What is endosymbiosis?
What is an organism that lives within the body or cells of another organism?
Wallin’s suggestion in 1925 that ______ “‘may be regarded as symbiotic bacteria”’ sparked Margulis’s life’s work.
What is mitochondria?
What was classification at the time prior to Woese’s work based on?
What is Morphology?
What visual representation of evolutionary relationships was redefined as a result of Woese's discoveries?
What is the tree of life?
Before Lynn’s discovery, why did the differences between prokaryotes and eukaryotes appear "as the greatest discontinuity of evolution"?
What is the difficulty of envisioning how prokaryotes gradually accumulated all of the structures and machinery characteristics of eukaryotes?
What are two of the three points Margulis heavily relied on to draw her scientific theory conclusions? (from cytological studies)
1. Both mitochondria and chloroplasts contain specific DNA and RNA
2. Both organelles are self-reproducing structures, and arise from a preexisting organelle
3. Each organelle contains a genetic system that is inherited separately from the nucleus.
