Which of the following is not a known bias in the fossil record? Fossils from well-studied areas are more likely to appear in the fossil record More abundant species are more likely to be found and in the fossil record Mammals preserve better than birds. Shells and skeletons preserve better than soft-bodied animals.
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 well
The name for the monophyletic group of animals that includes all reptiles, mammals, birds, and amphibians is the ----- . This group is characterised by the evolution and shared presence of ----- . However, some members of this group do not possess this feature because of a process called ----- loss. Snakes are famously legless reptiles, but other reptiles have also lost their limbs to varying degrees. Within the family ---- , we see species that have no limbs and some that have only hind limbs. In the genus ---- we can find species that have fully pentadactyl limbs, as well as those with only 3, 2, or 1 --- per foot.
the ring of gyges what extent would darwin argue that a world where everyone had such rings would contribute to the evolutionary development of humans? Why or why not?
Along comes Dr Phil Bell and deep in the mines of Lightning Ridge, finds an amazingly preserved pterosaur that preserves feathers. He hypothesises that this means that feathers must have evolved before the origin of dinosaurs and therefore must have been primitive. Test this hypothesis using phylogenetic framework and provide a brief explanation of your process and whether or not you support Dr Bell's hypothesis.
Evidence for biocultural evolution during the Upper Pleistocene may exist in the form of craniofacial morphological differences between premodern humans and modern humans because, as one interpretation mentioned in your text suggests… Group of answer choices deep concentration on the creation of cave art murals resulted in the selection for more gracile craniofacial morphology in modern humans hunter gatherers used landscape surveying methods to hunt and gather resources, a practice that required long periods of squinting resulting in supraorbital browridge muscle robusticity frequent spiritual rituals focused around chanting practices resulted in enlarged craniofacial muscle attachments basket weaving techniques required the use of the teeth as a clamp to temporarily hold the sinew technological innovations assisting with food processing resulted in anatomically modern humans not needing large teeth and facial muscles to chew and process their foods
Homologous structures are evidence that O That the animals probably share a common ancestor O That all animals probably came from each other O That all animals probably share the exact same DNA O That all the animals are unrlated
What is wrong with this statement: Birds evolved lighter bones to allowed them to fly and take advantage of open niches. All of the choices are true; none are false. It implies that the variation in the anatomy of birds did not come first, but rather the need did. It implies that there is an intent to evolution. It implies that adaptations evolve out of a need.
As we progress through evolutionary time in the animal kingdom, certain trends emerge. Which is NOT a general trend observable in animal evolution? A general trend towards having a true body cavity A general trend towards asexual reproduction A general trend towards increasing tissue and organ development A general trend towards increasing cephalization
what major difference have scientists discovered between today's whales and the fossils of whales' ancient ancestors
The fossil record shows that the ﬁrst mammals evolved 220 million years ago. The supercontinent Pangaea began to break apart 200 million years ago. On which continents would you predict that fossils of the ﬁrst mammals will be found?
Along comes Dr Phil Bell and deep in the mines of Lightning Ridge, finds an amazingly preserved pterosaur that preserves feathers. He hypothesises that this means that feathers must have evolved before the origin of dinosaurs and therefore must have been primitive. How would you go about testing this hypothesis of feather origins?
