    Study Notes

    The Industrial Revolution and Climate Change

    • The Industrial Revolution began around 1750, significantly increasing human CO2 emissions.
    • Prior to the revolution, atmospheric CO2 levels were always below 300 ppm.
    • Advances in agriculture enhanced food supply and living standards.
    • New technologies offered cheaper goods and services, largely powered by fossil fuels, especially coal.
    • Burning fossil fuels has led to a dramatic rise in CO2 concentrations since the 1900s.
    • Historical records indicate that increased atmospheric CO2 correlates with rising average temperatures.

    Glacier Recession and Sea Level Rise

    • Glacier National Park in Montana has seen a significant reduction in glacier size, termed glacier recession.
    • In 1850, the park housed around 150 glaciers; by 2010, only 24 remained larger than 25 acres.
    • Grinnell Glacier, one notable glacier, shrank by 40% between 1966 and 2005.
    • Greenland experienced annual ice loss of 150-250 km from 2002 to 2006.
    • The Arctic Sea ice is also thinning, contributing to global sea level rise.
    • Sea levels rise at an average of 1.8 mm per year; between 1993 and 2010, this rate increased to 2.9-3.4 mm per year.
    • Melting glaciers and polar ice caps release significant amounts of previously frozen water into oceans.

    Ecological Impact of Climate Change

    • Temperature and precipitation shifts affect the geographic distribution and life cycles of plants and animals.
    • Darwin's concept of blending inheritance faced skepticism, leading to alternative evolution theories that emphasized mutations.
    • Darwin's evolution theory lost traction by the end of the 19th century due to competing models that did not account for inheritance.

    Natural Selection and Inheritance

    • Natural selection involves phenotypic selection and genetic response; heritable phenotypes influence reproductive success.
    • For evolution by natural selection to occur, phenotypic differences must be heritable.
    • Blending inheritance theory states that offspring are a mix of their parents' characteristics, complicating the acceptance of Darwin's theory.

    Mendelian Genetics

    • Mendel conducted monohybrid crosses, leading to rules of inheritance: each parent contributes one allele per offspring.
    • Results from these crosses demonstrated a 3:1 ratio of phenotypes in offspring.
    • Probability theory applies to Mendel’s results, where event probability is calculated by outcomes over total possibilities.

    Inductive and Deductive Reasoning

    • Inductive reasoning analyzes data to formulate generalizations, commonly used in studying the human brain.
    • Observational shifts in species distributions due to climate change support predictions about ecological impacts.

    Importance of Replication in Science

    • Replication ensures accuracy and reliability in scientific studies, allowing independent verification.
    • Randomized experiments are crucial for establishing causation by minimizing systematic differences between treatment groups.

    Scientific Inquiry and Methodology

    • Science includes diverse methods beyond experimentation, such as observational studies and natural experiments.
    • The scientific method relies on testing ideas against observations and adjusting theories as new evidence arises.
    • A collaborative scientific community fosters accuracy through diverse perspectives and shared discoveries.
    • Scientific thinking is accessible and applicable to everyday life, emphasizing that anyone can engage in scientific investigation.

    Inheritance and Evolutionary Theories

    • Parents passing unique phenotypes is crucial for population evolution; blending inheritance cannot support variation.
    • In Darwin's era, blending inheritance suggested offspring were an intermediate trait between parents, e.g., height or skin color.
    • Blending inheritance implies that over generations, traits would homogenize, akin to mixing black and white paint ultimately becoming gray.
    • The idea was logical at the time as many traits visually blended; Darwin's breeding experiments indicated awareness of this concept.
    • Other models, despite blending inheritance, attempted to explain species diversity through mutation.
    • By the late 19th century, Darwin's natural selection model lost favor, requiring proof of persistent genetic variation for revival.

    Lamarckian Inheritance

    • Jean-Baptiste Lamarck proposed that acquired traits during an organism's lifetime could be inherited, but his ideas faced ridicule.
    • Synapsis refers to the close pairing of homologous chromosomes during meiosis, allowing for crossing over and genetic recombination.

    Mendelian Genetics

    • Gregor Mendel's 1865 experiments with garden peas led to foundational principles of heredity, focusing on seven traits with distinct phenotypes.
    • Mendel demonstrated that crossing purple and white flowered plants produced only purple flowers in the F1 generation, refuting blending inheritance.
    • The disappearance of the white phenotype suggested a more complex inheritance model, indicating dominance among traits.
    • X-linked recessive traits appear more frequently in males due to female carrier status, whereas in birds, sex-linked traits may appear more often in females.

    DNA Replication and Mutations

    • DNA replication ensures genetic material is accurately copied prior to cell division, though mutations can occur through errors such as wrong nucleotide insertion.
    • DNA polymerase corrects most replication errors via proofreading; remaining mistakes may be fixed later through mismatch repair.
    • In prokaryotes, enzymes recognize the template strand via methylation; eukaryotic mechanisms remain less understood.
    • Mutations can create new alleles, with some beneficial and others deleterious, affecting an organism's survival and reproduction chances.
    • Mutation rates evolve according to environmental factors and the balance between variation benefit and repair costs.

    Evolutionary Insights

    • False belief: Natural selection minimizes mutation chance; mutations are essential for genetic diversity.
    • Lamarck's inheritance of acquired characteristics predicted that environmental adaptations, such as giraffe neck stretching, would be passed to offspring—later disproven.
    • James Hutton argued for gradual geological change through small changes over time, conflicting with the catastrophic paradigm, influencing Darwin's thinking.
    • Charles Lyell further popularized Hutton’s ideas, reinforcing Darwin's understanding of an ancient Earth critical for evolutionary concepts.
