Biology Paper on Evolution of Birds

Scott Lewis Evolution science lab BIO/101 University of Phoenix Evolution Lab The evolution lab tarradiddle is based the theory of Darwin and Wallace and determining the type of seeds the birds feed on an number rainfall in the island of Galapagos. The birds in this experiment put up on the island and choice is not easy and it is baking hot during the day, freezing cold at night and there isnt much food avail fit. Because of this, the birds have really specialized feeding behaviors. An example of evolution resulting from natural selection was detect among birds living in the Galapagos Island.These birds have varieties that vary in what they eat and their appearance. The peculiarity developed allowed the birds to survive during the dry season or times of drought/low precipitation when little food is available. Then this specialized bill allows the birds to break compete for food resources with other birds and animals. The objective of this experiment is to mark off and det ermine what happen when the parameters are changed over time between the Darwin and Wallace report. The setoff experiment is meant to study the influence of beak sizing on the birds tribe numbers.Deep breaks are suited to crack hard seeds, and shallow beaks are better suited for cracking soft seeds. To test out the hypothesis, I was able to change the beak size of it of Darwin to 17. 0mm and let Wallace Island at 12. 0mm. By doing so, the average out beak size rose over time whereas it fluctuates for Wallace. The postponement size was changed from 10 eggs to 30 eggs for Darwin and left at 10 eggs for Wallace as well as population of 600 and 200 respectively. I also wondered about the changes of bird beaks from island to island.When I changed the cm on the beak, I was able to conclude that these numbers help them adapt to the island and make them to a greater extent fit to survival on available food. The material that was used to get to this hypothesis was accessed through the Evolution Lab on the student website. I was able to change the clutch size as well as the beak because I felt that those where the most important aspects of these experiment. The determine drive for this according to the Darwin and Wallace, is the difference in temperature between summer and winter and the associated consequences for the career of the birds.The different approach that I used for the clutch size was cogitate to biological characteristics, such as the body weight or environmental factors such as climate. I was able to input the two sizes into the development to come up with the results as far as how the population grows with separately size. ================ Input Parameters ================ Parameter DARWIN WALLACE &8212&8212&8212&8212&8212&8212&8212&8212&8212&8212&8212&8212&8212&8212- Initial Beak Size 17. 0 mm 12. 0 mm Heritability 0. 7 0. 7 Variance 2. 0 2. 0 Clutch Size 30. 0 eggs 10. 0 eggsPrecipitation 27. 0 cm 27. 0 cm pull downulation 600. 0 birds 200. 0 birds Island Size 1. 0 km 1. 0 km ==================== Experimental Results ==================== Year Dar Beak Dar Pop Wal Beak Wal Pop &8212&8212&8212&8212&8212&8212&8212&8212-+&8212&8212&8212&8212&8212&8212- 1997 17. 08 600 12. 05 200 1998 17. 08 2142 12. 11 273 1999 17. 2 833 12. 16 401 2000 17. 35 2127 12. 27 447 2001 17. 46 866 12. 37 610 2002 17. 