- Which of the following is NOT true about the Homo floresiensis fossil remains? Group of answer choices Were likely afflicted with a severe growth defects May have evolved from ancestors that left Africa before Homo erectus They were recovered in Liang Bua Cave on the island of Flores, east of Java have been affectionately named "the Hobbits" Were contemporary with modern humans 25 kyaEstimate the number of hominin species that have existed in both robust and gracile clades of evolution over the last 6 million years. > 1000 ~ 20 – 30 2: Austropithicus and Homo 1: only Homo sapienMatch the fossil hominin with is most accurate description; not all hominids will be used. Question 8 options: East African hominin that was bipedal while still living in the trees. Heavily-built hominin in Europe who left some genes in the modern day gene pool. First hominin that is found with stone tools. First hominin to be found in both East and South Africa. 1. Australopithecus 2. Sahelanthropus 3. Neandertal 4. Homo erectus 5. Ardipithecus 6. Homo habilis
- If you as a paleoanthropologist are plannin an excavation at a hominin site in East Africa which is dated to about 2 million years old, which fossil hominin species might you expect to find?Which of the following statements about hominins is FALSE? Each hominin species on Earth was directly descended from the species that preceded it Multiple hominin species lived at the same time The genus homo arose about 2.5 million years ago We have now discovered a vast number of hominin fossils, allowing us to trace the evolution of humans fairly wellWhich of the following is not an adaptive pattern of early African hominins? Group of answer choices Speciation was occurring quite frequently. Early hominin species had restricted ranges, thus it is likely they each exploited a small area allowing for rapid genetic diversification through genetic drift and natural selection and speciation. Most of the species appear to have been tied to desert-arid habitats. With the exception of early Homo, there are few evolutionary trends regarding increases in body size or encephalization. All of the early hominins show an ape-like developmental pattern.
- Based on the fossil record, when did hominins first appear in Africa? Group of answer choices ~ 12 kya ~ 6 mya ~ 12 mya ~ 2 mya ~ 6 kyaWhich hominins might be ancestral to us choose one that you find especially interesting (except H. sapiens) and explain how it fits into the picture of the Hominin family?Evolution in Humans 1) explain how fossil evidence is used to reconstruct the hominid history 2) explain how genetic evidence is used to document changes in species and populations over time 3) describe several techniques that paleontologists today use to establish fossil age
- Put the following hominins in order from the oldest to youngest in terms of when they first appear in the fossil record. The Denisovans Ardipithecus kadabbe Paranthropus Australopithecus aforensis Homo erectusCompare and contrast hominin evolution through the years using the following criteria: Species Social and cultural behaviour Anatomy (ex. skull) HabitatYou have discovered a 2.1 million year old fossil with a parabola-shaped tooth row and a brain size of 600ec.
