Themost recent common ancestor(MRCA) of all coronaviruses is estimated to have existed as recently as 8000BCE, although some models place the common ancestor as far back as 55 million years or more, implying long term coevolution with bat and avian species.[63]The most recent common ancestor of the alphacoronavirus line has been placed at about 2400 BCE, of the betacoronavirus line at 3300 BCE, of the gammacoronavirus line at 2800 BCE, and of the deltacoronavirus line at about 3000 BCE. Bats and birds, aswarm-bloodedflying vertebrates, are an idealnatural reservoirfor the coronavirus gene pool (withbats the reservoirfor alphacoronaviruses and betacoronavirus – and birds the reservoir for gammacoronaviruses and deltacoronaviruses). The large number and global range of bat and avian species that host viruses has enabled extensive evolution and dissemination of coronaviruses.[64]
This corona is part of our nature Will go back soon or later is not a new disease.
