Answer:

biogeography Question 2: Undeveloped or unused features. They are remnants of organs or structures found in an early ancestor that no longer serves as a useful function or may now serve a different function. An examples is the wings of ostriches

Answer:

vestigial structures Question 3: the measure of the ability to survive and produce more offspring relative to other members of the population is called....

Answer:

fitnes

Question 4: evidence of evolution comes from...

Answer:

fossil record, geographic distribution of living species, similarities in embryology homologous body structures,dna and protein similarities/differences, and vestigial traits Question 5: events such as volcanoes, floods, and earthquakes are the basis of...

Answer:

catastrophism Question 6: darwin thought that earth must be much older than scientists previously thought.true or false?

Answer:

true Question 7: discovered extinction and proposed catastrophes to explain mass extinctions.Thought that catastrophes were regional and organisms from other areas migrate into bad areas and repopulate it

Answer:

cuvier

Question 8: a trace of an organism that existed in the past is called...

Answer:

fossils

Question 9: what is incorrect about lamarcks theory of how organisms evolve?

Answer:

he did not explain how traits were passed on to offspring Question 10: the study of fossils can help us to understand how evolution occurs. true or false?

Answer:

true Question 11: humans change a species by breeding it for certain traits. Humans determine which traits are favorable and then breed the individuals that show those traits. Humans are the selective agent.

Answer:

artificial structure

Question 12: individuals have inherited beneficial adaptations that show differential success.They tend to produce more offspring on average than other individuals.

Answer:

natural selection

Question 13: why must selected traits be heritable?

Answer:

if a selected trait is not heritable, it cannot be passed down to the next generation Question 14: Natural selection will in result in species with adaptations that are well suited for survival and reproduction in an environment. More individuals will have the trait in every following generation, as long as the environment is still well suited it.

Answer:

descent with modification` Question 15: Features that are similar in STRUCTURE but appear in different organisms and have different functions. Help to show evidence from different species and show a common

descent. Ex: wing of a bat and human hand

Answer:

homologous structure Question 16: to be considered members of the same species organisms must be able to...

Answer:

reproduce together and have fertile offspring Question 17: More complex forms of life evolved from less complex forms. Proposed evolution by natural selection and descent with modification. charles poetic grandfather.

Answer:

Darwin Question 18: vertebrate embryos repeat the major evolutionary features of ancestral embryos during development.

Answer:

embryology

Question 19: what is variation among members of different species called?

Answer:

interspecific variation Question 20: the more related two organisms are, the more similar their dna will be

Answer:

dna sequence analysis Question 21: darwins discovery of marine organisms high in the mountains led him to think that ancient people had carried sea animals from the seaside up into the mountains. True or False?

Answer:

false Question 22: Earth is much older than previously thought. Wrote natural history in 1749

Answer:

Buffon Question 23: ... is the process of biological change by which descendants come to differ from their ancestors.

Answer:

evolution Question 24: the environment is the selective agent in natural or artificial selection?

Answer:

natural Question 25: the basis of molecular fingerprinting, which compares proteins among cell types

Answer:

protein comparisons Question 26: in natural selection what must be true of the traits that are passed down through generations?

Answer:

the trait musts be one that gives an advantage to certain individuals
