 Randomness occurs more in small populations but genetic diversity occurs
more in larger populations.
 Types of genetic isolation;
 Mechanical
 Temporal
 Behavioural
 Gametic
 Ecological
Macro-evolution
 As time passes, mutation, nucleic acids, and amino acid substitutions
accumulate. It occurs at a constant rate for a particular gene.
 Convergent evolution occurs when species/animals develop genes
independently due to the same natural selection affecting more than one
place
 Columbus is thought to discover America but it was discovered 15,000 years
ago by Siberians.
 Neanderthals thought to be present 100-300Mya had pale skin and red ginger
hair.
 Neanderthals and humans/ denisovans interbred; humans have 0-4%
neanderthal genome
 De-extinction: Synthetic biology would be used to recreate genomes to bring
back extinct animals.
 Fossils from dated strata are used to infer the timing and order of evolution.
 Giant insects reduced size/ wingspan due to reduced atmospheric oxygen.
 Tetrapods originated from lobe-finned fishes.
 Major transitions in evolution.
 C. Elegans: a free-living nematode found in rotten vegetation mostly in areas
where it’s rainy. They have 5 autosomes and one X sex chromosome.
 RNA is thought to have transited from RNA (from the RNA world) being a
gene and enzyme to DNA. This is advantageous as DNA is a more stable
structure forming a double helix but DNA thereby needs a translation
system.
 Amino acids are thought to be co-factors to ribozymes in the RNA world
enhancing their performance
Why was the cell wall lost in the transition from prokaryotes to eukaryotes?
