Lecture 17 Flashcards
What is allometry?
the study of body scaling
What is the square cube law?
as the side length increases the volume is majorly impacted even if the length only slightly increases
Which three adaptations do teeth have?
mechanical chewing, food capture and sexual selection
What is isometry?
when measurements stay the same
What is growth allometry?
when measurements change throughout the life
what is intraspecific allometry?
same species vary in size eg sex
what is interspecific allometry?
within different species differences
How do behaviours change as size increases?
more likely to stand straight to avoid breakages
What happened to primates in the myocene?
apes declined monkeys increased
R selection
don’t care for young and breed tonnes
K selection
few young but cared for eg apes
how are primates evolved to climb?
can grasp with feet, claws
when is a substrate discontinuous
in arboreal creatures
when is suspensory locomotion better?
in heavier primates so they don’t fall when leaping
features of terrestrial quadruped’s
eg baboons - shorter digits, digitigrade
