There are more than 8 million species of living things on Earth, but none of them — from 100-foot blue whales to microscopic bacteria — has an advantage over the others in the universal struggle for existence.
In a paper published Jan. 8 in the journal Nature Ecology & Evolution, a trio of scientists from universities in the United States and the United Kingdom describe the dynamic that began with the origin of life on Earth 4 billion years ago. They report that regardless of vastly different body size, location and life history, most plant, animal and microbial species are equally “fit” in the struggle for existence. This is because each transmits approximately the same amount of energy over its lifetime to produce the next generation of its species. Tiếp tục đọc “What species is most fit for life? All have an equal chance, scientists say”
Cantonal Hojancha was once a major cattle ranching region. Most of this area was cleared for pasture only 30 years ago. Now, many of the residents have moved into the service industry, and the pasture land has slowly converted back to forest. Photo by
