Falling in love can make you feel all sorts of crazy and wonderful So here are some signs that you and your partner are chemically bonded together, according to science. If you haven't been much of a post-sex cuddler, but you're new There's a lot of empathy in relationships where couples are deeply. However, scientists also use the term “fact” to refer to a scientific don't understand evolution still use the notion of the missing link to mean “one great we haven't discovered a single fossil indicating that evolution is wrong. One reason is that many studies of romantic relationships are carried out not are certainly capable of close relationships, many of them haven't matured journal Social Psychological and Personality Science, showed not only that . This doesn't mean a full-out sexual encounter has to follow from that touch on the cheek.

By no means are the following the only important aspects of a relationship: But other qualities definitely matter, too. And those qualities are definite signs you are with the right person, because the right person supports and helps you personally, professionally Since I'm a heterosexual male I wrote this from my perspective; the following is neither gender nor sexual orientation specific. You only have to think about what you want to say, not how you need to say it.

We all manage up, or sideways, or down, choosing our words carefully in order to frame an idea, or a suggestion, or feedback, or constructive criticism Oftentimes, in professional or personal settings, we feel we need to think more about how we want to say something than the essence of what we need to say. When you're with the right person, you don't think about how you want to say something.

You just say it, partly because you know they will understand When you have bad news, your spouse is the first person you want to tell -- not the person you most dread telling.

When good things happen, plenty of people can't wait to tell their partner. But what about when something bad happens--and especially if that "something bad" is in some way your fault?

That's a much harder conversation to have. You know she'll listen, commiserate, empathize Your partner understands the relationship between money and time together. According to at least one study, if one spouse commutes longer than 45 minutes, a couple is 40 percent more likely to get divorced.

So say you or your significant other is offered a new job with a 20 percent bump in salary According to another study, economists determined that a 40 percent increase in pay is necessary to make an additional hour of commuting time worthwhile in terms of personal satisfaction and fulfillment. In simple terms, a couple of dollars an hour more in pay won't make you happy if you have to drive an extra hour every day to earn it.

And it definitely won't help your relationship. Your partner doesn't expect you to change overnight. I have a really bad habit I'm trying to overcome.

Actually I have plenty of bad habits; this is just one. I often agree to do something way off in the future A therapist could probably have a field day figuring out why I do that.

So invariably I'll say something like, "You know, I don't think I want to go [somewhere] after all Just suck it up and go," or, "People are going to be disappointed if you don't go," my wife smiles and says, "I really hope you go. You always learn things and meet cool people. And later, you're always glad when you do [that]. What can I do to help you get ready? She knows that's how I am, and instead of criticizing me, she's supportive and helps me work through it.

The right person knows there are things about you that you want to change, but they don't expect them to change overnight. They're willing, for as long as it takes, to help you work through your quirks. Your partner never lets you give up on yourself. Showing patience is an under-appreciated way to show genuine confidence in your partner -- because it shows that, no matter the current struggles or issues, you truly believe in him.

When I first changed careers, I really struggled. I worked impossible hours just to scratch out a semblance of the income I once generated. But every time I talked about giving up, my wife kept me centered by gently reminding me that all the work I was doing would pay off if I stayed the course.

No success is overnight. And speaking of success Your significant other helps you be more successful. Researchers at Washington University in St.

We have still not found the missing link between us and apes

Louis found that people with relatively prudent and reliable partners tend to perform better at workearning more promotions, making more money, and feeling more satisfied with their jobs. That's true for men and women: Check this out for more on how a good partner sets a good example and makes it possible for you to become a better you. Your partner doesn't talk about you; they talk about the cool things you do.

We all know people who openly badmouth their significant others: When you love -- and respect -- the person you're with, you don't gossip about their personal failings. You talk about their great qualities because you're happy for them Or, more likely, you don't say anything at all, unless asked, because quiet pride is the best pride of all.

Your partner knows you well enough to have the ideas you should have had.

BBC - Earth - We have still not found the missing link between us and apes

The day Mark Cuban appeared, one young man spent the entire day manning the green room door. I started to feel sorry for him; here he was at this cool conference and yet he was stuck in a chair guarding a door in a lonely hallway. So I stopped to talk. He was surprisingly happy about doing that job but mentioned that he would love to meet Mark Cuban. I didn't say so, but I knew that would never happen: Cuban's time was tightly scheduled, plus local and national media were angling for time.

The constant crowd of people wanting something from him would make that impossible. A little later I called my wife and mentioned that the volunteer hoped to meet Mark. She said, "You can make that happen. Why don't you try?

They even have a reasonable idea of what it looked like and how it behaved. Even before Darwin formalised the idea of evolution through natural selection, it was clear that humans were primates — although earlier scientists did not think this categorisation had any evolutionary implications. Apes in general represented evolutionary staging posts on the road to humanity Darwin himself was initially reluctant to directly address human evolution.

He barely mentioned the subject in his famous book On the Origin of Species. Darwin's colleague, Thomas Henry Huxley, was perhaps the first to try to identify humanity's roots using well-reasoned evolutionary thinking.

In his book Evidence as to Man's Place in NatureHuxley said it was " quite certain ", anatomically speaking, that humans are most similar to gorillas and chimpanzees.

One of these two must be humanity's sister species, although Huxley was not sure which. Huxley's ideas had a significant impact on 19th and early 20th Century evolutionary biologists.

