Meiosis is super important in biology class 11 because it explains how sexual reproduction works at the cellular level! Here's why it matters:

• Produces gametes (sperm and egg cells) with half the chromosome number
• Enables genetic diversity through crossing over and independent assortment
• Maintains chromosome number across generations - without meiosis, chromosome numbers would double each generation!
• Explains variation in populations - which is the basis for evolution

Basically, without meiosis, sexual reproduction as we know it wouldn't be possible. It's one of those fundamental processes that makes life diverse and interesting!

According to traditional Hindu cosmology, the four yugas cycle through vast time periods:

• Satya Yuga: 1,728,000 years
• Treta Yuga: 1,296,000 years
• Dwapara Yuga: 864,000 years
• Kali Yuga: 432,000 years

We're currently in Kali Yuga, which began in 3102 BCE. That means approximately 427,000 years remain until its completion. However, different interpretations exist - some scriptures suggest we're actually much further along. The concept is more philosophical than chronological, representing the gradual decline of righteousness in the world. Many spiritual teachers emphasize focusing on personal dharma rather than calculating exact timelines.
