Every mammal except the weird monotremes, i.e. marsupials and the placentalia.
The name is completely random, "wild beast". Are platypuses not "wild beasts"? They have a freaking poison!!
They split up from the rest of the mammals after the monotremes.
Every other mammal has a placenta.
This baby in pouch thing just feels like a pre-placenta stage.
As of 2020, account for about 20% of the known mammal species!!! www.sciencefocus.com/nature/why-are-there-so-many-species-of-bat/ mentions some reasons:
  • they can fly, so they can move out further
  • their eating habits are highly specialized
Since rat and mouse are not scientifically specific names, we'll just use them interchangeably.
When one specific species is implied, we will mean Mus musculus by default.
Exciting... sometimes cruel. But too exciting not to do:

The point of these is that they are good for transfection apparently.
20k genes, 3 billion base pairs. We can handle this!!!
This is really cool. Ciro Santilli would be tempted to participate, but his wife is not a fan, in part due to the loss of privacy of children. Maybe she is right...
Someone should implement a version of that where you can upload your privately sequenced genome and get analytics for free.
This was the first large part of the genome that was sequenced, in 1981: Cambridge Reference Sequence. Presumably they picked it because it is short and does not undergo crossover.
About 16.6 kbp:
TODO: many places say "exactly" 16,569, it seems that variable number tandem repeat are either rare or don't occur!
By Fred Sanger's group.
As mentioned by Craig Venter in 100 Greatest Discoveries by the Discovery Channel (2004-2005), the main outcomes of the project were:
  • it established the ballpark number of human genes
  • showed that human genomes are very similar across individuals.
Important predecessors:
This was one of the first notable country-led large scale sequencing efforts of the world.
