11. hints about where people’s ancestors settled in the diaspora: Scientists can even narrow down the time period when different groups likely split up and headed in different directions. Earlier in this book, we talked about how evolutionary biologists tracking the origins of Homo sapiens can trace the divergence of two species by looking at DNA shared between them and assuming a fixed rate of mutation, or change over time. The divergence of two or more haplotypes can be traced the same way. Syrian Jews and Eastern European Jews, for example, share many long strands of DNA. But in the centuries since those two groups split apart, those strands have accumulated a lot of random mutations. Assuming a fixed rate of mutation over time, scientists like Ostrer can estimate that the two groups likely split up roughly 2,500 years ago. And, by looking at the geographical distribution of haplotypes over Europe, some scientists have even started to track migration paths. See W. Y. Yang, J. Novembre, E. Eskin, and E. Halperin, “A Model-Based Approach for Analysis of Spatial Structure in Genetic Data,” Nature Genetics 44 (2012): 725–31.

Today it’s fairly widely accepted and is backed by genetic evidence. See, for example, Geoffrey I. McFadden and Giel G. van Dooren, “Evolution: Red Algal Genome Affirms a Common Origin of All Plastids,” Current Biology 14 (July 13, 2004): R514–16.

Full text available via the Internet Archive at http://archive.org/details/marinemammalsofn00scam.
2. Their brains “sleep”: Most scientists believe that gray whales, like other cetaceans, experience “unihemispheric slow wave sleep,” where only one hemisphere of the brain “sleeps” at a time. Whales also experience little to no REM sleep. See, for example, Oleg I. Lyamin, Paul R. Manger, Sam H. Ridgway, Lev M. Mukhametov, and Jerome M. Siegel, “Cetacean Sleep: An Unusual Form of Mammalian Sleep,” Neuroscience & Biobehavioral Reviews 32 (October 2008): 1451–84.

7. A large group of grays lived in the Atlantic for thousands of years: Scott Noakes, “Georgia’s Pleistocene Atlantic Gray Whales,” Gray’s Reef National Marine Sanctuary, http://graysreef.noaa.gov/science/research/gray_whale/welcome.html.
8. 20,000–30,000 individuals: This number is a point of some debate, as populations change every year, and the only way we can count them is by observing how many different individuals pass by observation stations along the Pacific Coast. The number that scientists seem to agree on most is 22,000 individuals, based on average numbers from data collected over the past two decades. The population is growing by over 2 percent every year, and in 2012 over 200 babies were born. I’m basing my numbers on two sources: S. Elizabeth Alter, Eric Rynes, and Stephen Palumbi, “DNA Evidence for Historic Population Size and Past Ecosystem Impacts of Gray Whales,” PNAS 104 (September 18, 2007): 15162–67, and the annual population est
imate reports issued by NOAA, which collects data from several observation stations along the coast from Alaska to Mexico (http://www.nmfs.noaa.gov/pr/sars/).
9. Korean-Okhotsk grays: O. Yu. Tyurneva, Yu. M. Yakovlev, V. V. Vertyankin, and N. I. Selin, “The Peculiarities of Foraging Migrations of the Korean-Okhotsk Gray Whale (Eschrichtius robustus) Population in Russian Waters of the Far Eastern Seas,” Russian Journal of Marine Biology 36 (March 2010): 117–24.
10. in 1949 the newly formed International Whaling Commission: The IWC was established in 1946, and included several member states such as the United States, Japan, and the then Soviet Union. You can see a record of every annual meeting online (http://www.iwcoffice.org/meetings/historical.htm). What’s interesting about this and other early conservation groups is that it combined the interests of environmentalism with commercial interests. It’s also worth noting that some Inuit groups are still permitted to hunt a small number of grays every year.
11. Others argue, based on genetic data: Alter et al., “DNA Evidence for Historic Population Size.”
12. Several studies suggest that noise pollution: Many of these studies are collected in Scott D. Kraus and Rosalind M. Rolland, eds., The Urban Whale: North Atlantic Whales at the Crossroads (Boston: Harvard University Press, 2007).

CHAPTER FOURTEEN: THE MUTATING METROPOLIS
1. In the past decade, the number of people on Earth living in cities: The highlights of “World Urbanization Prospects” (last revised April 2012), a U.N. Report on population demographics in cities, gives us this statistic, adding that “urban dwellers will likely account for 86 percent of the population in the more developed regions and for 64 percent of that in the less developed regions.” You can view the U.N.’s World Urbanization Prospects report, and the data that informs it, on the U.N. website at http://esa.un.org/unpd/wup/index.htm.
2. The World Without Us: Alan Weisman, The World Without Us (New York: Thomas Dunne Books, 2007).
3. It would require us to regulate the bodies of billions of women: I am talking here about what it would take to lower the population over the next half century. Many studies have shown that birth rates plummet dramatically in countries where women receive the same educational and economic opportunities as men. It is my fervent hope that over the long term, women’s equality with men around the world will lead to a population size that is better adapted to the Earth’s environment. Until that happens, however, we must accept that our population is growing and prepare for it.
