How does continental drift affect living organisms?
How does continental drift affect living organisms? It causes climate change, which puts selective pressure on organisms. It causes changes in habitats, such as when large amounts of shallow marine habitat were lost in the formation of Pangaea. … Organisms may have to adapt, move, or go extinct.
Which is strong evidence supporting the impact hypothesis for the extinction of the dinosaurs See Section 25.4 page 512?

Which organisms are not examples of an adaptive radiation quizlet?
(Adaptive radiation occurs when a single lineage produces many descendant species.) Which organisms are not examples of an adaptive radiation? Mammals and reptiles in the post-dinosaur age. (Mammals and reptiles are not descended from a single lineage.)
Why are species going extinct due to anthropogenic changes?
The current extinction crisis is entirely of our own making. More than a century of habitat destruction, pollution, the spread of invasive species, overharvest from the wild, climate change, population growth and other human activities have pushed nature to the brink.
Did whales evolve from hippos see Section 25.1 page 497?
Did whales evolve from hippos? See Section 25.1 (Page 497) . No, but they both share a recent common ancestor.
What is genetic drift Chapter 24?
a set of organisms with a unique genetic history. What is genetic drift? A change in allele frequencies caused by random events.
Which factor most likely caused animals and plants in India to differ?
Which factor most likely caused animals and plants in India to differ greatly from species in nearby southeast Asia? The species became separated by convergent evolution. Life in India was wiped out by ancient volcanic eruptions. India was a separate continent until 45 million years ago.
How does continental drift explain the uniqueness of Australian fauna?
How does continental drift explain the uniqueness of Australian fauna? The subsequent separation of the southern continents formed an island of marsupials. … Currently, the big island of Hawaii is thought to be over a hot spot, which is why it is the only one of the seven large islands that has active volcanoes.
Which of the following organisms would be most likely to form a fossil?
Organisms with hard parts such as a mineralized shell, like a trilobite or ammonite, are much more likely to become fossilized than animals with only soft parts such as a jellyfish or worms.
How can mass extinction events be distinguished from background extinctions?
Background extinction involves the decline of the reproductive fitness within a species due to changes in its environment. … Mass extinction involves the death of 75% or more of species in a geologically short period of time due to catastrophic events.
What is exceptional about the early animal faunas from the Ediacaran and Cambrian periods See Section 25.3 page 507?
What is exceptional about the early animal faunas from the Ediacaran and Cambrian Periods? See Section 25.3 ( page 507) . Soft-bodied animals are well represented in these faunas. … Ediacaran animals lacked shells, limbs, heads, and feeding appendages.
Is extensive loss of hair observed in humans and whales an example of Homoplasy or homology see Section 25.1 page?
Is extensive loss of hair observed in humans and whales an example of homoplasy or homology? See Section 25.1. This is homoplasy since whales and humans, who are not closely related, evolved this feature separately by convergent evolution.
What is the name of the planet that hit Earth?
Theia
Theia is a hypothesized ancient planet in the early Solar System that, according to the giant-impact hypothesis, collided with the early Earth around 4.5 billion years ago, with some of the resulting ejected debris gathering to form the Moon.
When did the dinosaurs go extinct?
about 65 million years ago
Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.What is the primary reason the Moon cooled quicker than the Earth?
The Moon is smaller than Earth, so the Moon contained less thermal energy in its core to begin with, and a smaller core cools faster than a larger one.
How do lizard species on mainland California compare in diversity to those found on islands See section 25.3 page?
How do lizard species on mainland California compare in diversity to those found on islands? Due to more open ecological opportunities on a given island, greater differences occur between island species. … A mass extinction occurs when at least 60 percent of species are wiped out within 1 million years.
Which of the following statements best explains how adaptive radiation could have led to the diversity of Anolis species found on the Caribbean islands?
Which of the following statements best explains how adaptive radiation could have led to the diversity of Anolis species found on the Caribbean islands? … Over time, this species diverged into many species as groups of lizards adapted to different habitat niches on the islands.
Which of the following is an example of adaptive radiation?
Darwin finches and Australian marsupials are examples of adaptive radiation.
How does climate change affect species diversity?
Climate change can affect species in myriad ways including the expansion, contraction, and “migration” of habitat; increased incidence of disease and invasive species; changes in temperature, precipitation, and other environmental conditions; shifts in food availability; and failure of ecological relationships with …
How does the change in the environment affect the species population in an area?
Some changes may cause a population to increase. If there are more plants than usual in an area, populations of animals that eat that plant may increase. … Sometimes a population will grow too large for the environment to support. Other changes in limiting factors can cause a population to decrease.Why is it important for animals to never go extinct essay?
Ecological importance
Healthy ecosystems depend on plant and animal species as their foundations. When a species becomes endangered, it is a sign that the ecosystem is slowly falling apart. Each species that is lost triggers the loss of other species within its ecosystem.
What is the leading hypothesis on why humans evolved such large brains see Section 32.4 page 663?
What is the leading hypothesis on why humans evolved such large brains? See Section 32.4 (Page 663). They evolved because of competition with apes. They evolved because of spoken language and tool use.

Why do mass extinctions wipe out species more or less randomly? See Section 25.4 (Page 512) . They are caused by exceptionally harsh, short-term conditions.
What two major lineages make up the living Amniota?
Current research distinguishes two major lineages among amniotes: Synapsida (mammals and their extinct close relatives) and Reptilia. The most diverse group of reptiles is Diapsida (turtles, lizards, snakes, tuatara, crocodylians, birds, and many extinct groups).How long does it take new species to form on Earth?
Across a broad range of species, the research found that for a major change to persist and for changes to accumulate, it took about one million years.
How does gene flow affect biodiversity?
Gene flow is an important mechanism for transferring genetic diversity among populations. Migrants change the distribution of genetic diversity among populations, by modifying allele frequencies (the proportion of members carrying a particular variant of a gene).Which factor is the most likely cause that plants and animals in India differ greatly from species in nearby Southeast Asia?
India was a separate continent until forty-five million years ago. Which factor most likely caused animals and plants in India to differ greatly from species in nearby southeast Asia? Animals from the late Precambrian had soft bodies.
Which statement best explains what caused animals and plants in India to differ greatly from species in nearby Southeast Asia?
Which of the following best explains why animals and plants in India differ greatly from species in nearby Southeast Asia? India was a separate continent until 45 million years ago. At what time was most of the landmass of Earth consolidated into one supercontinent?
How has the continental drift of Australia contributed to the unique development of its mammals?
Australia separated from other continents before evolution of Eutherian mammals. Stock of primitive mammals, that survived on the Southern continent after continental drift, later diverged and evolved in marsupials which are found nowhere in the world.
