Textbook Question
Chapter 51, Problem 10TYU
SCIENCE, TECHNOLOGY, AND SOCIETY Researchers are very interested in studying Identical twins separated at birth and raised apart. So far, the data reveal that such twins frequently have similar personalities, mannerisms, habits, and interests. What general question do you think researchers hope to answer by studying such twins? Why do identical twins make good subjects for this research? What are the potential pitfalls of this research? What abuses might occur if the studies are not evaluated critically? Explain your thinking.

It is a basic idea of human biology, taught in grade schools everywhere: Identical twins come from the same fertilized egg and share identical genetic profiles. But according to new research, though identical twins share very similar genes, identical they are not. The discovery opens a new understanding of why two people who hail from the same embryo can differ in phenotype (physical characteristics), as biologists refer to a person’s physical manifestation.
The new findings appear in the March issue of The American Journal of Human Genetics, in a study conducted by scientists at the University of Alabama at Birmingham and universities in Sweden and the Netherlands. The scientists examined the genes of 10 pairs of monozygotic, or identical, twins, including 9 pairs in which one twin showed signs of dementia or Parkinson’s disease and the other did not.
It has long been known that identical twins develop differences that result from the environment. And in recent years, it has also…
Evolution:
What could lead to different populations of the same species living in different environments?
The concepts of natural selection and evolution are central to how most biologists understand and interpret the world, and yet the theory of evolution is contrary to the beliefs of many religious groups. Why do you think this theory is so important to science and so strongly opposed by others? What evidence would be required to convince opponents of evolution?

However, nursing bees themselves do not reproduce. How could natural selection act upon such behavior? Because this behavior does not directly benefit the nursing bee itself, it is not favored by natural selection. Because this behavior increases the number of surviving offspring that share genes with the nursing bee, it is favored by natural selection. Because this behavior selectively decreases the number of offspring harboring non-similar genes with the nursing bee, it is favored by natural selection. Because this behavior does not increase the number of surviving offspring that are identical in genes with the nursing bee, it is not favored by natural selection.arrow_forwardWhat are the Equality in the Sexes in Human Evolution?
