As the ice retreated and plants started to grow near a lake, they release pollen(花粉). Some would fall into the lake, sink to the bottom and mix with the sand.By drilling into the lake bottom it is possible to read the record of the plant life around the lake. The fossil record ...
Global surface temperatures reached record levels in 2024 as the impacts of climate change are being felt around the world. All countries, no matter their development status, are affected by climate change. For example, this month has seen floods in Valencia, Spain, claiming more than 200 lives...

### Response: There are a number of ways to reduce air pollution, such as shifting to renewable energy sources, encouraging the use of public transportation, prohibiting the burning of fossil fuels, implementing policies to reduce emissions from industrial sources, and implementing vehicle emissions ...
Because behavior doesn't leave a fossil record, statements regarding the evolution of behavior are inevitably inferential and based largely on comparisons between related groups of livingspecies. Comparative studies of livingspecies, one of the most powerful tools of evolutionary biology, show that spe...
