Mammals shrink faster than they grow - Technology & Science An international team of scientists, including some from Canada, has discovered that mammals shrink at faster rates than they grow — a finding that sheds light on the conditions that potentially contribute to extinction. Their study, published Monday in the Proceedings of the National Academy of Sciences, shows it took about 24 million generations for a mouse-sized animal to evolve to the size of an elephant, but only 100,000 generations for very large decreases leading to dwarfism to occur. The research is unique because previous work in this area has focused on microevolution — the small changes that occur within a species.

Artificial selection in the lab Artificial selection in the lab For thousands of years, humans have been influencing evolution, through changes we have caused in the environment — and through artificial selection in the domestication of plants and animals. In many cases, scientists have carefully documented evolution through artificial selection in the lab.
