#convergent — Public Fediverse posts

Mammals have developed some unusual eating habits over the past 100 million years, but a new study has uncovered the surprising lengths to which some have gone to satisfy one of the more peculiar—a taste for #ants and #termites.

Mammals independently evolved specialized adaptations for exclusively feeding on ants and termites at least 12 times since the #Cenozoic era began, roughly 66 million years ago.

The #convergent #evolution among #mammals toward this dietary strategy—called #myrmecophagy—emerged following the K-Pg #extinction and fall of non-avian dinosaurs, which reshaped ecosystems and set the stage for ant and termite colonies to rapidly expand worldwide.

Over 200 mammal #species are known to eat ants and termites today, yet only about 20 true myrmecophages—such as giant anteaters, aardvarks and pangolins—have evolved traits like long sticky tongues, specialized claws and stomachs, and reduced or missing teeth, to efficiently consume thousands of these insects daily as their sole food source.

Препод:
-- Я скоро вернусь. Никуда не расходимся.

Передние ряды:
`{\displaystyle \sum _{n=1}^{\infty }{\frac {1}{n^{2}}}`

Задние ряды:
`{\displaystyle \sum _{n=1}^{\infty }{\frac {1}{n}}`

Ряд (математика)#Сходимость и сумма ряда — Википедия

https://ru.wikipedia.org/wiki/%D0%A0%D1%8F%D0%B4_(%D0%BC%D0%B0%D1%82%D0%B5%D0%BC%D0%B0%D1%82%D0%B8%D0%BA%D0%B0)#%D0%A1%D1%85%D0%BE%D0%B4%D0%B8%D0%BC%D0%BE%D1%81%D1%82%D1%8C_%D0%B8_%D1%81%D1%83%D0%BC%D0%BC%D0%B0_%D1%80%D1%8F%D0%B4%D0%B0

Ряд - сумма элементов от 1 до бесконечности.

Одна из характеристик рядов — сходимость. Ряды могут сходиться и расходиться.

Если сумма элементов ряда стремится к какому-либо пределу - значит ряд сходится, если нет - расходится.

1/n - гармонический ряд, и он - расходящийся, так как плавно приближается к бесконечности

1/n^2 - ряд обратных квадратов, и он уже сходится, так как стремится к конкретному значению

Соль шутки:
`На приведённом изображении передние ряды сходятся, задние ряды расходятся`

Rosie Gillespie had previously shown that there have been instances of #repeated #phenotypic evolution (sensu #parallel / #convergent evol).

Using 76 new #genomes, we confirmed this using nuclear (left) and mitochondrial (right) data (notice labeling).
