Aloy won't get much beyond the nutritional information of these potato monsters. If she tries to recreate their creation, all she will see is them bursting out of the earth and scurrying out. The most she may able to glean is that it appears this is a spontaneous evolution and it may be a result of something in the water.

There will be things underground that she can scan and pull more interesting results from once the log goes up. If you'd like to have her investigate those then swing back around once it goes up!
