"Conflicted Relationship" Between Whales and Humans, ACS | Marine Science Today
The evolutionary origins, ecology and diversity of cetaceans (whales, years, the phylogenetic relationships among the Mysticeti still remain uncertain. Morphological and molecular approaches have often generated conflicting arrangements. .. making breathing very efficient (for example humans exchange slightly more. Check out some highlights from the American Cetacean Society conference , "Whales and Humans: A Conflicted Relationship" that came. Whales and Humans: A Conflicted Relationship We also held our traditional pre-conference all-day whale watching trip on Friday November 9th, venturing out.
Within other groups e. An individual's prior attitude towards, and values of, wildlife and nature e. An individual's previous experience and knowledge of a species or group. The relationship between species and humans, for example cultural significance, utility value or conservation status. Human perceptions of individual species in terms of aesthetic value, assumed intelligence, threat, etc. Other influential factors may be cultural significance and perceived sentience.
Kellert 167 repeatedly notes the significance of this factor, yet does not discuss it in detail. Only one study to date has considered this factor in any depth.
However, these studies were on a small scale using a limited number of species. It is generally presumed and supported by Plous' 8 study that humans will prefer species' that are perceived to be similar to their own.
However, Beatson and Halloran 9 found a converse effect, in that after subjects watched a video of bonobos mating their subjects experienced negative feelings towards this species. It is suggested that recognition of similarities between humans and animals may make humans uncomfortable and consequently less disposed to positive feelings towards them. A major issue with studies such as that by Plous 8 is that they have used human perception of species similarity to themselves as a measure.
In terms of a species position in society, this may well be the most valuable gauge of similarity as it is this same human perception that will determine overall attitudes.
However, human perception is subjective and so if participants perceived a species to be similar to humans then it would be recorded as similar, independently of any objective measure. Thus, if subjects were to perceive a dog to be more similar to humans than is a monkey, this would be held to be true, irrespective of the cladistical evidence. Secondly, human perception is affected by contextual cues, and may change over time.
For instance, as an individual's knowledge and understanding of a species changes, then that species may appear to be more or less similar to humans. By way of contrast, any correlation between an objectively defined measure of species similarity and our preferences may imply that an adaptive function exists for such biases. Moreover, an objective study would be more widely applicable because it would be less dependent on the individual's knowledge or upon cultural variation.

Despite being a complex and intriguing area of research, particularly with regard to human decisions concerning species protection and conservation, our knowledge and understanding of factors affecting human preferences for different species has barely increased since Kellert's original work was published. Although the potential influence of similarity as a factor has been acknowledged, the biological bases of species' similarity to humans have rarely been adequately defined.
This is despite the fact that socio-psychological research on human—human similarities e. This study takes a multivariate approach with the aim of providing an objective measure of species' biobehavioural similarity, and to test whether this measure of human—animal similarity influences our preferences for other species. Thus, the study questions if a species' biobehavioural similarity to humans affects human attitudes towards it.

The term biobehavioural is used here to reflect that a wide range of biological, behavioural and social factors are involved in a multidimensional definition of similarity. Therefore, it does not relate simply to superficial appearance criteria such as body size or coloration, and unless otherwise stated, similarity will be used only with this strict multifactorial meaning for the remainder of this paper.
They come in a variety of sizes and have different behaviors. They also create different behaviors and languages within their own cultures as humans do. Whales are other mammals that feed their young milk too, although it takes plenty more to feed them than human babies! If you observe the behaviors of whales, you will find that they are quite social in nature.

They make clicks and other sounds with their mouths that are used to share information with others in their group. Humans use different types of communication but for the same purpose. Both are quite affectionate in many ways too.
Whales have been seen rubbing and caressing each other as a human couple would. In spite of all their similarities though, humans and whales do have some differences that create quite a few issues for them. First, humans are the only natural enemies that whales have.
Whales and Humans - Whale Facts and Information
Throw in the fact that killing whales for meat, for profit, and for sport has reduced the numbers and you have a huge threat that they are up against. Many whales are destroyed in the water due to the existence of huge ships humans operate. They no longer have the freedom of exploring their waters without human elements that can harm them found everywhere you look. Even fishing ships that have huge nets and mechanisms can injure or kill whales accidentally.
Due to the continued destruction of the environment by humans, whales have had to suffer. Their food source has become very scarce in some areas due to other aquatic life not being able to survive.
