Chapter​ ​4:​ ​(Evolution:​ ​History​ ​and​ ​Evidence) 

Why did darwin deserve the credit for his theories of evolution?

1.) Evolutionary​ ​change​ ​by​ ​Greek​ ​Philosophers:​ (Aristotle and Empedocles) primitive concepts of change in living organisms over time

2.) Evolutionary​ ​change​ ​by​ ​Buffon:​ considered change DEGENERATE (apes are degenerates of humans)

3.) Evolutionary​ ​change​ ​by​ ​Lamarck​: change results from NEED, species do not go extinct they evolve into different species, GIRAFFES We also discuss several other topics like what evidence suggests that life arises relatively easily?

4.) Evolutionary​ ​change​ ​by​ ​Malthus:​ essay "Human Populations" said that humans have great ability to reproduce, but resources limit this.

What is parasitism?

5.) Evolutionary​ ​change​ ​by​ ​Wallace​: had very similar theory of evolution as Darwin, published ideas with him, but gave him most of the credit We also discuss several other topics like - How many ways to get a 50-dip ice-cream?

6.) Evolutionary​ ​change​ ​by​ ​Darwin​: theory of evolution, natural selection, Galapagos findings

7.) How long did Darwin spend in the Galapagos Islands?: 5​ ​weeks

8.) What​ ​was​ ​Darwin's​ ​first​ ​publication​ ​and​ ​what​ ​was​ ​it​ ​about?:​ On Origin of Species by Means of Natural Selection, variation between different species in different habitats 9.) How​ ​did​ ​George​ ​Lyell​ ​shape​ ​Darwin's​ ​ideas?:​ suggested that the earth is older than 6,000 years, made him think life forms must have changed if the earth changed. 10.) How​ ​did​ ​fossils​ ​influence​ ​Darwin's​ ​ideas?:​ he found a primitive giant sloth that was very similar to modern sloth, suggested that change occurs

11.) How​ ​did​ ​the​ ​Galapagos​ ​Islands​ ​shape​ ​Darwin's​ ​ideas?​: tortoises and finches were different on different ends of the islands

12.) Why​ ​did​ ​Darwin​ ​deserve​ ​the​ ​credit​ ​for​ ​his​ ​theories​ ​of​ ​evolution?:​ he did years of work and accumulated tons of evidence We also discuss several other topics like Who is the director?

13.) most​ ​compelling​ ​evidence​ ​for​ ​evolution:​ fossils

14.) adaptive​ ​radiation:​ ​formation of new forms from an ancestral species (ex. Galapagos finches)

15.) artificial​ ​selection:​ choosing certain traits to carry on (dog breeds) 16.) 4​ ​ideas​ ​of​ ​theory​ ​of​ ​evolution​ ​by​ ​natural​ ​selection: We also discuss several other topics like What is meant by the gain of a control system?

a.) organisms have high reproductive potential

b.) inherited variation exists

c.) limited resources doesn't support reproduction potential

d.) adaptive traits become more common in each next generation

17.) How​ ​does​ ​adaptation​ ​occur?:​ comes from chance mutations that end up allowing animal to reproduce and survive more effectively than before mutation (natural selection) 18.) What​ ​is​ ​inherited​ ​in​ ​adaptation?:​ variation We also discuss several other topics like epidermal cells that are actively mitotic

19.) natural​ ​selection:​ only fittest survive, best traits that allow for best chance of reproduction end up being passed down

20.) microevolution:​ ​change in frequency of alleles in a population over time (ex. antibiotic resistance)

21.) macroevolution:​ large-scale changes, result in the extinction and formation of new species (ex. a species split in two)

22.) biogeography:​ ​study of geographic distribution of plants and animals 23.) What​ ​do​ ​biogeographers​ ​do?:​ attempt to explain distribution patterns 24.) paleontology:​ study of fossils

25.) fossil:​ evidence of plants and animals that existed in the past and have become part of earth's crust

26.) analogous​ ​structure:​ various structure in organisms have the same appearance, but evolved separately (bird wings and fish fins)

27.) convergent​ ​evolution:​ unrelated organisms evolve to have similar structures (birds and insects)

28.) homologous​ ​structure:​ resemblance that occurs because of common ancestry (bones in limbs of most animals)

29.) How​ ​do​ ​we​ ​know​ ​that​ ​almost​ ​all​ ​vertebrates​ ​evolved​ ​from​ ​the​ ​same​ ​vertebrate?​: all have same bone structure (whales have vestigial pelvic bones)

42.) How​ ​does​ ​biogeography​ ​give​ ​evidence​ ​of​ ​evolution?:​ different species across the world came from same ancestor (jaguars in south america and leopards in asia) 43.) How​ ​does​ ​paleontology​ ​give​ ​evidence​ ​of​ ​evolution?​: fossils give evidence of ancestral forms of modern animals (big sloth fossil very similar to modern day sloth) 44.) How​ ​does​ ​the​ ​molecular​ ​record​ ​give​ ​evidence​ ​of​ ​evolution?:​ molecular clock dating (changes in DNA within a species over time)

45.) How​ ​does​ ​embryology​ ​give​ ​evidence​ ​of​ ​evolution?:​ embryos with similar ancestors go through similar developmental processes
