How long would it take for birds to develop live birth like mammals and certain reptiles and fish do?

Generally, smaller mammals live short lives and larger mammals live longer lives. Bats are an exception to this pattern, they are relatively small mammals that can live for one or more decades in natural conditions, considerably longer than natural lifespans of significantly larger mammals. Mammalian lifespans range from one year or less to 70 ... Mammals (from Latin mamma, 'breast') are a group of vertebrate animals constituting the class Mammalia (/ m ə ˈ m eɪ l i ə /), and characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones.These characteristics distinguish them from reptiles and birds, from ... Glyphosate treatment in clear cuts caused dramatic decreases in the populations of birds that lived there (MacKinnon et al., 1993) Effects of some organochlorines (OCs) on fish-eating water birds and marine mammals have been documented in North America and Europe (Barron et al., 1995; Cooke, 1979; Kubiak et al., 1989). Despite the continuing ... Do not store food, garbage or other recyclables in areas accessible to bears. Do not feed birds or other wildlife where bears are active. Feed outdoor pets a portion size they will completely consume during each meal and securely store pet foods. Keep grills and smokers clean and stored in a secure area when not in use. A clever carnivore, the crocodile has many adaptations that have equipped it to last on Earth for 55 million years, including a valve that allows the reptile to open its jaws underwater—the better to eat prey with. And yes, the crocodile is different from the alligator—gators have wider snout, and live in freshwater environments, while crocs have U-shaped snouts and live in saltwater. Tiger sharks mate via internal fertilization and give live birth to as many as 80 or more small young. Though they give live birth, tiger sharks do not connect to their young through a placenta, like in most mammals. Instead, embryos develop inside individual eggs until they hatch. Only then does the mother give birth to live juveniles. Monotremes like the duck-billed platypus and echindnas are a whole category of egg-laying mammals that are the only mammals which do NOT give birth to live young. Instead, animals like the platypus and echindnas actually lay eggs. The Three Different Types of Mammal Births Monotremes Vampire bats glide stealthily through the night air as they search for food. Like the legendary monster that they’re named after, these small mammals drink the blood of other animals for survival. They feed on cows, pigs, horses, and birds. Found in Mexico and Central and South America, vampire bats even occasionally bite humans for blood. The evolution of mammals has passed through many stages since the first appearance of their synapsid ancestors in the Pennsylvanian sub-period of the late Carboniferous period. By the mid-Triassic, there were many synapsid species that looked like mammals.The lineage leading to today's mammals split up in the Jurassic; synapsids from this period include Dryolestes, more closely related to ...

2021.11.27 07:54 Poltargot91 Do you use at least one power when fighting Elite Bloonarius/Lych solo?

I want to see how many of us use powers or not vs Elite Bosses. Nothing personal, I'm just curious. I used supply drops and one insta for the first 2-3 weeks, then used just 1 suppy drop, then stopped using them thanks to game knowledge.
What about you, are you (still) using powers or you're smart enough to not need to use them?

Hi, I want to buy Earfun Air Pro 2 and it has auto ear detection function where it can pause the sound when we take off the buds. So my question is, does it will disconnect when I take off either buds while on PC (Windows 10) ? I want to use it for gaming on PC.

2021.11.27 07:54 wardersotiatryr2ld the Sovryn Era : The best of Defi

As we move closer to the end of the year the market seems to go back and forth with dips and pumps here and there, though we seem to be in the bullish season, BITCOIN has really been going a little bit up and down; the dips amidst this bullrun is entirely an opportunity to join the train.
A particular project I am focusing on is SOVRYN it has really achieved a lot in the space recently. On the platform, the distribution of earned fees in Bitcoin has been set automatically for all SOV stakes and also the team introduced a pre-sale for its Bitcoin based stablecoin called MYNT. The pre-sale gathered up to $8.5m+ with over 370k+ SOV deposited in exchange for MYNT.
There is also a subprotocol which offers 0% interest fee cost while borrowing SOV on the Platform, without mincing words this would be a very interesting feature where one can borrow to purchase any other asset at no interest cost with the only condition attached it is using a BTC backed stablecoin called ZERO.
Now the ever ready Sovryn team is also still pushing the adoption by partnering with local banks in El-salvadore and banking the unbanked by bridging DeFi and tradfi. Hopefully these activities cause a bullish move and we have SOV up and running again, for now I just DCA.

2021.11.27 07:54 Acceptable-Study3040 Looking for a nice resort/hotel in Georgia to take a study vacation in

Hi all. I'm a medical student from another country. I'm interested in Georgia and I wanna vacation over there for Christmas, hiking around, exploring the sites and castles, and mostly sit in the place where I will be staying, and study.
Any recommendations? Looking for a really nice place, since I'll stay in it most of the time and study. I would really like a place that has a sauna. Also I'm vegan so if there's a vegan friendly place that would be great.
Also, is the weather too cold to go outside ? I'm hoping it's a warm country even in the winter, but I don't really know.
