Perissodactyla by Samuel Gulen https://padlet.com/sg2021/uf93bqmnjlkx Made with a lightning strike of genius By: Sam Gulen en-us 2017-05-24 13:22:32 UTC 2025-11-03 01:44:21 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Bigthunderstorm.png Major characteristics sg2021 https://padlet.com/sg2021/uf93bqmnjlkx/wish/173620843 All perissodactyla are hoofed and have at least 3 toes.This is a major structural characteristic of the perissodactyla. They all share similar behavior. This could be another characteristic such as they are all herbivores. Most animals in this category eat plants or graze grass. They also reproduce sexually rather then asexual reproduction. Some Perissodactyla like rhinos are larger and the gestation period for a fetus is longer and can range from 11-16 months. This is because they are larger animals. Most perissodactyla are very shy and prefer to be alone. When in the wild they are very territorial like a rhino. Domestic perissodactyla like horses can be very social creatures though training.]]> 2017-05-24 13:27:47 UTC https://padlet.com/sg2021/uf93bqmnjlkx/wish/173620843 Horses sg2021 https://padlet.com/sg2021/uf93bqmnjlkx/wish/173819936 Horses are herbivores and tend to live in herds. The horse is a perissodactyla because of the three toes. Horses tend to be social animals but when together are very territorial. Horses come form the claddogenesis witch is an old dog like creature that lived around 55 million years ago. The little horse or the hypothermia is one of the oldest evidences for horses. This shows that horses are adapting to the environment today. There are also many different species of horses.]]> 2017-05-25 13:38:02 UTC https://padlet.com/sg2021/uf93bqmnjlkx/wish/173819936 Rhino sg2021 https://padlet.com/sg2021/uf93bqmnjlkx/wish/173819962 Rhinos are very territorial animals like the rest of the perissodactyla. Rhinos come from the  Hyrachyus eximus that come from north america. This i a creature that also lived back around 55 million years ago. The coelodonta antiquiatis  is one of the oldest fossils supporting evidence for evolution. This creature is one of the first in the rhinoceros family. This supports evolution and that there are many different kinds of rhinos today. This also shows that rhinos are adapting to the environment today.]]> 2017-05-25 13:38:08 UTC https://padlet.com/sg2021/uf93bqmnjlkx/wish/173819962 Classification sg2021 https://padlet.com/sg2021/uf93bqmnjlkx/wish/173980209 Common Name- Horse

Tapirs are social but territorial like other perissodactyla animals. The tapir comes from the Heptodon witch was found in north america and some tropical parts of the world. Today there are many different kinds of tapirs that live all over the world. This fossil supports evolution and that these animals are still adapting to the environment around them today. ]]> 2017-05-26 13:29:31 UTC https://padlet.com/sg2021/uf93bqmnjlkx/wish/173985222 Chromosome comparison sg2021 https://padlet.com/sg2021/uf93bqmnjlkx/wish/174408160
Horses have 62 chromosomes.
Rhino 84 chromosomes and
Tapir have around 80 chromosomes .This is a karyotype of a male horse. If you compare this to a male human you can see that there are more pairs of chromosomes. Looking more in depth certain chromosomes alleles line up differently than a human. Looking at some of the other alleles they line up almost exactly similar. This is because this is what makes certain proteins that are similar in all animals and humans. This protein SBK2 and it builds tissue in the heart The Evolutionary relationships. A researcher at MIT found that horses suffer from some of the same behaviors and diseases of humans. Through DNA sequencing of horses we now know that they went through a similar process of evolution. Protein analysis of a horse shows that they make protein very similar to humans using protein synthesis. This process that they evolved in a similar process by going from a simple organism to more and more complex over time.

This can be seen in all three of the animals shown. Horses, Rhinos and tapirs show some form of natural selection. They also come from a diverse group of other related animals. ]]> 2017-05-30 15:12:08 UTC https://padlet.com/sg2021/uf93bqmnjlkx/wish/174434491 evolution sg2021 https://padlet.com/sg2021/uf93bqmnjlkx/wish/174611051 Geographic isolation occurs in tapirs. Tapirs are found in many different parts of the world like central America and southeast Asia. This means they are separated from mating from each other so specific types of tapirs occur. Both rhinos and horses participate in random mating. This is when a partner is chosen is not influenced by phenotype. This is why there is a less variation in there species then horses. ]]> 2017-05-31 13:01:30 UTC https://padlet.com/sg2021/uf93bqmnjlkx/wish/174611051 Evidence sg2021 https://padlet.com/sg2021/uf93bqmnjlkx/wish/174614360 looking back at the fossils shown we know that perissodactyla evolved from a common ancestor. These common ancestors are shown in a phylogenetic tree. With the help of mechanisms this can be used as evidence for evolution. Such as a horse adapting to the environment around them. Horses and tapirs have gone through geographic isolation in some form having species in different parts of the world.]]> 2017-05-31 13:18:03 UTC https://padlet.com/sg2021/uf93bqmnjlkx/wish/174614360
