The 100 species with longest life-spans recorded and verified [1] This is a list of the longest-living biological organisms: the individual(s) (or in some instances, clones) of a species with the longest natural maximum life spans. For a given species, such a designation may include:
A survivorship curve is a graph showing the number or proportion of individuals surviving to each age for a given species or group (e.g. males or females). Survivorship curves can be constructed for a given cohort (a group of individuals of roughly the same age) based on a life table. There are three generalized types of survivorship curves: [1]
Possible remains of biotic life were found in 4.1 billion-year-old rocks in Western Australia. [26] [27] Probable origin of life. 4000 Ma Formation of a greenstone belt of the Acasta Gneiss of the Slave craton in northwest Canada - the oldest known rock belt. [28] 3900–2500 Ma Cells resembling prokaryotes appear. [29]
They reach sexual maturity in five to eight years. Baboon males leave their birth group, usually before they reach sexual maturity, whereas females are philopatric and stay in the same group their whole lives. Baboons in captivity have been known to live up to 45 years, while in the wild their life expectancy is between 20 and 30 years.
This may be due to the fact that with proper treatment, captivity can provide refuge against diseases, competition with others of the same species and predators. Most notably, animals with shorter lifespans and faster growth rates benefit more from zoos than animals with higher longevities and slow growth rates.
Since crocodile anatomy has changed only slightly over the last 80 million years, current data on modern crocodilians can be used to estimate the bite force of extinct species. An 11-to-12-metre (36–39 ft) Deinosuchus would apply a force of 23,100 lbf (103,000 N), nearly twice that of the latest, higher bite force estimations of Tyrannosaurus ...
The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
The average yearly survival rate of an adult emperor penguin has been measured at 95.1%, with an average life expectancy of 19.9 years. The same researchers estimated that 1% of emperor penguins hatched could feasibly reach an age of 50 years. [21] In contrast, only 19% of chicks survive their first year of life. [22]
