DNA analysis reignites fierce debate over fate of 9,000-year-old skeleton. Genome sequencing indicates Kennewick Man is Native American, reopening the bitter battle over whether he should be reburied or studied.
How snakes lost a blueprint for making limbs. When researchers inserted the snake DNA into mice, the animals developed truncated limbs, suggesting that a critical stretch of DNA lost its ability to support limb growth during snake evolution. Snakes lost their limbs over 100 million years ago, but scientists have struggled to identify the genetic changes involved.
Ancient rice DNA data provides new view of domestication history. Now, using new data collected samples of ancient, carbonized rice, a team of Japanese and Chinese scientists have successfully determined DNA sequences to make the first comparisons between modern and ancient rice. To do so, they used new techniques to carefully cull chloroplast DNA from ancient rice 900-2,800-years-old, which had been excavated from seven archaeological sites in Japan and Korea. They have new findings…
