Case looks at genetics of Tibetans and Chinese and analyzes prenatal and postnatal mortality.]]> https://www.biologycorner.com/2018/04/02/case-study-how-do-tibetans-survive/feed/ 0 Data Analysis: Funky Juncos https://www.biologycorner.com/2018/03/29/data-analysis-funky-juncos/ https://www.biologycorner.com/2018/03/29/data-analysis-funky-juncos/#respond Thu, 29 Mar 2018 21:04:12 +0000 https://www.biologycorner.com/?p=6394 This data analysis is paired with a short video about how a group of birds split from the main population and evolved in relative isolation near a college campus.   The film is  is 88 minutes long and all of its parts can be viewed at the Juncoproject.com, though for this activity, only one 16 minute chapter is viewed.    The document below contains film questions, data sets, abstract, and a CER (claim, evidence, reasoning) chart.   The google slides can be used to supplement class discussions as students try to make sense of the provided data tables.
