🦍 Australopithecus and the Transition to Bipedalism

Paragraph 2 discusses the Australopithecus group, which lived in African jungles from about 5 million to 1 million years ago. This group is significant as it represents a transitional phase in human evolution, with species like Australopithecus anamensis and afarensis. These hominids were bipedal, walking on two feet, and had brain sizes larger than their predecessors, although still smaller than modern humans. They were tool users but not tool makers, utilizing sticks and stones for digging and were scavengers with a diet that included insects, plants, fruits, and sometimes meat. The paragraph also differentiates between the gracile and robust types of Australopithecus, with the latter having larger teeth and jaws, indicating a more muscular build.

10:08

🛠 The Emergence of Homo and Technological Advancements

Paragraph 3 introduces the Homo genus, which includes Homo habilis, Homo erectus, and Homo sapiens. It highlights the evolution from Australopithecus to Homo, focusing on the development of bipedalism and the increasing brain size. Homo habilis, known as 'handyman,' is recognized as the first true human due to its ability to make and use stone tools, a significant leap from mere tool use. The video also discusses Homo erectus, which had a larger brain capacity and was the first to use fire, cook meat, and protect against wild animals. This species was also the first to use spoken language, enabling cooperative hunting and social activities. The paragraph concludes by mentioning other Homo species like Homo heidelbergensis and Homo floresiensis, which had unique adaptations to their environments.

15:08

🌟 The Rise of Homo Sapiens and Cultural Evolution

Paragraph 4 delves into the emergence of Homo sapiens, the species to which modern humans belong. It discusses the physical and cultural characteristics of Homo sapiens, including their large brain size, use of fire, and crafting of sophisticated tools. The video also touches on the Neanderthals, a subspecies closely related to modern humans, known for their burial practices and adaptation to cold climates. It contrasts Neanderthals with Homo sapiens sapiens, or Cro-Magnon, who were anatomically modern humans living during the last ice age in Europe. This paragraph emphasizes the cultural evolution that accompanied the physical changes in humans, leading to advancements in technology, art, and social structures.

