own species or them being their home part of the homo sapiens with a genetic disorder. This is the alternative hypothesis that the question is talking about because of this. The correct answer choice is going to be answer choice. C. They are homo sapiens with a genetic disorder that causes this bone defects, making them fairly different in terms of morphological e different to homo seconds.
