1- PROCESS OF EVOLUTION (1 question)

Which of the following statements about macroevolution IS correct?

A.Macroevolution takes more time to occur than microevolution.

B.Macroevolution results in changes within species and within populations.

C.Macroevolution most often results in the production of new species not changes within populations.

D.Macroevolution is usually the accumulation of smaller adaptations.

2- Which of the following are core differences between humans and the great apes? (please check all that apply):

A.Humans use language and abstract thought in ways that other primates cannot

B. Humans are obligate bipeds while apes are facultative bipeds.

C. Humans have larger brains indicating deeper thought/intelligence

D. Humans have the abilities to make and use tools

PHYLOGENY (1 question)

3- Cladograms are visualizations designed to _______ while phylograms are visualizations designed to ________.

highlight which groups share ancestry based on shared traits; also highlight the timing and order of appearance of particular taxa.

4- HOMININ EVOLUTION (4 questions)

Which hominin is considered the a probable biped and why hasn’t he/she been incorporated into the hominin lineage?

A. Australopithecus afarensis (Lucy); because she used a form of mixed locomotion

B. Australopithecus africanus (Taung Child); because he was a juvenile skeleton and we can’t yet determine if he walked upright

C. Ardipithecus (Ardi); because she had a divergent toe and big arms, which make her seem more apelike than the Australopiths (first hominins)

D. Homo erectus; because he was the first to travel long distances using a bipedal stance similar to modern humans (“us”)

5-Early descriptions of _________ described this species as "brutish" and "stupid" based on their stooped postures. It was later determined that these skeletons represented _________.

A. Neandertals; older individuals who had lived tough lives

B. Homo neandertalensis; younger individuals who had lived tough lives

C. Homo heidelbergensis; older individuals who had lived tough lives

D. Modern humans; younger individuals who had lived tough lives

Explanation / Answer

Ans1. Macroevolution most often results in the production of new species not changes within populations.

Explanation: macroevolution occur at high level contrast to the microevolution that occur within population.

It involves the splitting of species into new species. Any changes that occur at higher levels, such as the evolution of new families, phyla or genera, are also macroevolution

Ans 2. Humans are obligate bipeds while apes are facultative bipeds.

C. Humans have larger brains indicating deeper thought/intelligence

D. Humans have the abilities to make and use tools

Are true. However great apes also use some language and make gestures to them.
