The evolving attitudes of Gen X toward evolution

Middle school and high school students displayed a good deal of uncertainty about evolution, with a third having no attitude about evolution and 44% saying that the statement "human beings as we know them developed from earlier species of animals" was probably true or probably false, reflecting a degree of uncertainty about the issue. During the 15 years after high school, 28% of these Generation X young adults concluded that evolution was definitely true, and 27% thought that evolution was definitely false, according to co-author Mark Ackerman, a professor at Michigan Engineering, the U-M School of Information and Michigan Medicine. "These results demonstrate the impact of postsecondary education, initial career experiences, and the polarization of the political system in the United States," Ackerman said.

"The experience of college-level science courses, the completion of baccalaureate or more advanced degrees, and the development of civic scientific literacy were strong predictors of increased acceptance of evolution."

Imagine the possibility of life forms on other planets that don't resemble any on Earth. What might they look like, and why would they be so different? Juan Pérez-Mercader says it may be possible and the answer may be that they developed from a different type of chemistry. For more than 10 years, the senior research fellow in the Department of Earth & Planetary Sciences and the Origins of Life Initiative at Harvard has studied how to produce synthetic living systems—without relying on biochemistry, or the chemistry that has enabled life on Earth. "We have been trying to build a non-biochemical system, which unaided is capable of executing the essential properties common to all natural living systems," Pérez-Mercader explained. The Pérez-Mercader lab's latest study, published last month in Cell Reports Physical Science, even finds such a system engaged in what Charles Darwin called "the struggle for life." The paper features Pérez-Mercader with co-authors Sai Krishna Katla and Chenyu Lin describing how they created two synthetic models (or "species") and observed the ensuing competition between them.
