Document Summary
A cell with heritable (genetic) code and the cell interacts with the environment, grows, and reproduces. Have cells (boundary that separates organism from environment. Has information that encodes all functions of organism (dna/rna) Has the ability to replication/reproduction: going to be similar to parent but will be different in some aspects. Descent with modification: adapt to changes in environment, heritable change. Generation to generation: mutations!!!, enhances survival. Homology: similarity resulting from shared ancestry, ex: homologous structure of mammal limbs suggest descent from a common ancestor (buffon, 1707-1788, evo devo: developmental pathways reveal evolutionary similar (homologies) and mechanisms of change. Fossil record: unconformity: a gap in the rock record. Some of the layers of the rock are missing. Caused by erosion, etc: uplift: something happens that causes the rock to lift up. When the uplift is so intense that it ends up flipping over.
