When idid the mitochondria and aerobic capacity evolve in euk?
About 2.5 bya
What are some pieces of evidence that support the theory that chloroplasts evolved from Cyanobacteria
They have their own DNA and it is circular. They have two membranes. They replicated separately from the cell.
How did photosynthetic capacity spread through the domain eukarya?
Secondary endosymbiosis
When did simple multicellularity evolve?
Simple-1.2-1.8 bya complex-555-575 may
Is simple multicellularity a homologous or analogous trait in euk? How about complex multicellularity?
Both analogous
What are some reasons experts give for the diversification of multicellular organisms during the Permian?
More oxygen in the atmosphere- almost 60 percent of what it is today which promotes diversity
The pH of the oceans promoted shell formation causing an evolutionary arms race