69 1875 12. 47 651 2003 17. 89 1096 12. 7 650 2004 18. 0 1924 12. 49 746 2005 18. 08 1149 12. 65 791 2006 18. 11 1727 12. 84 803 2007 18. 2 1280 13. 02 788 2008 18. 27 1885 13. 25 742 2009 18. 43 1100 13. 32 774 2010 18. 64 1999 13. 33 726 2011 18. 72 1097 13. 48 734 2012 18. 72 1974 13. 63 767 2013 18. 85 1063 13. 59 883 2014 18. 95 1960 13. 69 872 2015 18. 98 1225 13. 82 816 2016 19. 1 2039 13. 96 806 017 19. 16 1035 14. 11 815 2018 19. 27 2030 14. 16 805 2019 19. 31 1042 14. 34 859 2020 19. 37 2020 14. 47 803 2021 19. 41 1149 14. 59 908 2022 19. 46 2010 14. 69 1003 2023 19. 54 1108 14. 9 960 2024 19. 54 2090 15. 09 984 2025 19. 65 1000 15. 31 956 2026 19. 77 2150 15. 37 1049 2027 19. 84 1022 15. 41 950 2028 19. 94 2141 15. 56 974 2029 20. 03 1028 15. 67 961 030 20. 07 2196 15. 9 1024 2031 20. 1 924 16. 08 1090 2032 20. 15 2230 16. 12 989 2033 20. 11 897 16. 23 1051 2034 20. 13 2257 16. 33 1062 2035 20. 21 877 16. 5 1052 2036 20. 24 2286 16. 59 1052 2037 20. 23 865 16. 72 1094 2038 20. 29 2236 16. 83 1097 2039 20. 34 964 16. 97 1145 2040 20. 37 2261 17. 07 1133 2041 20. 48 916 17. 2 1133 2042 20. 52 2251 17. 5 1081 2043 20. 57 958 17. 37 1052 2044 20. 61 2331 17. 5 1095 2045 20. 66 847 17. 64 1082 2046 20. 74 2362 17. 78 1139 2047 20. 85 861 17. 9 1060 2048 20. 88 2518 17. 91 1097 2049 20. 82 703 18. 04 1160 2050 20. 77 2250 18. 16 1238 2051 20. 73 964 18. 3 1220 2052 20. 82 2231 18. 37 1211 2053 20. 92 930 18. 55 1135 2054 20. 96 2302 18. 72 1271 2055 21. 913 18. 85 1284 2056 21. 2 2254 18. 87 1189 2057 21. 28 902 18. 96 1224 2058 21. 29 2392 1 9. 09 1210 2059 21. 28 760 19. 23 1282 2060 21. 28 2463 19. 34 1150 2061 21. 29 735 19. 38 1196 2062 21. 38 2416 19. 39 1265 2063 21. 52 780 19. 47 1299 2064 21. 5 2431 19. 49 1268 2065 21. 51 824 19. 5 1348 2066 21. 53 2457 19. 55 1249 2067 21. 65 758 19. 62 1312 068 21. 73 2583 19. 65 1216 2069 21. 71 672 19. 85 1184 2070 21. 75 2334 19. 85 1291 2071 21. 66 870 19. 97 1248 2072 21. 68 2375 20. 06 1168 2073 21. 73 869 20. 12 1319 2074 21. 77 2302 20. 14 1316 2075 21. 77 894 20. 24 1230 2076 21. 74 2400 20. 32 1313 2077 21. 77 885 20. 4 1328 2078 21. 76 2316 20. 39 1297 2079 21. 78 911 20. 41 1343 2080 21. 78 2410 20. 5 1339 2081 21. 83 776 20. 44 1299 2082 21. 81 2550 20. 49 1286 2083 21. 8 712 20. 6 1303 2084 21. 88 2356 20. 69 1234 2085 21. 88 927 20. 75 1328 2086 21. 87 2318 20. 65 1347 2087 21. 87 856 20. 66 1405 2088 21. 89 2396 20. 64 1296 2089 21. 9 875 20. 7 1327 2090 21. 93 2161 20. 7 1341 2091 22. 0 997 20. 74 1405 2092 22. 04 2458 20. 69 1328 2093 22. 7 781 20. 79 1246 2094 22. 09 2350 20. 81 1344 2095 22. 24 854 20. 83 1272 2096 22. 36 2432 20. 88 1293 2088 21. 98 2146 20. 6 1312 2089 22. 07 1051 20. 69 1368 2090 22. 14 2286 20. 71 1260 2091 22. 19 880 20. 83 1323 2092 22. 2 2386 20. 87 1316 2093 22. 24 869 20. 99 1336 2094 22. 33 2388 20. 96 1420 2095 22. 46 839 20. 97 1355 2096 22. 52 2362 20. 95 1389In conclusion, the hypothesis was accepted in the fact the environmental factors plays a huge role in the survival of the birds. The clutch size is very important in determining whether the population of the birds goes extinct on either island. Clutch size is the number of eggs that a distaff bird lays in her nest and in these experiment, birds mate for life and live for one year and each female produces only one clutch of eggs per year.
