+# Native American Assimilation and Activism Week Two Reflection
+
+> This is the first in a bi-weekly series that I will be publishing for my Native
+American Assimilation and Activism class. Every two weeks we make posts
+sharing what we learned in the class. Unfortunately, due to weather in England I
+was unable to make it back to the United States in time for the first lecture.
+
+One of the key discussions in Monday's lecture/discussion was since time
+immemorial and teaching around that. Time Immemorium is a period before
+human memory, and involved other human species, travel stories, and creation
+stories. Some of the key lessons I learned from that class were:
+
+* Humans branched from some common ancestor that had multiple other human species branch off
+    * We are not evolved from chimps but also have a shared ancestor
+* Many genetic evolutional specializations have to do with environmental adaptation
+    * Some of these adaptations were shared when isolated groups had visitors (Weaving rivers theory)
+    * Also related: Intergenerational Trauma
+
+Oregon and Washington have been leading the country when it comes to
+integrating Native Americans into their school curriculum. This includes
+adding Since Time Immemorium curriculum. These advances have the
+possibility to significantly improve the awareness and appreciation of Native
+American Peoples who have and still live in these lands.
