Solved in 2 steps
- The idea of common descent is a conclusion drawn from the study ofThe process by which inherited characteristics of populations change over time is called_______ . Variability among individuals is the result of chance changes called_________ that occur in the hereditary molecule ________.Lamarck’s proposed mechanism for the inheritance of acquired traits was correct. Group of answer choices: True False
- Modern humans crossed a landbridge from Asia into North America during a glacial period about 20,000 years ago and were the first hominins to occupy the region. Group of answer choices True FalseExplain how we know that there are NO races, or biological subspecies, in modern humans. In your answer be sure to compare and contrast scientific concepts of race and socially constructed concepts of race.
