D.They provided more evidence for human evolution.答案(1)推理判断题。根据第一段Humans evolved (进化) from apes.This is what we learned in biology class.But what came before apes?Chinese scientists have discovered fossils that could enrich the evolutionary story of how human...
Whether the fossils are of humans or dinosaurs, they can teach scientists much about species and cultures that existed in the past. Scientists use fossils to make educated guesses about the evolution of different species, and what the climate was like in eras long past. Scientists also use foss...
species of sea cow on Santa Rosa Island. The fossils from that excavation also include mollusks and crabs that give researchers clues to what the environment was like millions of years ago and how the Santa Rosa sea cow fits into the story of sirenian evolution as they spread around the ...
Pterodactyloids emerged in the Middle Jurassic and persisted to the very end of the Late Cretaceous, and fossils show that they did an awful lot more in their evolution than did non-pterodactyloid pterosaurs. Several lineages evolved giant size, and bizarrely specialised skulls and dentitions ...
Last year, researchers led byOxford’s Greger Larsonargued that DNA from a 5,000-year-old Irish dog fossil showed signs thatthis complex evolution happened not once, but twice: once in Europe, and once in Asia. The dogs domesticated in Asia later replaced some of the early European ...
)”以及尾句“By comparing fossils from different time periods, we can track the evolution of a species, see how it adapted to changes in its environment, and understand more about the climate and environment where the fossils were buried.(通过比较来自不同时期的化石,我们可以追踪一个物种的进化,...
but the evolution post-extinction was selective for the things that fell into this group that originated after the boundary," Sclafani said. "Our research indicates that this coincides with a massive reduction in morphological form after theextinction event. In evolutionary biology we call that a ...
Girvanellais one of the common genera of cyanobacteria that plays a monumental role in the evolution of life on Earth and the formation of microbialites. Based on a detailed search in the literature ofGirvanellafossils, we have compiled a global database ofGirvanellafossils and revealed the evol...
