Evolution of Mammal Traits

Sometimes I'm fascinated at how mammals become mammals. Most mammals are so similar to one another in our number of traits that it amazes me to think that the diversity of mammals today came from a very small number of species in the past. One trait the most people don't even know about is our acute hearing. I imagine most people never think about how we mammals hear differently than other species. We have three bones in our inner ear, two of which are unique to us. (Most animals use parts of their jaw bones to hear.) Another unique adaption is the fact that we feed our young with milk from the mother. This is such as complex function, I can imagine why some people find it easier to accept we are just "made" this way. However, there is evidence that shows the path of evolution, and it isn't in the form of fossils.

The platypus is likely the most primitive mammal alive today. It lays eggs. It does feed it's young with a milk-like secretion, but not with nipples. Instead, it has a hairy patch its underside. The secretions not only serve to feed their young, but apparently, it also adds an additional layer of protection to the egg shell before the hatchlings emerge.

Then, the path to marsupials is given to us in the form of the second most primitive mammal, the echidna. This is a group of a few species that also lay eggs. However, when it lays its eggs, it places them into a pouch. This likely represents a primitive marsupial, before egg laying was replaced by embryo birth.

Marsupials in turn do have one advantage to placental mammals (that's us). There are less complications from having to protect the embryo from the mothers immune system since the young leave the womb at such an early stage.

Of course, the advantage of having a placenta during pregnancy has its own advantages, which can be seen by the fact that placental mammals are now the dominate form of mammals.

Even given our high level of development, one can see that mammals have not dominated the Earth for very long. For example, there are far fewer varieties of mammals than reptiles. Given the advancements of mammals, it will be interesting to see what future classes of species evolve on our world.

I've been reviewing items online almost as long as I've been on the internet. I've started leaving reviews of restaurants in Silicon Valley now. Check them out here:

Currently, I have reviews for Straits, Pizza Antica and Thea. So far, my reviews are centered around Santana Row, but it will expand.

Home schooling does not mean Parent schooling

In recent news here in California, there is a case in the courts now that is reinforcing California state law which basically says "persons between the ages of six and eighteen" are to be in "public full-time day school," or a "private full-time day school" or "instructed by a tutor who holds a valid state teaching credential for the grade being taught". This has been state law for a very very long time. Yet now, we have scofflaws that claim they have a right to teach their own children whatever they want. Homeschooling is legal in California, as long as it is conducted per state mandated curriculum and by a licensed instructor. The excuse used by the scofflaws? "Parents should not have to attend a four-year college education program just to teach their own children." It's the old argument, "Oh my god, this is too hard to do right, so I'm just going to do it wrong and be happy!" Lazy, lazy, lazy. Oh and cheap too! You don't care enough about your child's education to pay for it yourself (since you don't want the state to do it)! Mr and Mrs Long, in my opinion, you are lazy, selfish, and cheap jerks who obviously don't do enough reading into anything to know what is the truth. You have no business trying to pass on your ignorance to anyone's children! That said, it is important for parents to teach their children about their own experiences, beliefs, hertitage, etc. Parental schooling does not mean home schooling. It is not a replacement for a formal education. It is something that should be done in conjuction with a formal education. Home schooling is just a place to do it if the law is followed. Parental schooling is not the same thing. If you don't agree with something taught in the classroom, then discuss it with your children. It is as simple as that.

Weeklong birthday

This has been a weeklong birthday of sorts. Monday, Allie took me out to Red Lobster. I had something with two lobster tales. It was fairly good, but at it made me miss Legal Seafood in New England. Yesterday, Ronie and Fern had a small a BBQ for me at their place. They got a super rich chocolate cake. We took home the remainder of the cake, but I'm not sure how I'm going to eat it all. Tonight, Allie and I invited her parents to join us for dinner at Cascal in downtown Mountain View. They ended up paying for it it with the excuse that it was still my birthday.

First time in awhile

For the first time in awhile, I went out. I met up with Miriam and some of her friends a Old Pro in downtown Palo Alto. The evening wasn't too crazy. There was some new randoms from her work place. I had trouble making it there though because I wasn't able to leave work until like 7pm. It was fun getting out for the evening. Allie, oddly enough, had separate plans for her friends, also in downtown Palo Alto on the same evening, but those fell through and then she got sick. Otherwise, she would've come too.
