(Phys.org) —Cheng Qin of Sichuan Agricultural University in China and his colleagues have sequenced the genomes of wild and domesticated peppers and found that a large percentage of the pepper genome consists of transposons, ...
We like to think of evolution as a fine-tuning process, one that whittles away genetic redundancies. The only problem is, we are not fine-tuned machines. Our bodies are chock-full of parts that either don't work anymore or ...
