Fossils of a dwarf species of human, Homo floresiensis, has been discovered on the Indonesian island of Flores. There has been debate as to who are the immediate ancestors. New fossils have just been discovered and dated at 700,000 years ago. This strongly suggests that their immediate ancestors are
A.
Homo habilis
B.
Homo neanderthalensis
C.
Ardipithecus
D.
Homo sapiens
E.
Homo erectus
The Neanderthal nuclear genome:
A. Shows that Neanderthals inherited their ability to flake stone directly from Homo habilis.
B. Is overwhelmingly similar to the modern human genome.
C. Demonstrates once and for all that Neanderthals had language.
D. Is composed exclusively of mitochondrial DNA.
E. Indicates that most Neanderthal females died young, which explains why Neanderthal populations were so small.
Fossilized remains of prehistoric mastodons show anatomical similarities to modern-day elephants. These similarities provided the first evidence that mastodons were related to modern-day elephants. Which of the following is the BEST additional evidence that mastodons were related to elephants?

B.
Mastodon tissues contained proteins with similar amino acid sequences compared to modern-day elephants.
C.
Mastodon fossils were found in the same area where modern-day elephants live.
D.
Mastodons ate a diet similar to that of modern-day elephants.

- You are reading a scientific paper regarding the relationships of the anatomical and behavioral characteristics of chimpanzees and their implications for early hominid evolution. With the emphasis on anatomical and behavioral characteristics, this implies that the researchers are relying on A. Traditional classifications of chimpanzees and humans B. Nonevolutionary classifications of chimpanzees and humans C. An incorrect classification of human ancestors D. Cladistic classifications of chimpanzees and humansarrow_forwardWhat do the Homo erectus fossils from Sangiran, Java, demonstrate? A. H. erectus spread to Eastern Asia after spreading to Europe. B. H. erectus fossils are older in Asia than in Africa. C. H. erectus inhabited parts of Eastern Asia prior to living in Western Asia. D. H. erectus spread rapidly eastward from Western Asia.arrow_forwardChanges in the traits of the fossils studied are consistent with what is expected to be favored by natural selection, given environmental changes during that time. Thus, from the late Miocene, modern horses evolved to have the following traits, consistent with grassland ecosystems becoming more common, EXCEPT for -- A. Formation of hooves and fused forelimb bones. B. Teeth adapted for browsing rather than grazing.. C. A muscle and tendon system allowing for a springing motion in galloping. D. Larger animals better designed for grazing.arrow_forward

They show that H. erectus evolved in Western Asia and then migrated to Africa. C. They demonstrate that H. erectus migrated to Western Asia shortly after evolving in Africa. D. They show that H. erectus migrated from Europe into Western Asia.arrow_forwardAccording to "Our Earliest Ancestors", why can’t scientists just do DNA analysis on these fossil hominins to determine if they are a separate species and possibly what species they belong to? A.The technology for extracting DNA from fossils hasn't been developed yet. B.Scientists can't perform DNA analysis on fossil hominins because the fossils have been contaminated with modern human DNA over the years, making it impossible to isolate the ancient genetic material. C.The fossils would need to be in a -5 degree Celsius environment to prevent DNA from degrading D.The DNA of fossil hominins is too similar to modern humans, making it difficult to distinguish between them.arrow_forwardDNA sequence data suggest that modern humans last shared a common ancestor with Old World monkeys about 25 million years ago. In contrast, humans last shared a common ancestor with New World monkeys about 40 million years ago. What could be concluded about evolutionary relationships among these groups? A.
