Go to and take your free 30-second quiz! Thank you #noom for sponsoring today’s video! In order to truly understand differences among animal lifespans, we need to stop thinking about a specific number and start thinking about a distribution. Check out the MinuteLabs interactive here: LEARN MORE ************** To learn more about this topic, start your googling with these keywords: Life Expectancy At Birth: The average number of years a newborn in a particular group could expect to live. Life Expectancy After Babyhood: The average number of years a member of a particular group could expect to live given that they had survived their first year. Maximum Life Expectancy: The age at which the oldest known member of a particular group died. Mortality Rate: The frequency of occurrence of death within a particular group during a particular time period. Life Table: A table that shows the number of individuals within a group that survive from one year to the next until they are all dead. Survivorship Curve: A plot of the data in a particular life table that shows the years on the x-axis and the number or percent of survivors on the y-axis.
