Superfamily: Hominoidea (Lesser apes, great apes, and humans) Family: Hominidae (Great apes and humans) Subfamily: Homininae (humans and their closest fossil relatives) Genus: Home Species: sapiens Phylogenetic Relationships Closeness of relatedness: how create hypothetical model of evolutionary relationships among living species? Cladogram - Monophyletic group/clade - Sister taxa - Hypothetical common ancestor Primitive vs. derived features Morphocline Fossil and Living Primates What features are shared by all living primates? (handout and class discussion Plesiadapiformes Middle to Late Paleocene How are they similar to ‘primates of modern aspect’, how do they differ? Prosimians Handout and lecture (coming Tuesday) What are derived characteristics unique to prosimians? Adapidae (Middle to Late Eocene) Lemuridae, Lorisidae, Galagidae, Daubentonia Themes from Recitation: Cell Division -steps of mitosis -what are they called? -what happens in each stage? -steps of meiosis -what are they called? -what happens in each stage? -the source of variation: crossing over (prophase I) -what are the differences between mitosis and meiosis? -stage differences -product differences (sex vs body/autosomal cells, hapoid vs diploid, identical or not?, cyclical or not?) -gene linkage, sex linkage DNA and Protein Synthesis

-DNA (deoxyribonucleic acid) -in the nucleus -3 parts: sugar, phosphate unit, nitrogenous base -A+T, G+C (complementary base pairs) -double helix -genes, chromosomes -functions: replication, protein synthesis -replication: semi-conservative process, creates 2 identical daughter strands -RNA (ribonucleic acid) -different sugar from DNA -U instead of T -Proteins -amino acids polypeptide chains proteins -functions: structural & functional -synthesis occurs in ribosomes -nucleus: DNA mRNA (transcription). mRNA ribosome. tRNA brings in complementary amino acids (translation). Amino acids proteins. Population Genetics -describe populations statistically -conditions for successful reproduction -conditions for genetic equilibrium (Hardy-Weinberg equilibrium) -calculating allele and genotype frequencies

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
