The teeth of the steropodon was similar to later platypuses discovered.

Some of these mutations include egg laying, which is not common in mammals at all. It is likely that the platypus inherited this from a past ancestor and is one of the few mammals who retained that trait. Another one of these mutations include venomous spurs, male platypuses have venomous spurs on their rear limbs, this was caused by a mutation in their toxin-producing genes. ]]> 2023-05-21 23:36:53 UTC https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599107826 lukaslobdell https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599111181 2023-05-21 23:42:06 UTC https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599111181 lukaslobdell https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599113370 2023-05-21 23:45:08 UTC https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599113370 lukaslobdell https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599113506 There are no other species of platypus.

Platypuses are native to freshwater habitats of Australia. This includes rivers, streams, and lakes. Platypuses are know to colonize near by areas within their ability, this introduces the ability to exchange genetic material. The gene flow of platypuses is very limited as well due to so many isolated populations from human intervention and other factors. They have low chances to exchange their genetic material between populations. ]]> 2023-05-22 00:00:04 UTC https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599123412 lukaslobdell https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599206060 2023-05-22 01:19:15 UTC https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599206060 lukaslobdell https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599219792 The platypus is a great example of divergent evolution. The platypus has inherited traits from many different animal groups. From the mammal group, platypuses nurture their young with milk. While a typical mammal has teats to provide milk, the platypus sweats milk to feed their young. It also inherits traits from reptiles such as having the ability to lay eggs, and having venomous spurs. ]]> 2023-05-22 01:29:07 UTC https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599219792 lukaslobdell https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599226086 In the case of parallel evolution, the platypus has inherited the trait of electroreception which is also inherited from fish and aquatic animals. Even though the platypus is a mammal, the platypus still inherited this trait because the platypus lives a semi-aquatic lifestyle. ]]> 2023-05-22 01:33:59 UTC https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599226086 lukaslobdell https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599230948 An example of convergent evolution for the platypus would be the fact that the platypus has venomous spurs. The platypus has almost no relation to animals with venomous abilities, the platypuses environment just required that the platypus inherits that trait. ]]> 2023-05-22 01:37:55 UTC https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599230948 lukaslobdell https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599237157 2023-05-22 01:42:58 UTC https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599237157 lukaslobdell https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599240204 Females choosing a mate is not usually a hard decision for them and are not particularly picky. They will usually go for the most dominant male in their area. However males usually engage in some sort of competition to choose a female, this may include establishing territories, and some sort of fighting. The most dominant platypus will usually be the one to mate and pass on their traits. ]]> 2023-05-22 01:45:38 UTC https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599240204 lukaslobdell https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599243677 2023-05-22 01:48:38 UTC https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599243677 lukaslobdell https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599248203 Reducing the effects of genetic drift for platypuses is essential.

The mammary glands in female platypuses differs from other mammals, but they serve the same function and purpose. ]]> 2023-05-22 01:58:13 UTC https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599255268 lukaslobdell https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599258461 2023-05-22 02:00:05 UTC https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599258461 lukaslobdell https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599265024 There are two main vestigial organs in the platypus. The first one is the eyes, the eyes in the platypus have becomes virtually useless over the course of its evolution. The platypus relies on its other senses mainly including electroreception. The other vestigial organ or structure would be the claws located on their webbed feet, these may have been used for a different purpose from their ancestors. They are now a lot smaller and don't really serve a purpose since the webbed feet are used for swimming and diving. ]]> 2023-05-22 02:04:43 UTC https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599265024 lukaslobdell https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599269298 2023-05-22 02:07:41 UTC https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599269298 lukaslobdell https://padlet.com/lukaslobdell/nhuwy0tctdm41gq4/wish/2599283848 Through genome sequencing for the platypus, the relationships between other species and platypuses has been discovered.

The platypus is one of only two species of mammals to be able to lay eggs. Also the platypus has venomous spurs that are not very common in mammals. The platypus lives a semi-aquatic lifestyle. The evolution of the platypus is very unique as well because the platypus is the only species of its kind. The group of platypuses is called the monotremes, of which only five species are in that group today.
