On Monday we learnt a little about linear equations.
Then we used what we did last week to make a plan for an explanation text. We added to it using Google.
Here is our planning.
Next, the person who planned each paragraph has to write their information into a paragraph in their own words. When we put it all together, it will make a detailed explanation text.
Dawrin’s theory
Charles Darwin was born 12 February 1809 and died 19 April 1882
He was a scientist who studied living things. He travelled around the world on ships, studying different kinds of animals and birds.
Released a book in 1859 called The Origin of Species.
His idea was that all living things originated from one common ancestor and evolved over millions and millions of years
The idea of natural selection means that animals/organisms with desirable traits (e.g. things about them that helped them to survive, like their size, camouflage, long neck, etc) would survive and pass their traits onto their children. The ones with undesirable traits (e.g. too small, too slow, couldn’t hide, couldn’t fight back) were eaten and their traits were not passed on
Released another book called The Descent of Man in 1871 which talks about human evolution specifically.
How animals evolved from water to live on land - EH HTOO
Early fish started to go coles to land then after a long time the fish involved to go on land for a short time there limbs got stronger then the fish involved to have lunges then the first amphibian like animals come about after years of evolution it was the rain of the.
First had to evolve stronger rib cage, shoulders and limbs to hold up its own body weight
Hominins - (Mariah) (Railey)
Lived in Africa
Had grasp
6 million years ago
130cm tall
Weighted for about 35kg
Hominins used to draw things in caves
The first Hominins appeared around 3 million years ago.
The old Hominins lived for 5.8 million years ago
Were bipedal
They have a family
They eat hard item such as seeds and nuts
Are close related to humans or homosapin
Homo habilis - Hope
Used tools
Lived 2 million years ago
Bipedal with no grasping feet
3 to 4 million years ago
Family is Hominidae
Were only on average 4 to 3 inches tall
1.44 million years old
Mark leakly discovered homo habilis
Were flexible
Were versatile
Were able to eat tough food like leaves and woody plants
Lived in small groups
Most ancient representative of human genus
Inhabited parts of sub saharan africa from roughly 2.4 - 1.5 million years ago
Had several teeth in the lower jaw
The homo habilis brain ranged in size from 550cm cubed to 687cm cubed
The tools made by homo habilis were made from volcanic rock cobbles
Homo erectus Michael and Davlyn
They had Large brains.
They were the first to leave Africa they went into Europe/Asia.
They had Dexterous Fingers which means they can use them.
They are Bipedal which means they have long legs.
By 800,000 years ago, they used fire to cook food
Homo erectus is an extinct species of archaic humans from the pleistocene.
Homo erectus Height is 1.4 to 1.8m.
Their brain size is 550-1,250 cm
They weight about 41 kg to 65 kg
They are found in Africa, Aisa and perhaps Europe
Appearance: human-like body proportions and upright stance, a protruding brow ridge, large face and no chin. Lived: from about two million years ago until at least 250,000 years ago.
Homo neanderthalensis (Neanderthals) - Wesley.
Lived in southern europe / Asia
Existed around 1,000,000 years ago
Came out of Africa 200,000 million years ago
large nose, strong double-arched brow ridge, relatively short and stocky bodies.
Height about 1.50-1.75m
Neanderthals lived alongside early modern humans for at least part of their existence.
Some modern humans have 2% neanderthal DNA
Neanderthals evolved in Europe and Asia while modern humans - our species, Homo sapiens - were evolving in Africa.
Their front teeth were large, and scratch-marks show they were regularly used like a third hand when preparing food and other materials
They are modern humans closest relatives
Monkeys are there closest to their relatives
Made their own spears and flint handaxes.
Some evidence to say they looked after their sick and buried their dead,
They ate large mammals that they caught, some fungi (e.g. mushrooms) and some plants
Neanderthal - named after an area called Neander Valley in Germany where fossils were found
Homo sapien - (nitika and kymani)
Adaptable to different climates
sapiens is the only surviving species of the genus Homo.
Sapien is another human but their brains were not as smart as our brains today.
Lived all around the world
The Life span is 79 years (good Job)
Interbreed with the other spe
They are highly intelligent primate
Homo sapiens sapiens is the name given to our species if we are considered a subspecies of a larger group. This name is used by those that describe the specimen from Herto, Ethiopia as Homo sapiens idàltu or by those who believed that modern humans and the Neanderthals were members of the same species sapiens. During a time of dramatic climate change 300,000 years ago, Homo sapiens evolved in Africa
sapiens is the only surviving species of the genus Homo. Modern humans are sometimes called "anatomically modern humans". Homo sapiens considers itself the most influential species on the planet, but many species of life, mostly plants and protists, have had a much greater effect on the outside of Earth and its air.
They were naked at that time cause they had no clothes and shoes
Male Homo sapien height is 1.7cm female 1.6cm
Here is our completed Explanation text.
The evolution of humans can be easily seen through their Latin translations; Hominins (man), Homo Habilis (able/handy man), Homo erectus (standing man), Homo neanderthalensis and Homo Sapian (wise man). Over millions of years these creatures changed and developed. Charles Darwin’s theory of evolution explains how we got to be the modern humans we are today.

Theory of evolution
Charles Darwin’s ‘theory of evolution’ was made famous in 1859 when he published his book called ‘The Origin of Species’. In this book, he talked about the idea that all living things originated from one common ancestor and evolved over millions and millions of years. He also introduced the idea of ‘natural selection’. Natural selection means that animals/organisms with desirable traits (E.g. things about them that helped them to survive, like their size, camouflage, long neck, etc) would survive and pass their traits onto their children. The ones with undesirable traits (e.g. too small, too slow, couldn’t hide, couldn’t fight back) were eaten and their traits were not passed on. His ideas were accepted by scientists around the world as he had been studying different species around the world for decades.

First land organisms
The first organisms to venture onto land (apart from plants) was around 30 million years Ago. A fish called coelacanth was one of the first to venture onto land - into a shallow marine environment. Scientists think it was either looking for food, avoiding predators or laying eggs in the shallow waters. It had to develop a stronger rib cage in order to support its body weight out of water (as in water all things are more buoyant). Over time, they also evolved lungs so they could breathe, and their fins became more boney and became strong legs which helped them move. Years after the first amphibian-like animals came along the first one had fins and years after it had half fins and legs after a lot more years it has all legs.

Hominins
Hominins are the earliest version of a human that we know of. For about 6 to 5 million years ago hominids/ancestors have been known to live on planet earth located in Africa. They were around 130cm tall and weighed about 35kg. Hominins used to draw things in caves. They eat hard items or food such as seeds and nuts. Hominins are closely related to humans or homosapin. And the first hominins that step foot on Africa or New Zealand 3 million years ago. And the olds hominins live for 5.8 million year. They were bipedal. They had grasp too. And they have family. Hominins evolved and turned into a human.

Homo Habilis
Homo Habilis lived 2 million years ago. The person the first discovered homo habilis was Mark Leakly. Homo Habilis were flexible and versatile. They were also to eat tough food like leaves and woody plants and they also eat meat by scavenging from animal carcasses. Homo Habilis were the first kind of human to make/use tools. Their family is Hominidae and live in small groups. Homo Habilis inhabited parts of Sub Saharan Africa from roughly 2.4 to 1.5 million years ago. They also have several teeth in the lower jaw and have bipedal with no grasping feet; limiting them to a life on the ground. They are the most ancient representative of the human genus and their brain ranged in size from 550 cm cubed to 687 cm cubed. The tools made by Homo Habilis were made from volcanic rock cobbles.

Homo erectus
Homo erectus had Larger brains then the homohabilis. They were the first to leave Africa around 1.5 million years ago, then the homo erectus went into Europe/Asia. Their hands used to look like a foot but then it changed into a hand, then they had Dexterous Fingers which means they can use them. Homo erectus is a Bipedal which means they stand on two long legs. By 800,000 years ago, they used fire to cook food. Homo erectus ate meat and crisp root vegetables, they ate small animals and ate animals many times larger than their own body size, such as elephants, rhinos, buffalo, and giraffes, whereas chimpanzees. Homo erectus is an extinct species of archaic humans from the pleistocene. Homo erectus Height is 1.4 to 1.8m. Their brain size is 550-1,250 cm. They weigh about 41 kg to 65 kg. The homo erectus fossils are found in Africa, Asia and perhaps Europe. Their appearance is human-like body proportions and upright stance, a protruding brow ridge, large face and no chin.

Homo neanderthalensis
Homo neanderthalensis lived in southern Europe and Asia. They are commonly called Neanderthals, named after a region in Germany where fossils were found. They existed around 1,000,000 years ago and are often depicted hunting ice age animals such as mammoths. Their height was around 1.7m. Neanderthals lived alongside early modern humans for at least part of their existence. They had large front teeth; scientists think they used these like a third hand when preparing food and other materials. They lived peacefully and had children with other types of humans. Homo neanderthalensis looked after their sick and buried their dead. They were mammals. Neanderthals could make their own spears and flint handaxes. They used their tools to kill large mammals and eat them. Their skulls were like the same size as homo sapiens; they had a large nose, strong brow bridge. Scientists think that their stocky bodies and wide open nostrils helped them survive colder climates.

Homo sapiens
Homo sapiens is the scientific name for modern humans. It is the only extant homo species (not extinct). Homo sapiens first migrated from Africa 70-50,000 years ago and lived in Southern Asia and Europe. Males were around 1.7m tall and females around 1.6m tall. They ate meat gathered by killing animals, plants and fungi. They lived at the same time as some Neanderthals, and lived peacefully alongside them, even interbreeding with them. Some modern humans have upto 2% Neanderthal DNA in them.
Ideas and draft by Saia, Kymani and Nitika, rewritten by Miss Ashley.
Over time, humans grew bigger and taller, travelled across continents, learnt to make and use tools/weapons, learnt to cook food, and grew bigger brains.
very good room 8 yous know a lot about evolution
ReplyDeleteWow awesome room 8 yous did a good job on your work hopefully I see more of this awesome work keep up the great work
ReplyDeleteHi Rm 8, I really like your work that you've completed and I've learnt a lot more about genomics and what is evolution I'm so stoked to find out more with your guys help thanks!
