      The mutation rate of biomolecules is calculated and used narrow down the time in prehistory when two or more organisms diverged. (SZ)

    20. staggered isolation

      Staggered suggests that the occurrence or arrangement of events did not happen at the same time. Staggered isolation is the thought of organisms become genetically isolated at different events or moments in time, therefore leading to speciation of these organisms. (DV)

    21. Isthmus of Panama

      Isthmus is a stretch of narrow land that connects two large landmasses and separates two bodies of water.

      The Isthmus of Panama formed 3 million years ago connecting North America and South America, while separating the Pacific Ocean and the Caribbean. (DV)

    22. sister taxa

      Taxa refers to taxonomical groups like species, family, or class. Taxa are used in classifying organisms based on relatedness of characteristics.

      Sister taxa refers to two groups in which the organisms derived from a common ancestral organism, therefore these two groups are very closely related. (DV)

    23. molecular divergence

      Divergence is the differentiation of something (like an organism's genetic information) from its common state.

      Molecular divergence is the differentiation between the nucleotide sequence in DNA or amino acid sequences in proteins of organisms. (DV)

    24. snapping shrimps (Alpheus)

      The snapping shrimp (Alpheus) is a species of shrimp well known for their asymmetrical claws which when closed produce a loud snapping noise. They borrow in the sand and attack their prey by quickly reaching out with their larger claw to capture it. (DV)

    25. divergence

      A process by which a species evolves into two or more descendant or different forms (SZ)

    26. gene flow

      This explains the process of gene transfer. Usually this is observed from shifts in genes between different populations. So lets say a blue bird from one population migrates out of its territory and mates with a brown bird from the new population, the allele frequency shifts. ~J.D.A.

    1. recombinant inbred lines

      Offspring that have different alleles than their parents as a result of genetic recombination (such as crossing over and random assortment of chromosomes which causes each sex cell to be different from the parents' sex cells). These offspring are then crossed with each other so that resulting generations have nearly identical genes.

    2. genotypes

      The genetic makeup of an individual inherited from one's parents. Genotypes are particularly important in determining which variant of an allele or trait that individual has. When the author says that 14 genotypes were sowed, they mean that 14 different combinations of the same genes were planted in the populations. The plants each had their own variety of these genes. This is an important distinction because a genotype does not mean that the plants had different genes. They simply had different varieties of them.

    3. stochastic

      Random processes, events occurring with no apparent relationship or meaning. Stochastic models are necessary for ecological studies because environmental systems are often impacted by random events such as natural catastrophes or human interference. In order to account for this randomness, multiple trials are done in studies to ensure that the results were not simply a result of randomness. The more trials that affirm a result, the less likely it is that result is due to chance.

    4. genetic drift

      The random selection of organisms to survive and reproduce. Unlike other selection devices, genetic drift is completely due to random chance. An example of genetic drift could be something like a volcano erupting and randomly taking out half of the population just due to chance. Genetic drift is typically more pronounced in smaller populations because changes in allele frequencies are more observable when even just a few members of a population are removed. If those members had a unique trait, their removal can be very influential on the traits of that population.

    5. epigenetic

      Factors outside the strand of DNA that impact how the genes are expressed. The most common examples of this are DNA methylation and histone modifications. Both essentially make the DNA harder to access by the enzymes that convert it into proteins. These epigenetic regulators are mostly caused by environmental factors such as nutrition or exposure to certain chemicals. These epigenetic changes are heritable, meaning the modifications can be passed on to offspring.

    1. immunoprecipitation

      a molecular technique that purifies proteins and finds binding partners by using antibodies that can bind specifically to the protein. Can help find protein complexes.

    2. RNA pull-down

      a test used to confirm the presence of a protein species or to identify natural binding partners for the RNA

    3. In silico

      computer run simulations
