But the world of animals reveals that high fertility and longevity are often mutually exclusive: Particularly animals with shorter lifespans are often very fertile while animals that live longer frequently produce fewer offspring. It seems that organisms with limited resources can be either long-lived or very fertile\u2014but they can&#8217;t be both at the same time. Scientists at the Max Planck Institute for Evolutionary Biology in Pl\u00f6n have now discovered how the trade-off between survival and fertility works. They have found that the average age at reproduction is a measure for the loss of fertility as life expectancy increases.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2019-06-longer-children.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Those who live longer have fewer children<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A long life and lots of children\u2014that was quite a common aspiration until not so long ago.
