Document Summary
Key developments: (1) cell theory, (2) the theory of evolution by natural selection. Both of these developments are unified by the concepts of ancestry and descent. Evolutionary relationships among species and among cells can be represented by phylogenetic trees. How does one do biology (ask questions, generate hypotheses and predictions, and conduct experiments to test them) A zygote is also derived from other cells (namely an egg and a sperm cell) In general, cells contain molecular information (dna) that encodes their physical attributes (through some cells loose their dna) Cells have a boundary between them and the environment. Cells have the ability to harness materials and/or energy. A hypothesis is a proposed explanation (a theory also does this, but on a more general level) A prediction is something that can be measured and must be correct id a hypothesis is valid. Tested to see if maggots appeared spontaneously. Had one piece of meat exposed to air.
