However, the study's other result of merging the yellow anaconda species Eunectes deschauenseei and E. beniensis into E. notaeus was criticized as premature by Böhme, whose own study upheld E. beniensis as distinct two years earlier. [5] [3] Two reviews published in the month following the discovery criticized the original publication.
A video shared online shows the scale of these 20-foot-long (6.1-meter-long) reptiles as one of the researchers, Dutch biologist Freek Vonk, swims alongside a giant 200-kilo (441-pound) specimen.
A new study suggests human life expectancy is plateauing. In 2022, life expectancy in the US was 77.5 years, but values vary across states. Hawaii has the longest life expectancy, while ...
In England in the 13th–19th centuries with life expectancy at birth rising from perhaps 25 years to over 40, expectation of life at age 30 has been estimated at 20–30 years, [166] giving an average age at death of about 50–60 for those (a minority at the start of the period but two-thirds at its end) surviving beyond their twenties.
This is especially true for Healthy life expectancy, the definition of which criteria may change over time, even within a country. For example, Canada is a country with a fairly high overall life expectancy at 81.63 years; however, this number decreases to 75.5 years for Indigenous people in the country. [4]
Life expectancy at birth was 78.4 years for the total U.S. population in 2023, according to the report released Thursday, an increase of nearly a full year from 77.5 years in 2022. The report ...
