When Neil Armstrong landed on the moon in 1969 he declared it to be a 'giant leap for mankind'. On the 40th anniversary we asked 12 historians to nominate their alternative giant leaps and you can read their responses here.

We'd love to hear your thoughts on this. What do you think of our experts' choices and what would you nominate as great moments of progress for humanity?

how come Rutherford isn't in here? his theories on atomic behavior and radioactivity?

or William Gilbert and his early theories on electromagnetism which has led to today's digital age?

[Hilary Yewdale]

There have been so many important giant leaps contributing to our lives today - another great leap was the development of the printing press in the 15th century. This made the printed word more easily available to those who could read - making it more practical to circulate knowledge, ideas and information. The availability of more written material encouraged greater levels of literacy and this in turn had an impact on the development of modern societies.

How about the Bible?

[hiphophistorian]

the bible took hundreds of years to write - i see a leap more as a sudden breakthrough or moment in time such as the moon landing

[Reginald Dalton]

I'd say the invention of the wheel was pretty pivotal..

It is decidedly an un-leap to interview 11 men and 1 woman for a feature entitled "12 Giant Leaps for Mankind." What were you thinking? Evolution, anyone?

I'm with Kelli. In addition, I get a bit irritated by the trend for listing things like this - OK if it provokes discussion but you can't seriously expect readers to distil human history into 20 events. And in any case, if that's the aim, it makes a nonesense to miss out the bit where Mr Homo Sapiens said to Mrs Homo Sapiens, "Africa's getting a bit crowded. Let's walk over a few landbridges and settle somewhere else."

[cstuart]

I wonder who the first homo sapien was who created a list and what was the list for?

What about: 1. the summoning by emperor Constantine of the Council of Nikaia; 2. discovery of gunpowder by the Chinese; 3. Gutenberg's printing press.
The first moment gave the world the duality of power between religious and secular authority (it reigned over Europe for one thousand years and it still continues nowadays in some parts of the world); the second revolutionised warfare; the third revolutionised culture and learning.
