erginhoca.com – YDS Reading Vocabulary Test 4: The Evolution of Mammals What would have happened if an asteroid hadn’t killed the dinosaurs? Perhaps mammals wouldn’t have evolved to become the planet’s dominant group of animals and humans would never have existed. We’re certainly used to the idea that it was only after the dinosaurs became extinct around 66m years ago, that mammals were able to develop and spread around the globe. But new research suggests this picture of Earth’s evolution may not be completely accurate. Work by a team of palaeontologists from the universities of Chicago and Southampton has unveiled a new level of detail of early mammals. It was discovered that the therian mammals (the kind that gave rise to most modern mammals) were actually beginning to diversify between 10m years and 20m years before the Cretaceous mass extinction event that wiped out the dinosaurs. This finding reflects the considerable changes in our understanding of the early evolution of mammals, thanks to exceptional fossils found over the last few years. Previously, most palaeontologists thought that mammal diversity was suppressed by the dominance of dinosaurs. This was largely based on the fact that many of the early mammal fossils that had been found were from small, insect-eating animals with very similar feeding habits and life histories. But with the help of some astounding new fossils, including several from China, it has been shown that mammals at this time were much more diverse than this suggests. 1. dominant group hakim grup never exist asla var olmamak become extinct yok olmak spread around the globe dünyaya yayılmak Earth’s evolution Dünya’nın evrimi completely accurate tamamıyla doğru unveil details detayları ortaya çıkarmak early mammals ilk memeliler begin to diversify çeşitlenmeye başlamak mass extinction kitlesel yokoluş wipe out dinosaurs dinazorları yok etmek considerable change büyük değişiklik reflect changes değişiklikleri yansıtmak exceptional fossils sıra dışı fosiller mammal diversity memeli çeşitliliği supressed bastırılmış insect-eating böcek yiyen similar feeding habits benzer beslenme alışkanlıkları According to the passage, mammals -----. astounding fossils muazzam fosiller a) emerged long before the dinosaurs emerge long before çok daha öncesinde ortaya çıkmak constrained to particular areas belirli bölgelere sıkışmak harsh competition sert rekabet owe the existence varlığını borçlu olmak wipe out dinosaurs dinazorları yok etmek e) may have thriven much earlier than previously thought previously thought önceden düşünülen thrive başarılı olmak What could be the best title for the passage? face challenges zorluklarla yüzleşmek a) the challenges mammals had to face go extinct yok olmak b) why dinosaurs went extinct too quickly origin of mammals memelilerin kökeni c) the new approach on the real origin of mammals new approach yeni yaklaşım flourish gelişmek d) studies on how mammals were able to flourish unexpected disappearance beklenmedik yokoluş b) were constrained to particular areas due to the dominance of dinosaurs c) were in harsh competition with dinosaurs d) owe their existence to the catastrophe that wiped out the dinosaurs 2. e) the unexpected disappearance of dinosaurs Bu kaynak sadece bireysel çalışmalar için düzenlenmiştir.
