What type of structure is this:
an evolutionary leftover with no function (ex wisdom teeth)
Vestigial Structures

What is the purpose of a cladogram?
show evolutionary relationships between species
100
What vocab term means "survival of the fittest"
natural selection
100
Who was the winner of March Mammal Madness?
Humpback Whale
200
What type of structure is this:
Species have in common due to common ancestry (same structure, different function)
Homologous Structure
200
True or false: species with more branch points on their path are more evolved
False
200
How is artificial selection different from natural selection?
it involves human choice of desired traits
200
What islands did Darwin travel to that lead him to develop the Theory of Evolution?
Galapagos Islands
300
What type of structure is this:
Species have in common due to similar selective pressures (different structure, similar function)
Analogous Structure

What type of structure are these wings?
Analogous Structure
400
According to this cladogram, are primates more related to amphibians or rodents/rabbits?
Primates are closer to rodents/rabbits
400
Define "species"
group of organisms so similar, they can produce offspring that can also reproduce
400
How does the fossil record show evidence of evolution?
can watch species change over time
500
What type of structures are these?
Vestigial Structures
500
According to the cladogram, is venom (the orange) a homologous or analogous trait?
Analogous (not from common ancestry)
500
What determines evolutionary fitness?
How well an organism can survive and reproduce
500
Based on this cladogram, did humans evolve from chimps?
Nope! They share a common ancestor though
