脊椎动物的智力至少演化了两次

人类以智力为傲,人类大脑可以进行数学计算、运用逻辑、探索抽象概念和批判性思考。但人类不能宣称垄断了思考。鸟类就表现出高级认知能力。而且鸟类的大脑非常小,缺乏科学家认为与哺乳动物智力相关的高度组织化结构。研究大脑结构的德国科学家 Onur Güntürkün 称,鸟的脑只有 10 克重,而黑猩猩的脑重 400 克,它们能做几乎一样的事情。最新研究显示,哺乳动物和鸟类没有从共同祖先继承产生智力的神经通路,两者的智力是独立演化的,表明包含哺乳动物和鸟类在内的有脊椎动物的智力至少演化了两次。哺乳动物和鸟类的大脑结构也表现出趋同演化,它们的大脑有着惊人相似的回路。

NEWS: Telegram supports Facetime video calls NOW!

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.

Telegram and Signal Havens for Right-Wing Extremists

Since the violent storming of Capitol Hill and subsequent ban of former U.S. President Donald Trump from Facebook and Twitter, the removal of Parler from Amazon’s servers, and the de-platforming of incendiary right-wing content, messaging services Telegram and Signal have seen a deluge of new users. In January alone, Telegram reported 90 million new accounts. Its founder, Pavel Durov, described this as “the largest digital migration in human history.” Signal reportedly doubled its user base to 40 million people and became the most downloaded app in 70 countries. The two services rely on encryption to protect the privacy of user communication, which has made them popular with protesters seeking to conceal their identities against repressive governments in places like Belarus, Hong Kong, and Iran. But the same encryption technology has also made them a favored communication tool for criminals and terrorist groups, including al Qaeda and the Islamic State.
