Darwin: Educators’ Professional Development Program Evaluation Prepared by Ellen Giusti New York area educators were invited to a professional development event at the American museum of Natural History on February 2‚ 2006‚ from 4:00 to 7:00 PM. The purpose of the evening was to acquaint teachers with the Museum’s Darwin exhibition and to offer methods for using it to enhance classroom instruction. The event took place in the Hall of Reptiles and Amphibians and the exhibition in Gallery 3. Darwin

of organisms over time. Darwin was influenced by Lamark and Malthus‚ who were other scientists during his time. Lamar believed that acquired characters are passed on to offspring. For example‚ giraffe necks would change for “adaptation”. Giraffes would be born with longer necks. Malthus believed that populations try to go beyond support capacity. He believed they go through competition and struggle for survival amongst each other. At the Galapagos Islands‚ Charles Darwin believed that species were

mutation and gene flow. Natural selection is a key mechanism of Evolutionary theory and was originally proposed by Darwin. This mechanism is a slow process of evolution by which biological characteristics in a population become more or less prominent depending on an organisms differential reproduction success at adapting to their environment (Darwin‚ 1861). For Example Darwin’s finches (Grant et al‚ 1976) shows how each different finch had passed on an adaptive biological

said that the Galapagos Islands were not islands‚ but only shadows (Danulat‚ 2003). Since this time the islands became a demanded place mostly because the islands served as source of food in long journeys. But‚ it was by the year 1835 when Charles Darwin made his discoveries about the species that were thought before to be immutable to be now part of the “Darwin’s theory of Natural Selection” which says that the species adapt according to their environment‚ that the Islands gained a lot of recognition

Charles Robert Darwin has had the greatest influence on the world by proving the evolution of living things. Charles Darwin had first noticed the similarities of plants and animals when he took a five-year cruise on the H.M.S. Beagle‚ which was available to him through a friend from school. During the cruise Charles Darwin started becoming interested with the similarities between the plants and animals that were similar on different islands with similar climates‚ so he decided to study them more

The population is 200 finches at Darwin Island‚ and 200 finches at Wallace Island. The year is 1997‚ and scientist measured the finch beak size from both Darwin and Wallace Island.

Darwin destroyed the concept of human specialness I would say I disagree quite strongly with the assertion that Darwin destroyed the specialness of humanity. For this relatively brief paper I am going to attempt to refute this claim and try to highlight some of the things that highlight how we have kept the same level of ’specialness ’ that we have always had. There are many people who would say that we humans are the only beings with full consciousness‚ in the words of a great many this would
