passive trend (character state vs. time) - ✔✔the maximum and average

have increased over time, but the minimum value has stayed the same


did humans evolve from chimps? - ✔✔no, both humans and chimpanzees

evolved from the same early bipedal hominins


extended phenotypes are... - ✔✔phenotypes that extend outside of the

body such as creating structures, manipulating behavior of hosts, etc.


the flu is an example of a virus that spreads through... - ✔✔horizontal

transmission


Imagine a phylogenetic tree in which several of the terminal taxa (i.e. the

taxa at the very end of branches) share one state of a character, while the

other taxa have another state (e.g. several have green eyes, and the others

, have red eyes). Those with green eyes are not closely related to each other.

Based on what we know about the evolution of traits, what is the most

likely explanation for this pattern? - ✔✔The ancestor all of these taxa share

had red eyes, and several lineages developed green eyes. This is similar to

what we see in the phylogenetic tree of birds, alligators, and lizards. Birds

and alligators are more related than lizards even though lizards and

alligators look more similar. Because the green-eyed individuals are not

closely related they likely developed these traits independently


What does the following figure illustrate? (Each dot represents a pair of

Drosophila species) - ✔✔The strength of prezygotic isolation increases

more rapidly between sympatric pairs of species than it does between

allopatric pairs, most of the sympatric species (red dots) have a higher

strength of prezygotic isolation than similarly-aged allopatric populations

(blue).


Though, with time, allopatric species also develop strong prezygotic

barriers (as shown by the high blue dots on the right of the graph).
