Types of Evidence
This type of evidence is from remains or traces of life, which gives us an idea of what life looked like in the past.
Fossil Evidenence/PALEONTOLOGY
Where can the oldest fossils be found in layers of rock?
What is the definition of a species?
A group of organisms that can interbreed.
In a phylogenetic tree, humans and chimpanzees are connected by an organism in the past. This organism is their ___________
Common Ancestor
Mechanisn where organisms inherite traits that makes them survive and reproduce succesfully. Give the name and finger
Natural selection and thumb
Comparative embryology, which compares embryos of various species, have revealed that vertebrate animals share a _____________ with each other.
Common Ancestor
When comparing DNA sequences, the organisms with the (most/least) differences are the most related.
Least
A group of deer are suddenly separated by a flood. Over time, the two subgroups of deer evolve into different species. What type of evolutionary pattern does this represent?
Divergent evolution
Father of evolution
Charles Darwin
Mechanism that has random changes in the dna sequence. Name and finger
Mutation and middle finger
Comparative Anatomy, which compares body structures, have revealed ___________ structures, which once served a function, but no longer do.
Vestigial
Homologous
A group of organisms live in the forest. Over time, they evolve together. What type of evolutionary patterns is this?
Coevolution
Homologous structures are a result of which type of speciation?
Divergence
Mechanism where alleles move from one population to another. Name and finger.
Gene flow and index/pointer finger
Comparative Anatomy, which compares body structures, have revealed ___________ structures, which have different functions but the same evolutionary origin.
Homologous
Whales contain fermur bones. These are examples of _____________ structures.
Vestigial
When similar species become more different over time, we call this _1__________. When different species become more similar over time, we call this _2________.
1.Divergence / 2.Convergence
Analogous Structures are the result of which type of speciation?
Convergence
Mechanism where the populationi shrinks due to natural disaster or event.
Genetic drift and pinkie finger.
____________ is the most accurate evidence, in which we compare __________ of various species.
Biochemistry / DNA or Protein)
Whale flippers contain different bone structures to shark fins. These are ____________ structures.
Analogous
Darwin's Finches all evolved slowly into a dozen different species around the same time. This is called?
Gradualism
What were the four types of physical evidence of evolution that we learned this year?
Fossils, Comparative Embryology, Comparative Anatomy, Comparative Biochemistry
Mechasnism where sexual selection occurs. Name and finger.
Non-random mating and ring finger.
