Event
Our universe forms.
Our galaxy forms.
Our Star system forms. Every atom in our bodies already existed when the
solar system formed. We are made of stardust! Old stardust.
First rain.
First life elements form in the sea (primordial SOUP).
Bacteria (Maybe 3.5 BYA) We are related to every animal and every plant
that is alive today and that ever lived, through a common ancestor –
bacteria. Yes, we are descendant from apes but bacteria are our oldest
progenitors.
First bacteria divide; clone selves in 20 minutes. (Self-replication.)
Photosynthesis.
Cyanobacteria, the blue-green photosynthesizing stomatolite microbes,
oxygenate the atmosphere.
Prokaryotes (simple single cell organism lacking a nucleus) arose. Natural
Eukaryotes – Single celled organisms with a nucleus & organelles.
Eukaryotic organs are colonies of various prokaryotes. (Self
organization.)
Microbial aerobic respiration commences.
Protoctists form = First established beings, organisms.
Bacteria go on land.
Metazoa - Multicelled organisms. In our lineage.
Cambrian "explosion" (Life forms proliferate.) Note that almost all of the
lifeforms bigger than a microbe that ever lived on earth, came in the last
4% of the age of the planet!
Fish, vertebrates with bilateral symmetry, and later with heads and jaws.
Algae go ashore and start the plant world.
Tetrapods move on shore. They begot amphibians, reptiles (including
dinosaurs and birds), and mammals.
Amphibians (eggs)
Reptiles (eggs)
Mammals. (Placental. Wow! What a difference.)
Dinosaurs (eggs)
Birds (eggs)
End of dinosaurs; mammals start their rise.
Primates (Monkeys). Maybe 70 MYA. Dryopiths = arboreal.
Hominoids - Apes came out of the trees and split from the Old World
monkeys. Apes (are tailless and have opposable thumbs) = gibbons,
orangutans (90%), gorillas (90%), and chimpanzees (98.4%). (Genes
like ours). 390 to 550 cc brains.
Procounsel africanus – The early apes with some hominid features, taken as
Ramapithicus. Man or ape? - Ape. Pre Orangutan. About same range as H.
erectus. 1st ape wave out of Africa?
Orangutans split from great apes. (Maybe 18 MYA.)
Gorillas split off from great apes.
Shelanthropus tchadensia. Chad. A missing link? Yes, branched off to
Chimps and to hominids. 320 - 380 cc More hominid than chimp. To 6
MYA.
Orrorin tungenensis. Bipedal. In our line? Tungen, Kenya. Chimp size.
Chimps remained non bipedal apes.
Hominid family (Maybe 4 MYA) – Bipedal Apes (our line) diverged from apes
(pre-chimps) via missing links. One such may have been Ardipithecus
kadabba found in Ethiopia; 5.7 to 5.2 MYA.
Ardipithecus ramidus (bipedal walker) – to 3 MYA. 1/3 brain size. Hadar
Ethiopia. Likely to have evolved into Australoithecus. Was one of our
ancestors but not the chimps. To 4.2 MYA.
Australopithecus anamensis (Southern ape-man). To 3.9 MYA.
A. afarensis (Lucy) (for the Afar people of Hadar, Ethiopia) – Bipedal. 1.2m
tall; 380 – 450cc. Could be from 5 MYA to 2.9 MYA.
Kenyanthropus platyops (Flat faced man of Kenya) Lomekwi, Kenya. May
be an arfaensis. To 3.2 MYA.
First evidence of stone tool use, in the Dikika region of Ethiopia.
A. africanus (gracile) – to 2 MYA (May be in our line.) Sterkfrontein, South
Africa. 1.4m; 400 - 600cc. To 2.0 MYA.
Paranthropus aetheopicus. W. Turkana, Kenya. To 2.5 MYA.
A. garhi (surprise) Bouri Formation, Ethiopia.
Homo habalis (handy man) – to 1.44 MYA. ½ brain size: 700 - 800cc.
Olduvai Gorge, Tanzania. Stayed in Africa? No, 1st out of Africa, prior
to 1.7 MYA.

habilis. Same span as habilis. 700cc.
H. dmanisi – in Georgia and Java. Links Habalis to Erectus. 600-700 cc.
Paranthropus robustus To 1.6 MYA. 530cc. S. Africa.
P. boisei. – to 1 MYA. Extremely robust. 410 – 510cc. Olduval Gorge,
H. ergaster (Working man) (In our line) Koobi Fora, Kenya. 1000cc. Some
H. ergasters stayed in Africa. Some left and begat H. erectus abroad.
Homo erectus – to 200 KYA. Ranged from Spain to England to South China
(Korea) to Philippians. 800 – 1000cc.
Evidence of fire being used by man. (760 kYA in N Dead Sea)
First hand axes.
Out of Africa "#1" starts – H. erectus. (Really #2, and ~1.5 MYA)
H. heidelbergensis – In Europe. 3rd wave? 600? or 355? to 100 KYA.
H. erectus in Near East.
H. erectus in Java – Java Man. (Maybe 1.5 MYA?)
H. erectus in China – Peking Man
H. erectus in England – Boxgrove Man.
Gawis (Hadar region) cranium 500 to 200 k years old. Homo _______
First hut. Found in France.
H. sapiens (thinking man) - us! At Omo River Ethiopia. Full brain size
–1200-1600cc. As smart as us! They had no books so they had to
memorize everything. Probably used more of their brain than we do.
Caused the extinction of many animals. 160? or 100? KYA to present.
First wood spear, in England.
H. neanderthalenus – to 25 KYA. Advanced stone tools. Withstood
Europe’s Ice Ages best of hominids. Painted caves. Buried dead with

came from H. h.
