Question

1A )Choose the false statement:

A) Genes that are carried by current species will have no impact on the evolutionary pace or direction of future life; hence, regardless of what kinds of changes in biodiversity are brought on by climate change, the potential for new life forms remains infinite.

B) A modern-day extinction, as is occurring today due to climate change, will probably result in a loss of biodiversity rather than a new explosion of diversity as occurred in the distant past.

C) Our appreciation of nature is much richer when viewed through the lens of evolution; this is what Darwin meant when he wrote the following:

“There is grandeur in [this] view of life, with its several powers having been originally breathed into a few forms or into one: and that whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved.”

1B) Which of the following ideas relating to evolution and biodiversity is incorrect:

A) It incorporates an understanding of molecular biology that takes us beyond using the simple repetitive pattern of mutation à natural selection to explain all forms of variation.

B) It is based on the idea that organisms are able to purposefully generate changes in their genomes that yield desirable complexity more quickly than we might predict.

C) Recognizes that dramatic changes can be generated by introducing minor changes in an organism’s pattern of development.

D) Recognizes that our view of biodiversity is very subjective; hence, on a genetic and cellular level, animals are much more alike than they are different.

1C) Which of the following relating to evolution and biodiversity is correct:

A) Darwin’s grand idea succeeds in being able to account for Biodiversity; hence, his understanding of how adaptations arise can be used to explain the Cambrian Explosion.

B) When two animal phyla share a common pattern of early development one can expect that they will always develop into adults that very closely resemble one another.

C) Much of what we perceive as diversity in nature, evolutionary distance, is really based on appearances and does not necessarily represent great genetic difference; this is illustrated by the fact that we share 50% of our genes with fruit flies and 70% of our genes with frogs.
