increasing since at least 3.5 billion years ago, the background extinction rate must be smaller than the rate of speciation [3]" I read the (ancient) citation...

said here that Holocene extinctions were not over a short timescale compared to the mass extinction events. Many extinctions over a period of 10s to a...

The extinction event multiplied background extinction rates, and therefore caused most damage to taxa that had a high background extinction rate (by implication...

moved to "Overview") Extinction and humankind (background rate vs. modern rate; maybe mention that we're in the sixth great extinction) We should be able...

21 October 2012 (UTC) From the marine extinction graph in the article, an the background rate of extinction rose c.400Ma, about the time of the evolution...

contributed to, the extinction. However, paleontologists remained skeptical, as their reading of the fossil record suggested that the mass extinctions did not take...

discovery. Of these, 7 are small rodents [1]. Compared to a background global extinction rate of roughly 2 mammal species per millenia, this is quite high...

boundary with few extinctions, and radiation from those Maastrichtian clades may of occurred well past the boundary. Rates of extinction and radiation then...

calculations suggest that the current extinction rate of amphibians could be 211 times the background amphibian extinction rate. If current estimates of amphibian...

Perhaps include the formula which links absolute and apparent magnitude and extinction. m λ − M λ = 5 log d − 5 + A λ {\displaystyle m_{\lambda }-M_{\lambda...

2022 (UTC) I removed the statement that "a very small birth rate can result in the extinction of a people". While that is true, it is also intuitively obvious...

In the "Extinctions by severity" section the table contains the use of '~' for some values. This means the numbers aren't properly sorted. Some columns...

namely the end-Guadalupian extinction/Emeishan flood basalts, the end-Permian extinction/Siberian Traps, the end-Triassic extinction/central Atlantic volcanism...

definition of what "gradual extinction" means, but Extinction#Causes does say (with my emphasis added here) "Extinction of a species may come suddenly...

then discuss the reasons for extinction? Putting the reasons for extinction first leaves the reader with no background as to what has become extinct...

explanation for the extinction of megafauna not just in the Americas, but also in Eurasia. Especially because of clear differences in extinction rates between the...

drove many other species extinct; so explaining the higher background-rate of (marine) extinction after 400Ma. A hundred million years later, the evolution...

value in addition to these as it is more descriptive, and details the extinction theories as a whole. It needs work, but it can be improved and expanded...

deleterious than beneficial, and so the "natural" (background) mutations will lead to extinction of fully genetically isolated small groups. I'd like...
