Biology - The Study of Living Things
Question: What is Life/Living Things?
Breathing

Reproduction *Note: The ability to reproduce is what makes something living*

DNA

Reactions
-
Theory of the Origin of the Earth
4500 mybp - Origin of Earth - no O2, it was locked in compounds
-
4000 mybp - Origin of Life (bacteria + green and blue algae) - still no O2
Replicator Molecules
○
Algae was able to photosynthesize
○
-
2500 mybp - Oxygenated environment/atmosphere
-
2000 mybp - Origin of Eukaryotic Cells - 1000x larger than bacteria (prokaryotic)
Organelle
○
-
1000 mybp - Origin of multicellular organisms
-
500 mybp - plants colonized land - animals colonized sea
-
63 mybp - Extinction of Dinosaurs
-
1 mybp - First humans evolved in east Africa
Homohabiles (africa)
○
Homoerectus (First to move out of Africa)
○
Homo neanderthalensis (in northern areas, dealt with harsh winters)
○
Homo demesnes ???
○
Homo floresiensis (Hobbits)
○
Homo sapiens (Eastern Africa, savannah)
○
-
Pleistocene Glaciation
Natural selection:
in all living populations, in each generation there are individuals that
survive and reproduce and those that do not, and the next generation is like those that
succeeded to reproduce.
Works on an individual level
Passed on: genetics, physiology, anatomy and behavior.

*Note: mybp - million years before present*

Document Summary
Reproduction *note: the ability to reproduce is what makes something living* 4500 mybp - origin of earth - no o2, it was locked in compounds. 4000 mybp - origin of life (bacteria + green and blue algae) - still no o2. 2000 mybp - origin of eukaryotic cells - 1000x larger than bacteria (prokaryotic) 500 mybp - plants colonized land - animals colonized sea. 1 mybp - first humans evolved in east africa. Homo neanderthalensis (in northern areas, dealt with harsh winters) Natural selection:in all living populations, in each generation there are individuals that survive and reproduce and those that do not, and the next generation is like those that succeeded to reproduce. Natural selection:in all living populations, in each generation there are individuals that. Oparen & haldane - random chemical reactions: small organic molecules produced, molecules became polymerized (chains created, replicator molecules - rna (ribonucleic acid), dna (deoxyribonucleic acid) Plant pathogen - infects plants, death or stunting.
