Giant Tortoise
Here is a picture of a Galapagos Giant Tortoise with a new born. Seventy may seem rather old to be reproducing, but the Galapagos tortoise doesn't reach sexual maturity until it is 25.
Mating can occur at any time during the year, and the female tortoise can produce between two and 16 tennis ball-sized eggs, which she buries in a 1ft deep nest.
They then incubate for around 130 days. Unusually, temperature can effect the gender of the hatchlings. A low nest temperature means they are likely to be male, while a hot, stuffy nest is more likely to produce females.
However, it is impossible to determine the sex of a Galapagos tortoise until it is 15 years old.
Growth will occur slowly over the next 40 years, at which point the tortoises reach full size. Their large shells add to their impressive appearance and act as a shield against predators.
This magnificent armour is actually a bone, and a crucial part of the tortoise skeleton. However, it does slow them down, as they have an average speed of only 0.18mph.
No one knows why the Galapagos reptiles are so large, but it's possible that a lack of predators on the South American islands meant they evolved free from danger.

Giant Tortoise
But Adwaita was the oldest Giant Tortoise. He was a pet of Robert Clive who was a British Soldier who was credited for securing India in the 18th century.
There was a dispute regarding the age of Adwaita. However, now Adwaita's shell has beencarbon dated, determining his age to be around 255. This makes Adwaita one of the oldest creatures of modern times, beating Harriet by 80 years, and Tu'i Malila by 67 years.
Adwaita means 'one and only'

One of the earliest known maps of the world in the Babylonian map of the world.

This is the Nova totius Terrarum Orbis geographica ac hydrographica tabula, a map of the world created by Hendrik Hondius in 1630, and published the following year in the atlas Atlantis Maioris Appendix.
Among its claims to notability is the fact that it was the first dated map published in an atlas, and therefore the first widely available map, to show any part of Australia, the only previous map to do so being Hessel Gerritsz' 1627 Caert van't Landt van d'Eendracht ("Chart of the Land of Eendracht"), which was not widely distributed.
