Core Viewpoint - A recent discovery by a research team from the Chinese Academy of Sciences provides significant evidence supporting Lamarck's theory of evolution, challenging the long-standing dominance of Darwin's natural selection theory [1][5]. Group 1: Evolutionary Theories - Darwin's theory posits that evolution is a long and harsh "lottery," where random genetic mutations create differences that are then selected by the environment, encapsulated in the phrase "survival of the fittest" [3]. - In contrast, Lamarck's theory suggests that organisms can actively change in response to environmental pressures, and these acquired traits can be passed on to future generations [3][5]. Group 2: Key Findings - The research team discovered that rice plants, when moved from warmer southern regions to the colder northeast, developed increased cold resistance, which could be inherited by their offspring [5][7]. - Initially, scientists suspected that genetic mutations were responsible for this cold resistance, but they found that the genes of the rice plants did not change [5][7]. Group 3: Mechanism of Inheritance - The study revealed that southern rice plants possessed inherent cold-resistant genes that were "locked" by specific chemical groups in a warm environment, akin to sealing a genetic capability [7]. - When exposed to cold conditions, the persistent environmental pressure caused the rice plants to "unlock" these genes, allowing them to exhibit cold resistance and pass this trait on to their descendants [7][9]. Group 4: Implications for Evolution - The findings bridge the gap between Darwin's natural selection and Lamarck's acquired inheritance, suggesting that evolution is influenced not only by random genetic variations but also by environmental pressures that can trigger and select epigenetic changes [9].

Core Viewpoint - The "Are You Dead?" app has gained significant popularity, ranking first in the paid app category on the Apple App Store, and has sparked discussions on social media platforms [2][6]. Group 1: App Features and Purpose - The app is designed as a lightweight safety tool for individuals living alone, requiring users to set emergency contacts and check in regularly. If a user fails to check in for consecutive days, the app will automatically notify their emergency contacts via email the next day [3]. - The app interface prominently features a "check-in" button, with reminders indicating that if a user has not checked in for two days, the system will notify their emergency contacts [3][5]. Group 2: User Reception and Feedback - The app has generated mixed reactions from users. Some find it convenient for elderly individuals and young people living alone, while others criticize the check-in process as cumbersome and express concerns over privacy and the app's pricing [6][7]. - Suggestions for improvement include changing the notification method to SMS, optimizing the check-in process, and renaming the app to something more appealing, such as "Are You Alive?" [8]. Group 3: Legal and Competitive Concerns - There are concerns regarding the app's name, which is similar to the well-known platform "Ele.me," potentially leading to issues of unfair competition. Legal experts have pointed this out [10]. - Apple customer service has stated that users dissatisfied with the app's name can provide feedback, which will be communicated to the developers for potential adjustments [10].
