How have climate change and grassland environments been hypothesized to have affected the rise of bipedality in primates?
At this time global climate changes (glacial conditions) were taking place that turned many formerly forested areas of Africa into savanna or patchy woodland environments.
what are the advantages of bipedality?
•Generally more energetically efficient (over long distances) than quadrupedal methods of locomotion in terrestrial environments.
•Frees hands for other uses.
•Allows for better long-distant vision.
•Upright primates dissipate heat better than quadrupeds.
•Allows for feeding from tall trees.
•Creates the ability to strike a threatening pose.
What are the disadvantages of bipedality?
•Though more energetically efficient in the long run, for short distances bipedal hominins are often slower than their quadruped relatives.
•Terrestrial (grassland) life makes primates more vulnerable to predation.
What is pair bonding?
monogamous (pair-bonded) relationships between males and females and that there is a selective advantage for males participating in this type of relationship.
What is an estrus cycle?
•When they ovulate their genital region becomes swollen and discolored.
•They are generally only sexually receptive during this time.
What might canine reduction have to do with the rise of bipedality?
What traits do hominins feature other than bipedality?
Where did Darwin say the first hominins would likely be found?
Africa was the likely homeland of the first hominins.
What were his reasons for his choosing this location?
He based this view largely on anatomical similarities between modern humans and African Apes.
What is the Great Rift Valley? Where is it located?
•The main region in which very early hominin fossils have been found
•It is an extension of a sea trench, part of which forms the adjacent Red Sea.
