Summary

In this episode we explore the diversity of the animal kingdom. I first discuss the history of taxonomy and give an overview of some key concepts such as morphological similarity, phylogenetic analysis, systematics, cladistics, binomial classification, and the taxonomic hierarchy. Then follows an explanation of the diversity of and relationships between the major animal phyla, including arthropods, echinoderms, molluscs, and many others, with special emphasis is given to the classes and orders in the phylum of chordata (vertebrates).

And so, you're listening to the Science of Everything podcast episode 69, animal diversity, and I'm your host, James Fodor.

0:40.3

In this episode, I'm going to discuss the diversity and biological tax are found in the kingdom of

0:47.1

animalia or animals. The goal here is to give a sense of the diversity of the animal kingdom and the

0:53.4

relationships between different

0:54.4

types of animals. Obviously, I'm not expecting people to remember even a small fraction of

1:00.3

all of the different... Obviously, I'm not expecting people to remember even a small fraction

1:07.7

of all the different types of animals that I'm going to specify, but I'm just hoping that in this episode you'll get a sense of the rich diversity of the animal kingdom.

1:15.2

And broadly speaking, you'll pick up some ideas of what different types of animals there are

1:20.0

and how they relate to each other, which is often something that many people, myself included,

1:24.8

don't necessarily know very much about.

1:26.8

So in this episode, I'm going to talk about basically all of the types of animals that are not

mammals.

1:33.5

So this includes all of the various phyla outside of chordates, arthropods, mollus, echinodems, etc.

1:40.7

And also most of the different classes within the chordate order,

1:45.7

including the bony fish and jawless fish and birds and reptiles and amphibians and so on.

1:52.0

And for the next episode, I'll save talking about the mammalian class, which obviously is

1:58.5

where humans and most of the animals that we sort of are familiar with, fit in.

2:02.4

So I'll leave them to their own episode.

2:06.2

Also, I must apologize if you hear additional extraneous background noise in this episode,

2:13.0

because I'm actually recording this and these two episodes outside.