Transcripts

okay welcome back so for today

will be human origins this is the fourth

module understanding culture society and

politics

biological and cultural evolution

in the previous modules evolution both

cultural and biological but for now

we are going to go in detail okay

humans

okay so we're going to talk about today

evolution both biological and cultural

so as we have mentioned earlier um

not only biologically speaking but also

culturally

but before we go to the cultural

evolution

we have to consider first the biological

changes

so gentlemen concept of the evolution of

man okay

and here um

english is

we have charles darwin he is the author

of

on the origin of species by means of

natural selection it was published

in 1859 and he was the person behind the

concept of natural selection

based on him i wanted to survive

it

it all started with the hominids okay

the hominids is a general term used by

scientists

among early humans and other human-like

creatures

erect during the prehistoric times

these include sahil anthropus

artepiticus

and australopithecus

stage of human evolution and homo as the

last

so yuma before non mahomia needs okay

they're not really uh they're not really

humans but they are human-like

creatures okay so uh these are still

important because yeah that

this is where things started so

primarily

and australopiticus as well as are the

pita cosmetics

ape like and human diet characteristics

biological and culturally modern human

right now but that's just

okay but we are going to continue

studying

this okay so let's start with sahil

anthropus okay

so we have the cilantro ceylanthropus

uh our species that existed six to seven

million years ago

species okay similar

to the australopithecus and modern human

young nila

and their brain size is about 320 to 380

cubic centimeters okay

a modern human case on 1 500 cubic

centimeters

and brain size so nothing difference

they're

relatively smaller and we could consider

okay they have small teeth similar to

other hominids and they could walk

upright okay

okay don't worry

our names of the species

specifically the hominins okay oro into

genensis

existed five

okay so after now sahilandropus

family so you have the artificial kadaba

existed 5.6 million years ago okay

it's for they existed about 4.4 million

years ago

so on ebay seminar depictions made the

major learners it's

ape on the ground okay angra meetus

naman on the other hand

would mean root okay r-o-o-t root

shura

is about four feet okay and then a

weakness that's a 120 pounds

okay

and then the skull size is similar to on

a it has a small brain

and it's biped already so not in some

ipad

creature human neck creature

on two legs or feet because before um

we could consider the aply creatures

before to walk on fours

on two feet and they lived in jungles

and forests like chimpanzees

okay so australopithecus or the southern

ape

was the next group of the hominids okay

african jungle from about 5 million to 1

million years ago

so

was childensis and then we went to the

rdp techos

okay or the ape on the ground and now

we're moving to australopithecus

or the southern ape okay so i'm a

thousand

eight ninja that evolved narendra

500 cubic centimeters it's already

one third of the most human brain

upright uh he is also biped that means

he's walking on

two feet and then they are tool users

okay but not tool makers

potentially but they cannot create their

own

tools yet okay next to this one is that

they used

sticks and stones for digging okay so

they uh they

lived in small small social groups and

there was distance of movement okay as

they searched for stones to be used as

tools

they search because they they are not

actually those who are creating it

and then they are also food scavengers

and they eat

insects plants fruits and even sometimes

meat okay so i'm astrological

me types species

so uh there are but there definitely

there are two major types we have the

gracile and the robust okay

um

okay uh human like creatures

okay they have bigger jaws so

etounaments also

astrology design

for the peter sign me small teeth

so referring to um this the subgroup

mali itam feature okay so under this

group is the australopithecus

australopithecus afarensis and

australopithecus africa

okay you have astral piticus andamensis

from the sound itself so

the robust group it includes

australopithecus

ethiopia australopithecus robustos and

australopithecus

species larger on teeth and jaws and

they're highly muscular especially for

the australopithecus

by saying okay so now imagine nothing

now see

uh grass cell australopithecine selena

smaller

okay and the bigger ones are the

astrologicals

okay so

there is a very um we could remember

lucy it was even

at some point it could be related with

the lucy film okay

so it don't see lucy is a 3.2 million

year old

australopithecus afarensis

so lucy is considered as one modern

human's

earliest ancestor and the disco the

discovering

remains in ethiopia by donald

johansson in november 1974

while they were digging up they were

listening to the beatles losing the sky

with diamonds

so now let's go to the next

category which is the homo okay the homo

first lived in africa

and they were bipedal na again walking

on

on their feet and then it should also

consider that the homo

included homo habilis homo erectus and

homo

sapiens and there are also there are

also details in between

okay so let's talk about homo habits

so homo habilis are practically species

that are also considered as handymen

okay

homo habitees are species uh with the

brain

with the area that is already associated

with speech in mostly humans

and they can already make stone tools so

if we could remember

the earlier uh ver the earlier

species which is the australopithecus

sila users lung

but this one the homo habilis they make

their own stone toes already

okay they have the ability to make and

use tools

in a unique quality to humans such that

the species are considered to be the

first

true human okay the species

uh name means handyman and they lived

about 2.4 to 1.4 million years ago

they were scavenging for food okay

their height is about three to four feet

okay

and their brain size is already half the

size of the modern human

so that's a 700 cubic centimeters nasha

and they made those called aldo one okay

although one

came from the place where these tools

were found which is in

all the george tanzania okay this tools

were used in cutting and made from

volcanic stones

so some basaltic rocks okay

so they also use this tools for hunting

and food gathering okay so

next is we also have the homo ergaster

these are the in-betweens na homo

ergaster

it existed 1.8 million years ago it deal

next homo species

to flourish okay

okay so um we also have another specie

in between which is homogenous fences

this species character were

characterized by a longer face

large molar and premolar teeth so the

imagination

and a larger brain case compared to the

habilis

okay so particularly larger frontal

lobes

and areas of the brain that processes

information

so after me

the species name means upright man with

the body proportions already similar

to that of modern humans they lived

about 8.

