Document Summary
Explain why lactose tolerance persists in a high frequency of europeans. Explain how the sickle-cell mutation causes selection for heterozygotes. Explain how different skin tone/pigment is positively selected for. Look at the dates for the history of life. Background extinction: at a normal rate (~95% of all extinction) Mass extinction: large percentage of species go extinct in a short period of time due to a large scale extinction event. K-t boundary: iridium layers associated with mass extinction events. Mainly due to habitat loss/ increased size of human population: genetics stuff. Transcription factor (tf): protein that regulates transcription of dna (turns. Regulation of gene expression: when whether and how much a gene is. Patches of dna where tfs can bind to regulate gene expression. A combination of tfs will determine what genes are expressed and how: development. Development depends on both genes and environment --> phenotype. Evolutionary development: how evolution shapes the developmental process to.
