1.С появлением фотосинтеза (первыми фотосинтезирующими организмами были сине-зеленые водоросли) в атмосферу стал выделяться кислород.

2.Основное значение полового размножения для эволюции заключается не просто в увеличении количества особей, а в расширении генофонда, в дальнейшем способствующему естественному отбору.

The Edinburgh Festival

The Edinburgh Festival, held in Scotland’s capital every year, is the largest cultural event in the world. Ever since 1947 when it was first introduced, the city has sprung to life each August, offering a wide range of entertainment. In fact, ‘The Edinburgh Festival’ is much more than one festival – it is in fact a group of arts and cultural festivals that take place around the same time each year. As well as the official ‘Edinburgh Festival’, which offers a fine selection of classical and modern theatre, opera, music, dance, visual arts, talks and workshops, there’s ‘The Edinburgh Fringe’, which offers comedy, musicals and children’s shows and The Edinburgh Film Festival and The Edinburgh International Book festival, just to mention a few.

Truly amazing!

With around 1500 different shows each day across 200 different venues, it’s not surprising that a visit to the city of Edinburgh during the Festival has been voted the number one tourist experience in the UK. Hundreds and thousands of visitors visit the city every year, bringing in 200 million. But, you don’t have to spend a fortune when you come. In fact, many events are free to the public. And it’s great to go and just see what’s happening around you. The atmosphere is truly magic – you can watch the street theatre and listen to live music – or enjoy the firework display at the end of the Festival.

All-year-round entertainment

There’s always something to see in Edinburgh – no matter the time of year. For example, The Edinburgh International Film Festival now takes place in late June; The Edinburg International Science Festival is in April and the International Storytelling Festival happens in October/November each year. Many come and visit during the winter and celebrate ‘Hongmanay’ (New Year’s Eve) in the Festival City. There’s nowhere better to celebrate the New Year!

Where to stay

Edinburgh has a great choice of accommodation. There are plenty of world famous hotels in the city centre, or you can choose to stay in a self- catering apartment close by. Wherever you stay and whatever your budget, you are sure of a warm welcome.
