Date Hierarchy. Sometimes when I create a visualization in Power BI desktop with date and sales data, it automatical sets it up with the date hierarchy. I had one visualization set up this way and then added a new data base that had dates in it. I used the date to manage the relationships.
There's recent evidence that Bat's might be related to primates. bats, believe it or not, are mammals that have the same background as us humans. we share a distinct appendage pattern with 5 phalanges. as humans, the bats are related to whales, primates, mice, cats, dogs, etc.... if ur looking for a close relation, u wont find one, because the bat is a very unique evolutionary development.
The vampire bat lineage diverged from its family 26 million years ago. The hairy-legged vampire bat likely diverged from the other two species of vampire bats 21.7 million years ago. Because the hairy-legged vampire bat feeds on bird blood and it is the ancestral vampire bat, it is likely that all vampire bats initially fed on bird blood.
