- EVOLUTION LINK Charles Darwin once said, It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change. Explain what he meant.arrow_forwardIn 1847, the German biologist Christian Bergmann noted that mammals and birds living at higher latitudes (farther from the equator) are on average larger and bulkier than related species found at lower latitudes.

- Climate change is affecting the chemistry of the world's oceans. In particular, the ocean water is becoming more acidic. For purple sea urchins, this poses problems as their calcium-based exoskeletons may dissolve in acidic conditions. In a certain population of purple sea urchins, some individuals possess a trait that makes their exterior more resistant to acid. If global climate change continues (as predicted) to make ocean water more acidic, how might this population of purple sea urchins evolve in response to this increased acidification? A:Purple sea urchins with a trait of having shorter, more flexible spines would become more common. B:Purple sea urchins with a trait that make their exoskeletons less resistant to dissolving in acidic water would become more common. C:Purple sea urchins with a trait that make their exoskeletons resistant to dissolving in acidic water would become more common. D:Purple sea urchins with a trait of having longer, more rigid spines would become…arrow_forwardMany species of mammals have complex eyes that are capable of sight. The function of sight is a result of the structure of the eye, the nervous system, and the brain. Removing one of these structures from an organism disrupts the function of sight. Therefore, sight would be best described as an example of a(n) .

- Prompt A large, diverse population of reptiles suffered a catastrophic flood that randomly killed 90% of the population. The surviving individuals then reproduced and the total population size rebounded - albeit with significantly reduced diversity in the gene pool. Questions Which micro-evolutionary mechanism occurred? Why?arrow_forwardIn 1798, a stuffed platypus specimen was delivered to the British Museum. Reports that it laid eggs created much confusion. To modem biologists, a platypus is clearly a mammal. It has fur and the females produce milk. Young animals have typical mammalian teeth that are replaced by hardened pads of the bill as the animal matures. Why do you think modem biologists can more easily accept that a mammal can have some reptilelike traits than scientists who were considering this animal in the late 1700s?arrow_forwardEVOLUTION LINK Although most salamanders have four legs, a few species that live in shallow water lack hind limbs and have extremely tiny forelimbs (see photograph). Develop a hypothesis to explain how limbless salamanders came about according to Darwins mechanism of evolution by natural selection. How could you test your hypothesis? The narrow-striped dwarf siren (Pseudobranchus striatus axanthus) is an aquatic salamander that resembles an eel. It is native to Florida.arrow_forward
- Adaptation and Evolution If you were to present that theme, which representative organisms would you use as example and why?arrow_forwardThis spectacular animal is a Lesser Bird of Paradise, Paradisea minor, from the highlands of Papua New Guinea. In the context of various evolutionary phenomena, why is this bird confined to New Guinea and two nearby islands? Why would you not expect to find it in the mountains of Borneo? This spectacular tail presumably attracts predators; why hasn't natural selection acted to reduce it or camouflage it?arrow_forwardQuestion:- Venomous snakes are some of the most awe-inspiring creatures in nature. Explain how venomous snakes could evolve from a non-venomous ancestor, using the tenants of natural selection.arrow_forward
