Study Guide 4 CH. 21 Genomics – the study of whole sets of genes and their interactions. Bioinformatics – is the application of computational methods to the storage and analysis of biological data Linkage Map – maps the location of several thousand genetic markers on each chromosome Physical Map – Expresses the distance between genetic markers‚ usually as the number of base pairs along the DNA Metagenomics – DNA from a group of species (a metagenome) is collected from an environmental

Chapter 25: History of Life on Earth Synthesis of Organic Compounds on Early Earth * The Earth probably formed about 4.6 billion years ago‚ and was bombarded with rocks and other material until about 3.9 billion years ago. * The Earth then cooled‚ allowing for the formation of oceans. Scientists hypothesize the general atmosphere‚ or at least some regions‚ were naturally reducing environments‚ meaning that they added electrons to compounds. * Activation energy provided by lightening

Continental Drift is the principle that the continent landmasses have not remained in fixed positions‚ but have moved around the earth’s surface apparently independently. It is important in evolution because of the effects it has had on evolution and taxonomic diversity‚ brought about by the collision and moving apart of landmasses. The drifting apart of land masses brings about vicariance‚ where organisms are split up by the development of barriers‚ isolating descendent populations which then evolve

Evolution by natural selection is slow but can be observed in certain situations. How to spot evolution in real time: Artificial selection – manipulation by humans such as breeding dogs or growing corn. Repro-rate – rate of reproduction. Stochastic Event: unexpected disaster like a volcano eruption or tornado. (Research geological time) LIVING THINGS: Biology – Study of living things. Living things – all the organisms descended from a single-celled ancestor. * Characteristics:

In his own words he emphasizes the need of dialog between western science and tribal people and says “corrective measures must be taken to eliminate scientific misconceptions about Indians‚ their
