Compare and contrast the multiregional and replacement models for human origins in the table below. If you are struggling with this, see the PowerPoint on the origins and dispersal of modern humans and review the tutorial: https://www2.palomar.edu/anthro/homo2/mod_homo_4.htm Multiregional Model Replacement Main argument of this model Evidence that supports this model Based on the evidence, which model of human origins is best supported?
Figure 4. This map shows the range of five different bird species in North America based on data collected from 1980 to 1995. For each statement, select TRUE if it is consistent, or FALSE if it is not consistent with the information presented above. If you transplant Bird X east over the mountains and they die, then this species range is likely limited by dispersal. Question 16 options: True False
Think about the pattern of human dispersal. Given what you know about the founder effect, would you expect populations native to South America to be more or less genetically diverse than those native to North America?Explain your reasoning
Which type of event is likely to initiate speciation where a mountain range or land bridge forms? • parapatry • sympatry•dispersal• vicariance
True or false. Dispersal or vicariance may possibly lead to isolation and further to separation of lineage from their ancestral lineage or speciation.
Which of the following scenarios best explains how resource partitioning can lead to adaptive radiation? The lack of competition between individuals leads to better survival and reproduction rates. The utilization of different resources requires different adaptations, selecting for different traits. The lack of competition leads to a more balanced ecosystem, resulting in more offspring. There is no connection between adaptive radiation and the resource partitioning in nature.
All of the following are true of primate dispersal, EXCEPT: It helps prevent inbreeding Most transfers of males occur during the breeding season the philopatric sex is the one that disperses Joining a new group can be difficult and have high costs to the new individual
Which statement about dispersal is false?(A) Dispersal is a common component of the life cycles ofplants and animals.(B) Colonization of devastated areas after floods or volcaniceruptions depends on dispersal.(C) Dispersal occurs only on an evolutionary time scale.(D) The ability to disperse can expand the geographic distribution of a species.
Consider a species that occupies a large, but fixed, number of islands. The distribution of the species across all islands is maintained by a balance between local extinctions and local colonization events. Devise a model for the relationship between the fraction of islands occupied by the species and time. Be clear to outline the assumptions you make and be sure to describe your key predictions. Please provide a model for this relationship and be clear to outline the assumptions you make and be sure to describe your key predictions
What is the main difference between dispersal and vicariance? a. One leads to allopatric speciation, whereas the other leads to sympatric speciation. b. One involves the movement of the organism, whereas the other involves a change in the environment. c. One depends on a genetic mutation occurring, whereas the other does not. d. One involves closely related organisms, whereas the other involves only individuals of the same species.
Is the following statement consistent with the provided data? Answer TRUE if the statement is consistent with the data.Answer FALSE if the statement is not consistent with the data. 1. The evolution of freeze tolerance involves some factors that were not shaped directly by natural selection. 2. Because of their freeze tolerance, wood frogs may colonise more of the remainder of the island of Newfoundland than the leopard frog. 3. The distribution of the wood frog and leopard frog supports character displacement as a plausible hypothesis for why they overlap.
Two species evolve different preferences for which tree to live on. The trees are found in the same forest and thus two species are produced from the same geographic location. This is best described as which of the following? Sympatric speciation Vicariance speciation Dispersal speciation Allopatric speciation
