根据发表在 Royal Society Open Science 上的一项研究，霸王龙是在北美洲演化，但其直系祖先来自亚洲，在 7000 多万年前跨过连接两大洲的陆桥来到美洲。当时地球正经历一段气候变冷的时期，霸王龙及其近亲可能比其它恐龙更适应较冷的气候，可能是因为它们有羽毛或更温血的生理结构。北美已经发现了数十块霸王龙化石，但亚洲至今没有发现。研究人员的模型显示，霸王龙直系祖先跨过了西伯利亚和阿拉斯加之间的白令海峡。

Cryptoassets enthusiasts use this application for their trade activities, and they may make donations for this cause.If somehow Telegram do run out of money to sustain themselves they will probably introduce some features that will not hinder the rudimentary principle of Telegram but provide users with enhanced and enriched experience. This could be similar to features where characters can be customized in a game which directly do not affect the in-game strategies but add to the experience.
Can I mute a Telegram group?
In recent times, Telegram has gained a lot of popularity because of the controversy over WhatsApp’s new privacy policy. In January 2021, Telegram was the most downloaded app worldwide and crossed 500 million monthly active users. And with so many active users on the app, people might get messages in bulk from a group or a channel that can be a little irritating. So to get rid of the same, you can mute groups, chats, and channels on Telegram just like WhatsApp. You can mute notifications for one hour, eight hours, or two days, or you can disable notifications forever.
