Biologists studying living primates in recent years, such as Geladas and Baboons, have noticed that some of these species may still be able to successful reproduce viable and healthy offspring despite great morphological differences. As well as geographics isolation between these species of hundreds of thousands or several million years. These species known as ___ may pose a problem for identifying different species in the fossil record. a. Chronospecies b. Founder species c. Species isolates d. Syngameons

4) Pretend it's a year later, and you have collected more data to make a more detailed phylogeny. You notice that some of these species of birds are sexually dimorphic (males have significantly different plumage than females, generally much brighter!). You also notice that in some of these species both parents feed the offspring, while in others only the female feeds the offspring. You imagine that having bright males near the nest may tend to attract predators to the young. You want to distinguish between two hypotheses to explain the patterns you see: 1) Males not feeding the young is an adaptation to dimorphism 2) If males don’t feed the young in a species, it will allow them to become brightly colored To begin to address this question, map the characters changes in dimorphism and males feeding the young onto each of the trees on the previous page.
