Latest Challenges to the Teaching of Evolution

Evolutionary Tree Information:

Fossils and DNA confirm humans are one of more than 200 species belonging to primates. Within that larger group, humans are nested within the great ape family. Although we did not evolve from any of the apes living today, we share characteristics with chimpanzees, gorillas, and orangutans (the great apes), as well as other apes. We most likely evolved from Homo heidelbergensis, the common ancestor we share with Neanderthals, who are our closest extinct relatives.

Human evolution
From Wikipedia, the free encyclopedia

This article is about the general evolution of humans. For a timeline see Timeline of human evolution.

Human evolution, or anthropogenesis, is the origin and evolution of Homo sapiens as a distinct species from other hominids, great apes and placental mammals. The study of human evolution encompasses many scientific disciplines, including physical anthropology, primatology, archaeology, linguistics and genetics.[1]

The term "human" in the context of human evolution refers to the genus Homo, but studies of human evolution usually include other hominids, such as the Australopithecines, from which the genus Homo had diverged by about 2.3 to 2.4 million years ago in Africa.[2][3] Scientists have estimated that humans branched off from their common ancestor with chimpanzees about 5–7 million years ago. Several species and subspecies of Homo evolved and are now extinct. These include Homo erectus, which inhabited Asia, and Homo sapiens neanderthalensis, which inhabited Europe. Archaic Homo sapiens evolved between 400,000 and 250,000 years ago.

Most in the animal kingdom practice homosexuality. That tells me, it's normal animal behavior.

But, actually, some same-sex birds do do it. So do beetles, sheep, fruit bats, dolphins, and orangutans. Zoologists are discovering that homosexual and bisexual activity is not unknown within the animal kingdom.

spendi, I posted this earlier, but I'll post it again from the National Geographic:

Try to refute that statement if you can.

I don't need to refute it. My eyes tell me its bullshit. I grew up on farms. Evolution theory says its bullshit. And the usage "not unknown" is an admission of bullshit. As is the usage " are discovering".

I am talking about orgasm. The NG has to keep in with its left wing followers. It's pop science run as a business. It doesn't want to alienate any readers.

Which same-sex birds? Which sheep.

Anyway, lets see what your pals have to say.

The reason Bonobos are perceived to be a matriarchal species is that females tend to collectively dominate males and commonly engages in casual sexual activity, as well as significant homosexual contact.[10][11]

I've obviously got you rattled Cyclo. You're showing signs of "resistance" if you know what that is. Which I doubt.

Resistance analysis is a standard procedure in psychiatry, psychology and bar conversations.

I have read on homosexual acts of animals as far back as the 1950s. Some animals also attempt cross species sex.

Some animals also attempt cross species sex.

Homosexual behavior is defined as genital contact, genital manipulation or both between same-sex individuals. Available data indicate that this behavior is phylogenetically widespread among the anthropoid primates, but totally absent among prosimians. The majority of the 33 species that demonstrate homosexual behavior do so rarefy, but for a substantial number (N =12) it appears to be a more common pattern under free-ranging conditions. I summarize data on homosexual behavior as it relates to form, living condition, age, sex, social organization, and ecological context, and discuss hormonal, demographic, and sociosexual theories for primate homosexual behavior. Among adult primates, the behavior is not the product of abnormal excesses or deficiencies in androgens. Prenatal excesses of androgens may have some effect on the expression of female homosexual behavior, but these effects might vary over the life span, and data are equivocal at present. Demographic processes that result in skewed sex ratios can favor the expression of homosexual behavior in a population, which causes intraspecific variation. I examine several sociosexual explanations, including (a) proceptivity enhancement, (b) receptivity reduction, (c) dominance assertion, (d) practice for heterosexual copulation, (e) tension regulation, (f) reconciliation, and (g) alliance formation. An evolutionary scenario highlights the transformations this behavior underwent during the evolution of the anthropoid primates. I suggest exaptation as a theoretical framework for interpreting homosexual behavior and conclude that future consideration of sexual selection among primates should address homosexual components of this process.

Ah, the 'I've never seen it' theory of science.

Sure--what else is there. I've never seen aliens or flying saucers. I've never seen action at a distance. Your baby argument could be used to defend both of those. And underground cities on Uranus.

I've seen thousands of animals, maybe hundreds of thousands, in the wild and domesticated. I gave two other reasons as well.
