Answer:

On the 30th of December which equates to 0.065 billion years ago

Explanation:

The cosmic calendar was made popular by a famous astronomer named Carl Sagan. His aim was to help people to better understand when a particular prehistoric event in the universe occurred when compared to another prehistoric event.

He achieved the aim by chronologically arranging the 13.8 billion years of the universe age into one year. According to such arrangement, the Big Bang occurred on the 1st of January (13.8 billion years ago) while Dinosaurs went into extinction on the  30th of December (0.065 billion years ago).

Following their extinction, the age of primates began on the 31st of December (Just 40 million years ago). You can see that Carl Sagan's visualization puts the beginning of primates (which men evolved from) immediately after the extinction of Dinosaurs and very far away from the Big Bang that signifies the creation of the universe.

Have you ever wondered how you would get from point A to point B without a ride? Companies such as Uber and Lyft both want a role in being your chauffeur. Overall, they probably do not care much about how you get to your destination, as long as you use their company to do it. Now both companies have introduced rentable bikes, scooters, and even skateboards for your personal use. This took place on July 2, 2018. Uber, which is valued at roughly 62 billion dollars, is currently leading the race. This event is taking place in over 40 cities across America. This will have a good impact on the environment, since these scooters and bikes are electric and do not require fuel like cars do. As long as Uber and Lyft respect regulations during this battle, nothing should go wrong. Maybe one day you might rent a bike to the mall, and catch a car to get home- all within your phone.

There are four important categories inside the ABO group: A, B, O, and AB. inside those organizations, there are an additional, eight blood types.

There are four primary blood companies (styles of blood) – A, B, AB and O. Your blood group is determined by the genes you inherit from your parents. every organization can be either RhD wonderful or RhD poor, this means that in total there are 8 blood organizations.

The ABO system: blood group A – has A antigens in the red blood cells with anti-B antibodies in the plasma. blood organization B – has B antigens with anti-A antibodies in the plasma. blood group O – has no antigens, but both anti-A and anti-B antibodies within the plasma. blood group AB – has both A and B antigens.
