Life Ascending
Hot Blood
Evolution
Fungi can't survive in hot temp
Allowed night foraging
more Mitochondrion = more heat given off
leaky mitochondrion releases heat
XS carbon digested and releases heat instead of growing bigger
Death
Evolution
Punish cells in multicellular
Caspase enzymes
Life is balance between Apoptosis and porliferation
Old age disease aren't selected out
Mating vs. Age
Energy sanctioning
Life
Life=replication
3.8 billion year ago
At volcanic vents
naturally occurring compounds
High temp
Acid alkali reactions
Natural proton gradient for chemiosmosis
Mineral cells (LUCA)
Krebs cycle could occur (with addition of ATP)
DNA
Bases provide attraction between both strands
each base determines something different
Evolution of DNA
RNA World
RNA actes as protein and genetic info
RNA to DNA in mineral cells (natural selection of RNA
2 letter codon to 3
DNA more stable
In mineral cells ATP and proton grad provided
Photosynthesis
Recite steps
allowed respiration to occurr
Cyanobacteria symbiosis after ingestion of chloroplast
Sex
Evolved through
Cell fusion (cell wall)
Segregation of chromosomes
Recombination machinery (from bacteria)
Cons
only 50% passed on
Good genomes can be reshuffled
STI
Energy wasted looking for mate
Pros
Genetic diversity
Protection from disease
Mutations can accumulate
Consciousness
Extended consciousness
role in society/language (humans)
Primary Consciousness
Pain, emotions, motivations (animals)
How?
40Hz
neural map
Body feedback + sensory info
neurones are selected
Quantum coherence
Movement
Motility = speed of evolution
more AR/niches
Plants evolve slower
Plants co evolve with pollinators
Physiology
Cytoskeleton
Microtubules/microfilaments
Actin/myosin track and motors
Kinesins
Muscles
Different types have different specialties
contraction speed
long term short term
power/endurance
Complex Cell
Nucleus Evolution
Protection from jumping genes
Allowed RNA scissors to cut mRNA before translation
Allowed a swell in genomic material
Phagocytosis by symbiosis
Can't have evolved naturally as bacteria breath over skin, so bigger=less SA for respiration
Once fateful encounter had occurred it breathed from mitochondrion rather than over membrane allowing a swell in size
Therefore phagocytosis occurred by symbiosis "the fateful encounter"
A bacteria got inside an Archaea (by chance and wasn't digested)
Sight
More complex predator-prey relationships
Evolution
Retina
Rhodopsin
Photoreceptive cells
Sensitive to light
In cyanobacteria
Lense
Crystallised proteins
Found in cytoskeleton form crystal lattices
Varies a lot across species
Resolution
