Chapter 5: Evolution of Biodiversity
Species richness
Species evenness
Evolution by natural selection
Evolution by artificial selection
Founder effect
Founder effect reminds me of the bird from Finding Nemo and how once all birds had the exact same features but when some when to a the ocean they eventually had to evolve into has have longer beaks in order to eat fish
I remember this with an example of humans injecting chickens so they become large/ when humans screw everything up
I remember this as what happens when humans aren't involved
I remember species evenness by the word even and whether one population outnumbers another
I remember what species richness is because the word rich reminds me of how much of something there is/ an amount
Realized niche
Niche generalist
Niche specialist
Species that can only survive under specific conditions
Like giant pandas that need bamboo forest in order to survive
A species that can adapt to any condition
Humas can adapt to any condition
determines where a particular species lives
Includes living and non living components
How a species needs to adapt to something
Allopatric speciation
Geographic isolation is when an organism is separated from its species so they cant't breed anymore
When a new species is created due to geographic isolation
Sympatric speciation
When a new species is created from one species creating a link to them
Phylogenetic tree
The evolution of specific species and how closely they relate to each other
Genetic Drift
Bottleneck effect
Reduction in population of a species and their genetic diversity
Usually happens because of humans and natural disasters
A small population losing a specific gene
Genetic drifts are usually part of the founder effect and bottleneck effect
Can also happen because of random mating
Kind of like a family tree of animals and plants
Makes me think about how cats and lions are in the same family
Polyploidy cells contain more than two pairs of chromosomes
One becomes two
It's kind of like a long distance relationship
