Correct, Expert Verified Answers with
A+ Grade Assurance
which statement is false?
Darwin recognized that lineages may go extinct.
Darwin recognized hybridization as an important means of genetic change.
Darwin recognized that not all descendents of an organism's ancestors still
exist.
Darwin thought that evolution might take thousands of generations.
Darwin recognized that rates of evolutionary change may vary among lineages.
ANSW ✔✔ Darwin recognized hybridization as an important means of genetic
change.
Which of the following is not a benefit of Linnaeus's classification system?
It provides biologists with a common set of names for different organisms.
It provides names for species according to an ordered scheme.
It is hierarchal.
It is well suited for describing patterns of relatedness among different taxa.
,It makes use of colloquial (common) species names. ANSW ✔✔ It makes use
of colloquial (common) species names.
Contrast between Lamarck's and Darwin's hypotheses for how characteristics
evolve, shown across two generations ANSW ✔✔ (A) Under Lamarck's
hypothesis, traits change within the lifetime of individuals because of their
needs, illustrated here by giraffes that need longer necks to reach high leaves.
Changes that are acquired during this generation are passed on to the next
generation. (B) Under Darwin's hypothesis, there is variation among individuals
at the start of each generation. Individuals with certain traits (e.g., a longer
neck) have a greater chance of surviving. The variation is inherited, so survivors
pass on their traits to the next generation. Darwin was right, but about 50
years would pass before scientists would understand how the inherited
variations arise.
The Archean and Proterozoic are
Two prokaryoic kingdoms
referred to as Precambrian time.
stromatolites.
mitochondria and chloroplasts derived from bacterial lineages. ANSW ✔✔
referred to as Precambrian time.
The first evidence of life on earth dates to....?
7 billion years
, 5 billion years
3.5 billion years
1.5 billion years
500,000 years ANSW ✔✔ 3.5 billion years
A major event in the history of life was the evolution of multicellularity, which
is a prerequisite for
endosymbiotic bacteria.
an increase in the availability of nitrogen.
large body size and the development of organs.
protein synthesis.
photosynthesis. ANSW ✔✔ large body size and the development of organs.
Which statement about evolutionary radiation is false?
Species arise in a relatively short time.
