- 21. How about these guys?
- 22. Neanderthal man
- 23. What color were their eyes?
- 24. Who knows?
- 25. Who cares?
- 26. How can we find out?
- 27. DNA samples?
- 30. Take out some blood
- 31. Whose blood?
- 32. The blood of a neanderthal man!!
- 33. Get a DNA sample
- 34. Bring back lost people
- 35. No … I don’t want to come back!!
- 36. I don’t like modern humans
- 37. OK … different animals
- 38. Bring these back
- 39. Great idea
- 40. We can do it!
- 41. We have the cloning technology
- 42. Really?
- 43. We really have the cloning technology?
- 44. No, not really!
- 45. Don’t be stupid.
- 46. It’s just a movie!
- 47. But scientists CAN analyze DNA
- 48. That’s kind of clever
- 49. For example?
- 50. Get DNA from bones
- 51. Figure out eye color
- 52. Figure out eye color?
- 53. Yes
- 55. No
- 56. Who is going to study that?!
- 58. Exciting!
- 59. Eye color and DNA
- 60. We can predict eye color!
- 61. Kind of …
- 62. To a certain extent
- 64. Parents’ eyes, children’s eyes
- 65. Two brown eyed parents • 75% chance brown • 19% chance blue • 7% chance green
- 66. One brown one blue • 50% chance brown • 50% chance blue • 0% chance green
- 68. Who needs this?
- 69. We can predict EYE COLOR!!!!
- 71. Actually, some people care
- 75. Forensic science
- 76. Elementary, my dear Watson
- 77. Actually, it’s NOT elementary
- 79. Analysing DNA to solve crimes
- 80. DNA swab test
- 81. Maybe you commit a crime
- 82. We get a sample of your DNA
- 83. You are the criminal
- 84. I am Poirot
- 85. I don’t need DNA
- 86. I am a fictional detective
- 87. How do they do it?
- 89. Chromosome
- 90. Long strand of DNA
- 91. DNA consists of many genes
- 92. Genes carry code
- 93. Eye color, blood type, etc
- 94. Genes are segments of DNA
- 95. Certain genes determine eye color
- 96. • Eight genes for eye color • Two are the strongest predictors • But they ALL have an influence
- 97. Forensic science
- 98. Must be very accurate
- 99. Must be VERY careful
- 100. Modern forensic scientists …
- 101. … use computers
- 102. Computer models of genetic variation
- 103. NOT like this!
- 104. DNA samples
- 105. Eye color data
- 106. From 6,000 people
- 107. Information into the computer
- 108. Great!
- 109. I’m a forensic molecular biologist
- 110. Call me FMB
- 111. Give me your DNA sample!
- 112. Give it to me!!
- 113. OK, here it is!
- 114. Here’s my DNA sample
- 115. OK, I’ve analyzed your DNA sample
- 116. I used my fantastic computer model!
- 117. Now I will predict your eye color!!
- 118. Using my fantastic computer model!
- 119. Why don’t you just look at my eyes?
- 120. Shut up!
- 121. I will use my great computer model
- 122. OK, I’ve finished.
- 123. Your eyes are blue
- 124. No, they are brown
- 125. Never mind. Only 90% accuracy for blue and brown
- 126. Why didn’t you just look at my eyes?
- 127. Shut up! This is forensic science
- 128. 90% accuracy for blue and brown
- 129. 70% for other colors
- 130. The future is bright
- 131. We can predict everything!
- 132. Your hair is red!
- 133. Your designer baby’s hair will be blue

- 136. Should we be able to decide EVERYTHING?
- 137. Even change things about our babies?
- 138. Change a baby’s DNA?
- 139. Should scientists really be involved in this?
- 140. Can we trust scientists?
- 141. Is it natural?
- 142. What if you gave a DNA sample …
- 143. … then three weeks later …
- 144. … the police come to your door …
- 145. … and say, we compared your DNA …
- 146. … with DNA at a murder scene.
- 147. You are a murderer!
- 148. You are a murderer!
- 149. You are a murderer!
- 150. My computer model says so!