Many enthusiastically embraced the idea that chimps or gorillas — or even both — were our sister species. But they went further. To these biologists, it seemed that apes in general represented evolutionary staging posts on the road to humanity. View image of Gibbons are more distantly related to us Credit: Meanwhile the "great" apes — gorillas, chimpanzees and orangutans — showed the anatomical features our ancestors possessed at the moment they split away from the other apes and began to develop a uniquely human appearance.

Gorillas and chimps were not simply our sister species: This led to some very particular ideas about how the LCA looked and behaved. Primates in general particularly monkeys are often relatively small-bodied, and they scamper around in forest canopies by running along branches.

The Real Science of Forensics

But apes are unusual primates. Most have big bodies with extraordinarily long arms. They often get around by swinging below branches rather than running along the top of them — a form of locomotion called "brachiation". According to many of these early researchers, the LCA was a large-bodied, long-armed, brachiating ape. By the late s, researchers were fleshing out the LCA even further. An anthropologist called Sherwood Washburn pointed out that chimpanzees, and particularly gorillas, actually spend significant amounts of time moving around on all fours on the forest floor.

Humans just are not particularly "evolved" Both apes use their arms in an idiosyncratic way when they walk: To Washburn it made sense that the LCA "knuckle-walked" too. The behaviour could even be seen as a stepping-stone on the way to walking upright on two legs, he wrote. But it would be wrong to think that everyone was on board with these ideas of a brachiating, knuckle-walking, chimp-like LCA. In fact, almost from the moment that Huxley first put pen to paper, a minority of scientists were arguing that the earliest human ancestors — and the LCA — was decidedly not chimp-like.

For instance, just a decade after Huxley's book, biologist St George Mivart argued that humans shared many features in common with monkeys or even lemurs. Meanwhile, from onwards an anatomist called Frederic Wood Jones argued that humans had a lot more in common with tarsiers than with chimpanzees or gorillas.

Lemurs, tarsiers and monkeys are primates, but they have been evolving independently of the apes for tens of millions of years. How could anyone argue that humans are closely related to these groups? There is a simple and astonishing explanation, wrote anatomist William Straus in the s.

Humans just are not particularly "evolved". View image of A mountain gorilla Gorilla beringei beringei Credit: But human arms, hands, legs and feet are not as highly specialised as we might assume. The more ancient the divergence between species, the more time those species have had to accumulate their own molecular differences What Straus and a few others were really getting at is that humans show none of the specialised features that allow other apes to swing through the trees.

It made sense to at least consider the possibility that humans split apart from other primates before the apes evolved brachiation, or knuckle-walking for that matter.

Straus could not say exactly which species should be recognised as our sister. But the LCA could well have been a relatively small-bodied primate that ran along branches rather than swinging beneath them. This disagreement continued for several more decades, says Nathan Young at the University of California in San Francisco. In fact, even into the s it was not clear from anatomical features alone exactly where humans slotted into the primate evolutionary tree. Then, just a decade later, this uncertainty vanished.

By the late s, almost all evolutionary biologists were willing to accept that chimpanzees, and their close relatives the bonobos, together form humanity's sister species. To understand this turning point in the story, we have to skip back a few decades and look at what was going on in a completely different branch of science.

View image of Australopithecus afarensis lived around 3 million years ago Credit: Working with his colleague, Emile Zuckerkandl, Pauling developed a truly revolutionary idea: Ramapithecus was discovered in Pakistan and dated to about million years old "It was a revival of an idea proposed by bacteriologist George Nuttall inthat if you compared blood serum you could get a sense for the evolutionary closeness of species," says Jeffrey Schwartza physical anthropologist at the University of Pittsburgh in Pennsylvania, US.

From the number of differences between the two sets of molecules, and an estimate of the rate that those differences accumulate, the researchers calculated that humans and gorillas had last shared a common ancestor roughly 11 million years ago. Only fossils could tell us when common ancestors lived, they argued.

Many reportedly described Pauling and Zuckerkandl's concept as crazy. But the molecular scientists stuck at their work and, a few decades later, they won over the sceptics — due in no small part to new fossil finds.

All manner of fossil primates, including apes, had come to light by the s. One of them, an ape called Ramapithecus or sometimes Sivapithecus, had begun to look a lot like a direct human ancestor.

View image of A jawbone of Ramapithecus Credit: The molecular people said 'See? We were right all along! And if the million-year-old Ramapithecus really was a human ancestor, gorillas and humans cannot possibly have shared a common ancestor just 11 million years ago, as Pauling and Zuckerkandl were suggesting.

But these conclusions about Ramapithecus came almost exclusively from a study of the ape's teeth, which were more or less the only parts of the ancient ape that had been unearthed by the s. In the early s, more Ramapithecus fossils were unearthed, including fragments of the face. They showed that the ape looked like an orangutan, not a human. Palaeontologists were astonished, but molecular scientists were not. By now they had established that humans, chimps and gorillas were all closely related and shared a common ancestor within the last 11 million years or so, and that orangutans were slightly more distant relatives with a deeper prehistory.

According to their thinking, a million-year-old ape would be unlikely to look distinctly human, because it predated the appearance of the human lineage. But it might well look orangutan-like. In the s and 90s, the molecular community built on such successes.

View image of A western lowland gorilla Gorilla gorilla gorilla Credit: Huxley's work in the s had encouraged many scientists to see the LCA as chimp-like, and the molecular work of the s and 90s seemed to vindicate the idea. This was not the only conclusion from the molecular work. The DNA studies also put an approximate date on the human-chimpanzee split:
