This discovery was concluded that evolution in humans has stopped.

Although it is thought that evolution in humans has stopped, there are two distinct theories that state human evolution is still occurring.
1. One theory states that the environment forces have stopped contributing to human evolution. Sexual  selection is now "driving" human evolution.
2.This theory states that the human body will only continue evolving through artificial selection. Robotics and genetic engineering will be what changes, and evolves humans by upgrading them through enhancement and tech implants.

The genes can be mutated, resulting in new or altered traits, which makes up for the genetic variation that we see today. And when these differences become more common or rare in a population, that is when evolution occurs]]> 2018-10-11 13:11:12 UTC https://padlet.com/jocelyn_shih/22m2br9dkd1r/wish/291698711 Will there be a time when all living things stop evolving? ~Catrina https://padlet.com/jocelyn_shih/22m2br9dkd1r/wish/291699259 Animals and humans are constantly evolving. They change in different aspects to adapt more favorable physical features for the environment they are in. For this reason alone, organisms will continue to evolve over time to adapt to the ever changing environment.  The only case in which organisms will stop evolving, is if the environment stops changing. If the organisms are in the most favorable form when the environment stops changing, they will stop evolving.]]> 2018-10-11 13:12:05 UTC https://padlet.com/jocelyn_shih/22m2br9dkd1r/wish/291699259 What came first, the chicken or the egg? - Kevin P https://padlet.com/jocelyn_shih/22m2br9dkd1r/wish/291699269 The answer is the egg. Millions of years ago before chickens existed there were two different bird like animals. When these birds breeded they created a egg and when this egg hatched it was a genetic mutation (mix of both parents). That genetic mutation millions of years ago is what we know today as chickens. Therefore, the egg came first from  a genetic mutation of two different birds millions of years ago.]]> 2018-10-11 13:12:06 UTC https://padlet.com/jocelyn_shih/22m2br9dkd1r/wish/291699269 What are other signs of evolution in the human body? - Elisha G. https://padlet.com/jocelyn_shih/22m2br9dkd1r/wish/291699346 WE ARE ABLE TO DRINK MILK
The ability to digest lactose shut down around the time that humans did not consume animal milk, and only consumed milk from their mothers. However, when humans began to consume animal milk, people were genetically mutated to be able to digest lactose. Tolerance for consuming lactose dates back 3000 years ago in East Africa and the genetic mutation is now carried by 95% of Norther European descendants.
WE ARE LOSING OUR WISDOM TEETH
Millions of years ago, humans used to have a wider jaw to help chew tough roots, nuts, leaves and meat, requiring more teeth (wisdom teeth). Now, humans use utensils to cut up food and cook foods to soften our food. Humans don't require our set of wisdom teeth, therefore explaining why we have smaller jaws in comparison to early humans. ]]> 2018-10-11 13:12:13 UTC https://padlet.com/jocelyn_shih/22m2br9dkd1r/wish/291699346 What kind of changes in our evolution can we predict based on global warming issues-- Annie~~ https://padlet.com/jocelyn_shih/22m2br9dkd1r/wish/291699482 Global warming has caused our environment to change dramatically. The increasing amount of heat produced by greenhouse effect is melting glaciers and sea ice, shifting precipitation patterns, rising sea levels, etc. Extreme weathers are more likely to happen, such as droughts, floods, hurricanes and other strong storms. Species including plants, animals and even bacterias will need to change themselves in order to adapt to the rapidly changing environment. Generally, these changes of living environment or habitat are mediated by 3 kinds of responses.
The first way is via plastic reactions (a kind of behavioural responses). The second way is by shifting geographically to track optimal conditions, for example, the migration of species towards the cooler poles because of global warming. The third way is the genetic adaptation, or evolution, which is what we are focusing on in this unit.
Paleoecological studies ( normally from fossils) suggest that species actually had the resilience to the past climatic warming(which were relatively more graduate and slower than modern climate changes). A part of them processed adaptive variation and mutation, altered their fitness traits, and made an evolutionary response. On the other hand, the parts that weren't able to quickly adapt to the environment actually experienced local extinction or total extinction.
There are lots of uncertainties and possibility in the predictions of the future changes of our evolution. However, it is indicated that the prediction related to the future ecosystem is definitely not positive because of the effects caused by humans have made the global temperature increase much faster and more rapid than before. The species won't be able to get a long period of time to go through the evolution process (like what they have done in the past, it usually took millions of years and numerous generations to happen) A large scale of extinction among species may be happening shortly.
At the same time, the survivors may need to evolve special skin (greenhouse gases, ultraviolet light, and even radiations), lung (air pollution and increasing amount of Co2), sweat gland (increased temperature), etc. They may become smaller in size in order to consume less energy, escape from frequently occurring extreme weathers and adapt to their reduced and destroyed habitats.

Or are we done?- Aldrin Duque https://padlet.com/jocelyn_shih/22m2br9dkd1r/wish/291699630 Over the past 40 000 to 50 000 years humans have not really changed biologically suggesting the the evolution of humans as of right now is slow due to our environment. In order for us to evolve there must be a significant change in order for us to adapt. Although there has not been much of a biological change we are still evolving slowly due to no significant change in the environment.

This explains how humans evolved from apes, yet apes still exist in the world. The stages in evolution do not end once a new branch is created or the species evolves. The perception that once a species evolves, the last generation of the same species becomes extinct is incorrect. The species simply branch off and evolution continues.

These traits are passed down during reproduction but when mutations occur, the genes can be changed. Overtime, we begin to be able to see the small changes that have occurred through the generations. Different species and organism may change overtime due to their adaptation to the environment.
Ie) the giraffes overtime their necks became longer and longer because their was a greater survival rate, so over a large amount of time, their necks were long.

Overtime humans may become more or less exposed to mutations, which creates changes in our genes and can lead us either towards or away from different diseases. The constant change of the environment also influences our evolution because it pressures us to adapt to a new environment and we change as we learn how to adapt. ]]> 2018-10-11 13:14:07 UTC https://padlet.com/jocelyn_shih/22m2br9dkd1r/wish/291700551 Can the opposite happen and overtime we go back to apes?-Nicole https://padlet.com/jocelyn_shih/22m2br9dkd1r/wish/291701029
The changes from apes to humans have occurred over the years due to environmental changes, however humans did not evolve from chimps. Evolution does not go backwards or forward, it is about the adaptation of a species to it's environment. The environment a million years ago is different from the environment now a days, meaning that due to these factors humans will not change back into apes. ]]> 2018-10-11 13:14:44 UTC https://padlet.com/jocelyn_shih/22m2br9dkd1r/wish/291701029 When did apes stop turning into humans? - Jermaine https://padlet.com/jocelyn_shih/22m2br9dkd1r/wish/291701754 Technically, apes did not stop turning into humans. This is simply because we are the  evolved version of a common ancestor. ]]> 2018-10-11 13:15:48 UTC https://padlet.com/jocelyn_shih/22m2br9dkd1r/wish/291701754 Are giraffes still developing longer necks than the length they already have? https://padlet.com/jocelyn_shih/22m2br9dkd1r/wish/291701837 Within every generation the neck of the giraffe grew every so slightly longer than the original parents, which took millions of years for the neck to evolve to the way it is now. Therefore the neck of giraffes are still slightly growing through time as evolution is a never ending process of change.

Humans are “modern species” that have transcended into different paths from primates. 
Through this, apes have developed a genetic mutation separate from human DNA. A mutation that does not lead apes to having human qualities.
 Dear Science states, “First of all, the creatures we call apes are our cousins, not our ancestors. Which would make it very hard for them to evolve into something like us.” 
In significance to this:  We did not come from these hairy mammals. We are however, closely related to them. 

WHAT MAKES APES AND HUMANS SIMILAR?
Apes and Humans develop similarities such as the ability to revolutionize tools in terms of survival. Communication plays a vital role too in terms of hunting, travel and protection from possible predatory threats.

When spices reproduce and it exceeds environmental resources, this starts to allow species to slowly mature till the next generations reproduce. More species are being born than they can live. Thus, this can lead to species with genetic disadvantages to die before reaching reproductive maturity. Overpopulated species with genetic advantages can live long enough to reach reproductive maturity, passing on genetic hereditary traits to the next generations.
Advantages also leads to the formation of new species such as adaptations in the climate, the food supply, same spices competition, niche competition, other species competition, effective reproducing, quickly maturing, as well as inherited genetic strength of passing beneficial adaptations leading the species to blossom. 
Similarly, geological changes can pressure populations, resulting in a natural selection of genetic and species variation. For example, volcanic eruptions can force species to make different adaptations to their environment, leave their environment, or become extinct.

When was the first blue eye encounter? https://padlet.com/jocelyn_shih/22m2br9dkd1r/wish/308114481 New research shows that blues eyed people are all believed to have a single, common ancestor.It is believed that originally we all had brown eyes,  A team at the University Copenhagen have tracked down a genetic mutation which took place 6-10,000 years ago and is the cause of all blue eyed alive humans.
