Cell and Embryology Developmental Biology History and Basic Concepts Textbook: Wolpert L, Beddington R, Jessell T, Lawrence P, Meyerowitz E, Smith J. (2007) Principles of Development. 3th ed. London: Oxford university press. Gilbert SF. (2003) Development Biology. 7th ed. Sunderland: Sinaure Associates Inc. 1 2 Development is a fundamental part of biology Developmental Biology deals with complex mechanisms and many layers of “biological information” superimposed one upon another. Recent advances in cell biology, genetics and molecular biology has and will continue to further our understanding of development unlike any time in the past. Embryogenesis (embryo formation) determines the overall body plan. (Fertilized egg embryo body plan organism) O Organogenesis i (organ ( fformation) ti ) determines d t i subsections b ti off the th body (examples: vertebrate limb, Drosophila eye). Many genes, proteins, signal transduction pathways and cell behaviours are common to both processes. 3 4 1 Model organisms in developmental biology Fig. 1.3 Fig. 1.2 Lizard Although people are mostly interested in human development (for egocentric reasons), many aspects of development are conserved in distantly related species species. South African clawtoed FROG Fig. 1.1 Drosophila The major model organisms used to study the principles of development are... – nematode (Caenorhabditis elegans) – fruit fly (Drosophila melanogaster ) – sea urchins – South African claw-toed ...

The Evolution of Morality, philosophy homework help

must be 1.5 pages longPlease read the entirety of the post before biding. Please use proper sources and citations as well. Please try using these source if possible: Evolution of Morality- Douglas Allchin http://philsci-archive.pitt.edu/137/1/DonM-text.ht... http://philsci-archive.pitt.edu/137/1/DonM-text.ht...Lyons, Sherrie. Evolution: The Basics. New York, NY: Routledge, 2011.The Descent of Man Chapter III & IV. Comparison of the Mental Powers of Man and Lower AnimalsThomas Huxley, Darwin's great defender, wrote, "Is it indeed, true, that the Poet, or the Philosopher, or the Artist whose genius is the glory of his age, is degraded from his high estate by the undoubted historical probability, not to say certainty, that he is the direct descendant of some naked and bestial savage... Is mother-love vile because a hen shows it, or fidelity base because dogs possess it?" Read S. Lyons's introduction to Huxley's Evolution and Ethics and listen to the audio file about animal art and The Jealous Lioness, by Paul Meyerheim, c. 1880. Also read Douglas Allchin's article, "The Evolution of Morality." Please start the discussion with your interpretation of the four stages in Darwin's theory of how a moral sense evolved.I'm sure many of you have pets. Do your pets think; do they know right from wrong? Do they show similar emotions to humans? Share some of your pet stories with the class, arguing for a particular position in light of what both Darwin and Huxley wrote. Please remember this assignment is not to just share adorable pet stories, but to explore the question of how animal behavior might provide insight into the evolution of morality.In your posting you might want to consider one or more of these questions: •How does this relate to the four stages in Darwin's theory of how a moral sense evolved?•Do you think evolutionary theory can provide guidelines to developing a moral code? Why or why not?•What is the relationship between instinct and learned behavior? In your responses to classmates, be sure to indicate whether you agree or disagree with their interpretations of pet behavior, and back up your opinions with alternative explanations or corroborative examples. Be sure to relate these examples to your interpretation of Darwin's four stages.

Genetic technology is becoming commonplace in our lives as new advances appear on a frequent basis. One genetic technology that is garnering increased attention is gene therapy and its potential to cure debilitating diseases like cystic fibrosis, hemophilia and even some cancers. But there is also concern that this technology could be misused.What do you think are some of the pros and cons of gene therapy?How do somatic and germ line gene therapy differ?Might there be more ethical concern over one form of gene therapy than the other?See Chapter 9.4 in your textbook for inspiration.Must be original no references per the Professor.