1.89 to 143 000 years ago

they adapted to hot climates and they

mostly spread already

africa asia okay their braid size was

about

1 000 cc or about two-thirds not

no more than human size okay so they

could already uh

walk upright and then their height is

about five feet so papasu

some other new one okay they were the

first hunters that improvised tools such

as

access and knives okay and they were

also the first

people or not really people the first

specie

to introduce fire unluckily

um at some point it it made chewing

easier

could be still how we looked okay how

the

earlier humans look like peru

we don't need those so we don't need

bigger teeth anymore okay

so another is another thing about homo

erectus is that

they are believed to be more intelligent

and more adaptable

compared to manga homo habilis okay the

karuna

cultural evolution okay there they began

to invent

okay things uh using uh different

technologies

for

[Music]

okay so they are also skillful hunters

okay it should also be underscored that

they also used

not they introduced the fire and the use

of fire deba

um this allowed them to cook meat and

also to protect themselves from wild

animals okay

so it is also through the homo erectus

that

they're the first homo to be considered

to use the spoken language okay

so then the exchange of ideas planning

of cooperative hunting

okay and then uh they also had these

different activities already

okay so it is

hormone africa

okay so um with that there is the first

fossil found

nah

it was found in the long guppo cave in

china

they lived about 1.9 million years ago

okay

some proof part that they existed is

that they found

a fossil internal java indonesia

by um yujin du bois a dutch

an anatomist and geologist so it is

it is also known as the packing man

which lived about

1.1 to 1 million years ago so

interesting change the homo erectus

in terms of intellectual physical

cultural okay not evolution so let's

move on

okay so we have two species before we

move on to the major

major species after the homo erectus

we have homohedelberginesses and

homoflora florescences

okay so for homohedelbergenesis silicon

species with large

brow rich and short white bodies who

lived about 700

000 to 200 000 years ago in europe and

africa

so they enforced humans to live in a

colder climate and

the first two um hunt large animals in

routine using

spears okay they were the first ones to

construct human shelter

next to them is homo florence and sees

okay

so their species nicknamed hobbit

because

i'm not in the hobbit okay they have

small stitcher

with a height of more or less three feet

and they lived about 95

000 to seven to seventeen thousand years

ago

island and flores indonesia along with

the other

dwarfed um animal species okay

so ayan afterwards kumeron tayong

that means we get to the next um

next specie which is considered to be

a major developments uh evolution of man

so we have

homo sapiens okay homo sapiens

the species species name means

the wise man okay that appeared about

200 000 years ago

this is where the present human race

belong okay

so it's a homo sapiens or the thinking

man

or wise man okay

also homonyms and homo sapiens sapiens

okay your physical anatomy nathan and

their physical anatomy are

really the same okay almost the same and

then here are the characteristics of

homo sapiens so first they have large

brain size 1400 cc

that is almost similar to the human uh

modern humans uh brain size okay they

lived in shelters

their food gatherers they ate plants and

fruits

the selena animals gathered

shellfish which was about 164 years ago

okay 164 000 years ago

they used fire and they crafted metals

already okay

sophisticated na and very um

very uh smoothened

during that time and they have the

technology already in

fishing they have the they have the

they have the arrows the harpoons the

sewing solving needles etc

okay so

okay so we have also the homo sapiens

neanderthalencies that's what i've

mentioned earlier

these species are short yet stocking

body built they adapted to

winter climates especially in icy cold

places

in europe and in asia the subspecies

also known as neandertal man is also the

closest relative of modern humans

they were the first one to have the

practice of burial of the dead

hunting of hunting and gathering of food

sowing of clothes

from animal skin using bone needles they

lived about 200 000

to 28 000 years ago okay

and then of course

uh homo sapiens sapiens me some species

known as cro-magnon okay so

characterized to be anatomically modern

humans and lived in the last ice age

of the of europe from 40 000 to 10

000 years ago they were first they were

the first to produce

art of about 1400 cubic

centimeters okay so micro magnolia

no i know last apart and then we have

the modern humans already

okay so with that we so after that

what we could expect would already be

the modern humans so

nothing in development

so it started with the hominids and then

now we have

you we have us okay so that's it

for the biological evolution or the

evolution of

men credits to the owners of the

pictures that i used to the authors of

the books or the references that i used

for understanding cultural society and

politics

and to the writers of the module that's

it paul

thank you
