Darwin noted changes in the earth and he read Lyell’s geology book. Also gathered fossils.

Question 5

Who came up with the idea of evolution by natural selection independently?

Answer 5

Alfred Russel Wallace and Charles Darwin

Question 6

Who’s work was Lyell’s work based off?

Answer 6

James Hutton

Question 7

Darwin’s conclusions that species?

Answer 7

Evolved into current forms where they were.

Only evolution can explain common traits.

Question 8

Darwins conclusions that species?

Answer 8

Evolved into current forms where they were.

Only evolution can explain common traits.

Question 9

When did darwin start writing?

Answer 9

1844, wallace and darwin started to connect 1858.

Question 10

Alfred Wallace

Answer 10

Had an identical view on natural selection as Darwin.

Question 11

A theory in biology is most similar to:

Answer 11

A law in physics

Question 12

Theory

Answer 12

Overarching set of mechanism/principles that explain a major aspect of the natural world.

Question 13

Hypothesis

Answer 13

The explanation for an observation, phenomenon, scientific problem that can be tested by experimentation.

Question 14

Instead of evolution, Darwin liked to say

Answer 14

Descent with modification

Question 15

What did anatomist note?

Answer 15

Similarities of structures between different species.

Question 16

Homology

Answer 16

Having the same relation in position or structure; from a common ancestor.

Question 17

Common descent idea?

Answer 17

Idea that all species are related and came from a common ancestor.

Question 18

Common trait of mammalia?

Answer 18

Milk production.

Question 19

Traits that are similar (but different) in two or more species because they were modified from a trait in a common ancestor are called:

Answer 19

Homologous characterisitcs

Question 20

Before darwin vs when he studied natural selection.

Answer 20

there should be a more simple explanation to evolution: natural selection. Vs great chain of being, nervous fluids, etc.

Question 21

Thomas Malthus

Answer 21

Economist, influences Darwin/Wallace.
Notedpopulations would always outgrow resources.
Noted organisms grow and reproduce quickly.

Question 22

Natural selection

Answer 22

differences in phenotypes of indv. that allow them to survive/reproduce better.

Question 23

Logic behind NS Fact 1

Answer 23

All species have great potential fertility that their pop size would increase exponentially.

Question 24

Fact 2

Answer 24

Except for minor fluctuations and occasional major fluctuations, population size is normally stable.

Question 25

Fact 3

Answer 25

Natural resources are limited. In stable env, they are relatively constant

Question 26

Inference from fact 1-3

Answer 26

More indv are produced than can be supported, therefore, struggle for existence, which only a small progeny survives, which those who survive will be the progeny of the next generation.

Question 27

Fact 4

Answer 27

No two indv are the same

Question 28

Fact 5

Answer 28

The variation is heritable

Question 29

Inference from those facts

Answer 29

Survival from the struggle is not random but depends on inherited traits, this unequal survival defines natural selection.
Continuing gradual change in populations over generations, eventual lead to a different/ new species.

Question 30

What else to darwin write about?

Answer 30

Sexual and human selection/evolution.
Heredity/genetics (Mendel)
DNA

Question 31

Techniques today

Answer 31

molecular biology

modern synthesis- genetics, paleontology, ecology.
